So this is just a guess/theory, but you know how we don't here much about Marceline's mom, right? Perhaps something happened with their relationship. Like it did between Marceline and her dad. This could not be true and it could be proven wrong anytime soon. In the extended preview of “Return to the Nightosphere” I noticed a picture, a family picture. It shows Marceline, her dad, and a women (presumably her mom.) Marceline is much closer to her dad, then her mom. There’s a gap in-between them. To me that’s not a normal family picture. So maybe something happened between them which caused Marceline to resent her mother and grow much closer to her father and that’s why we don’t hear her talk about her mom.Edit

Or I could be wrong and Marceline could just have over all family problems and we just haven’t heard her talk about her mom, Or maybe she’s just a daddy’s girl, or maybe her mom has passed on. Whatever the reason is, I don’t know it. I just wanted to throw that idea out there and see what you guys thought of it.Edit

Now that you've shown me the picture, I seems exactly like something the crew would do to symbolize a fallout! It's kinda a contridiction, though, because Marceline herself said that her mom patched her up when she scraped her knees, meaning she had a relativly close relationship with her, but that was probably memories from before the alleged fallout... which now I realize I just jumped to a huge conclusion from one little picture. A fuzzy one, at best. I'm really bursting my own bubble here, but now that I look at it, it looks more like her older sister, but probably not, I'm terrible at speculation. It would be cool if she had a sister, though, but that would be stupid and make little sense to put a new "foggy area" this late in the series. I myself always thought her mom was just a nice young human who got knocked up before the G.M.W, and died, but this picture proved me wrong, Good Job, it was a perfect argument, with solid evidence... Sorry, I'm playing Ace Attorney.

The more I think about it, the more I want to know the truth. When I think about your "human mother" idea could be right. Marceline is more then 1,000 years old meaning the G.M.W happened close to 1,000 years ago or even more. In the picture the women has skin colored more like Marceline’s Dad, then a normal humans skin color. Here’s a guess maybe her mom was human and she somehow met Marceline’s dad soon before or after the G.M.W. I say that because, remember the episode “Memory of a Memory”, when Finn and Jake ran into young Marceline? There where burning buildings in the background. That could either mean that was the beginning of the chaos of the war or some of the after math of the global event or somewhere in-between the war. (We do not know how long the war went on for.)

Now I would she looks about six in this scene and notice how her hair is? From what I can tell from the family picture she has the same haircut. Though it’s clear that she did not get bit/the bite marks until much older maybe her dad or her mom (or even someone we haven’t seen yet) did it. How her mom could bite her and turn her, you ask? This is going out on a limb but Marceline’s dad is a demon and he could have turned her mom into a vampire after giving birth to Marceline. Maybe to help her survive the war, he could have powers we haven’t seen? Some reason why maybe one of her parents did it to her too?

Though I’m going on here, I hope you don’t mind. We don’t see either parent in that part of “memory of a memory”, but the family picture looks like it was taken around the same time, because of Marceline’s appearance. I’m guessing Marceline can be outside back then either because there is no radiation, or the sunlight blocking the fallout, or maybe because she inherited of her some or dad’s powers. I’ll just say your idea could be right, and this is why I think it could be. Safe to say we won’t know for a while, or maybe not for ever.

No, don't worry! I have a feeling that we're gonna learn all about Marceline's mom, really, really soon. You see, I have a theory about the upcoming episode, you know the one, Daddy's Little Monster? Well, her dad and Marceline have already talked through all their feelings, it would be a boring episode if they had nothing to talk about, so either her dad does something horrible... oh wait, yeah, he locks up Finn and Jake in the Nightosphere ... well, then she probably gets really pissed at him for kidnapping her friends, then they start screaming, throw a few things, then Marceline or her dad yells something about her mom, Marceline starts crying (just a little bit, no waterworks), then, they talk all bout her mom, the end. Now, If that doesn't really happen, it would make an epic fanfiction :P 67.142.178.21 21:56, April 25, 2012 (UTC)

Whatever happened to people saying Marceline used to be human? If her mom and dad are both demons then it is very unlikely that she used to be human? ƒelinoel. 00:54, April 27, 2012 (UTC)

Well after it was revealed her dad was a demon and we don’t know what her mom was/is. It’s safe to assume she’s not human or at least fully human. I mean look at her skin when we see her as a child. Her skin is almost white. Her ears are also long and pointed like her dad’s. She doesn’t look fully human to me. And it’s not like Marceline’s dad isn’t truly her dad and some one else is. I mean she resembles him and it’s been proven he has spent quite of his life with her. Given by the episode "It Came from the Nightosphere" “ and this picture from the extended preview.

If one of my parents were a demon and my other wasn’t, just by scientific law and genetic order I wouldn’t be pure human. Nor would I be a demon. I’d be a hybrid, a new species. Who knows, maybe she is human. There’s a chance I could be wrong. But from newer episodes and information, maybe that is why no one talks about Marceline being human. And no if both parent’s were demons, I doubt it could be possible for her to be human.

I also posted another picture of Marceline from the extended preview to show off the “extremeness” of her ears.

How do we know Marcy's mum liked the Lord of Evil? Deals with the devil aren't uncommon. Marceline the Radical Dame 05:34, April 28, 2012 (UTC)

Oh, I like your thinking. I didn't think about it that way. Hhhhhm well that would any interesting part to see in Marceline’s story, but I don’t know if Cartoon Network would allow that story/situation to happen. I say that because maybe very religious or touchy parents would find that wrong or “evil”. Because you know the devil is “bad” and making deals with the devil is “bad”. There for maybe those parents would find it bad for kids to exposed to that. I don’t know if that would happen, it was just a thought of what could happen if the story went that way.

And if that was their idea for explaining how Marceline’s parents came to be, Cartoon Network might want to try to avoid that whole “possible” confrontation. But If I’m wrong please correct me, because I’m not sure if the Adventure Time Team would be allowed to show that “story/situation”. (making a deal with the devil)

Anyway is Marceline’s Dad the devil? He is the Lord of Evil, is that the same thing as the devil? I’m not sure. This is just my thoughts. Anything is possible until they actually show what happened. When ever that will be.

Marceline killed her King this is why she is Queen. So she may have gotten the idea from her parents, her Dad may have killed her Demonic mom. (same bluish skin tone as her father) Also, why can't Marceline be adopted? And then be turned into a vampire after the Mushroom War. Not knowing about her mom because her mom has already died. Just a thought. --27finsprincess 15:00, May 12, 2012 (UTC)

You point out good points. I haven't thought about it that way and anything is possible. Too me though, I'm not sure if Marceline's dad killed her mom/his wife/partner. I say that because he seems to be a family man (in his own weird and confusing way) but he is the Lord of Evil so that makes it hard to say. Anyway if he killed her mom wouldn't that have caused major major daddy - daughter issues? Worse then eating her fires?

She could be adopted but when she was younger she bared traits that resembled her father, she didn't look human. It's mainly her ears and her skin color that makes me say that. FootBall 10:54, May 14, 2012 (UTC)

It could have been that Marceline and her mom were humans, because of the bite mark on Marceline, Marceline should have no Bite marks if both of her parents are vampires. Anonymous--(UTC)--

Another theory I have is this: what if Marceline was just a normal girl at first? She had no bitemarks as a kid and not as a teen either. Maybe when she was around 18-21 she was bitten and turned into a vampire by the Vampire King, who fell in love with her. She didn't really like him back though, and being the radical dame she is, she killed him and became the Vampire Queen herself.

But since I haven't seen that many vampires yet, she didn't have much to do so she used her powers and her deathlessness to travel around the world and have awesome adventures instead of ruling over the other vampires. I don't think they have a kingdom like the candy people do anyway (I think they aren't very origanised and pretty much on their own), so she had all the freedom in the world.
Maybe Marceline didn't even kill the Vampire King, maybe she married him out of rebellion against her dad because she knew he would disapprove. For all we know they could have been perfectly happy together, but then he had an accident and he fell off a cliff or something. Marcy then told everybody she pushed him off because that would make her sound pretty cool. She has been known to lie or brag sometimes but she doesn't really come across as super evil so why would she kill him?
Now about Marcy's mother, I think she may have left Hunson Abadeer when Marcy was still very young. The only pictures I see of the family together are very vague but it looks like Marceline is still pretty young. Maybe she does not know her mother very well and they are somehow estranged. And maybe she blames her father for leaving, who knows? That could be one more reason she had issues with him, besides the fries. :)
Just a theory, maybe I'm completely wrong. Marcaline 08:29, May 25, 2012 (UTC)

Well it has been established that she hasn't always been a vampire. But to me she must know he mother enough to have memories oh her, as she stated in Henchmen. Ever one free to their own opinions though.FootBall 017:57, May, 2012 (UTC) Guys, the answer to this is obvious: Marceline. The Vampire. Queen. Her dad is the Lord. Of Evil. That would make her the Lady of Evil. But she calls herself the Vampire Queen. How does that compute? Well, when a Queen dies, the Princess becomes the queen. The vampire queen. Marceline's mom was the vampire queen. Notice how I said was. She's either dead, or forced Marceline to marry the Vampire Prince so she could get out of her Queenly duties and go Lolly-gag somewhere else. Or I could be completely wrong and Marceline just calls herself a Vampire Queen cause she thinks it's cool. 67.142.178.22 21:04, June 1, 2012 (UTC)

Well I'm sure idea/ thread is dead, but if people still happen read this, that’s good. I wasn’t sure if I should start a new thread to say this or keep it in this one. So back to the point. I want to take back about what I said about Marceline never being human. Recently I got the 4 issue of the comic and there is a page that isn’t up on the wiki. Her skin is actual normal colored. (though it’s hard to tell in my picture, but it is) (I’m sure/most some people are aware of this page of the comic, though I’m not sure why it isn’t up here)

Notice how her ears are normal too? But later on they get longer and her skin changes to more like her father. (View earlier pictures) My two theories: Radiation or as she gets older she changes to more like her father? --FootBall (talk) 04:52, July 20, 2012 (UTC)

@football and everyone else, she can change her appearance --YEAH! LOLWUTBURGER! YEAH! or you could just call me lb. 11:56, July 20, 2012 (UTC)

Yes she can change her appearance, but that is because she is now a vampire. Though last time I checked she wasn't a vampire as a kid. --FootBall (talk) 16:28, July 20, 2012 (UTC)

I always thought Marceline's mom must be some kind of angel, for some weird reason, It would make sense, somehow; also, noticing the photo, maybe that's not her biological mother, she might be a surrogate, and that's why she don't like to talk about her... (Mackaber (talk) 07:47, July 24, 2012 (UTC))

Well that could be quite possible, in theory. (I say that because we don't know whats true yet.) I mean there’s the Lord of Evil, demons, Death, so there’s a good chance there’s angels. To me it seems weird that an Angel and the Lord of Evil would bare a child together. You know, an angel represents good and the Lord of Evil represents Evil. Unless if her Mom was a fallen angel. --FootBall (talk) 18:52, July 24, 2012 (UTC)

I really like some of the points Marcaline made above... But I personally think that while Marcy's dad was a demon, her mom was definatly either a human or vampire. If she was a human, I think that her mom must have met an end during the GMW and then she was turned later by the vampire king. While, again, it wouldn't be impossible for her to have married the vampire king... I think it would have more likely been an aranged marage, as Marcy is way to much of a radical dame to get married. (For example, we can assume that she was with Ash, another immortal, for quite a long time. This can be seen since he was with her in both the treehouse and her newer house.) So she probably knocked him off when he restricted her too much with Vampire Queen responcabilities or some such.

The second option is that perhaps Marcy's mom was a vampire herself. This would have made Marcy a half demon half vampire. But how would this have been possible when she was clearly not a vampire when she was young? Mabye it was because she was a fledgeling vampire when she was young, then was bitten by her mother later on. This would have meant that she could have inherited the title of vampire queen from her mom (and killed the king later becuase she never asked to have him be her king). Why would she bite her? Mabye Marcy's mom was aware of the incoming danger of the GMW and bit Marcy to make her a full vampire to help her survive. Perhaps as a result she is subsiquently weakened by turning another other person into a vampire, and is vunerable enough to be killed by the GMW. Mabye this created a bit of a tear between Marceline and her memory of her mother, because Marcy was mad at her mother getting herself killed and leaving her alone with her father.

All speculation though of course... who knows? Can't wait to see what the AT team do with her character next! (As long as we don't get more episodes like Daddy's Little Monster...) ---M TheVampireKing (talk) 01:16, July 28, 2012 (UTC)

In the family portrait, the person that Hunson is standing next to is a male child...not a female child. Take another look. He has short hair and is wearing a pointed cap (a party hat, a clown hat, or a dunce cap). I'm betting that this is Marshall Lee, who will not only turn out to be Hunson's son, but will also be Finn. Finn will be his Ooo identity. The female in the portrait is probably Hunson's eldest daughter whose Nightosphere identity has not yet been revealed. She will probably turn out to be Princess Bonnibel Bubblegum. This will be her Ooo identity. The gap between the two children in the portrait is probably where their mother would have stood if she were still alive. I believe that Hunson may have eliminated her. Read the forum "Watercooler" comments under the "Sons of Mars" episode to understand Hunson's likely life philosophy (male domination). Marshall Lee, the Vampire King, is dead only in the male domination sense. In other words, he rejeced Hunson's life philosophy, just like Marceline. It is unclear what Bonnibel's stance is toward Hunson. Marshall Lee, and possibly Bonnibel, were probably close to Marceline. This probably had Hunson furious. Marceline fought to preserve Marshall Lee's heroic qualities to prevent him from being a manipulated, order taking male. She probably also fought to free herself and Bonnibel from being enslaved, servant girls. Notice that Marceline is not in the family portrait with everyone else. She's on a separate wall. In the same vein as others have mentioned above, she is probably not the birth daughter of Hunson and what will likely be his deceased, former wife. She is probably the deal that Hunson cut with the devil to get ahead in life. It does not appear that Hunson's two children have any awareness that Marceline is not their real sister. Marceline's situation has something to do with the Ice King character. She has had no scenes with the Ice King thus far. In the "Holly Jolly Secrets" dual episodes, Marceline was outside the window and not inside the treefort with everyone else. Ice King imitated her "Fry Song" in the same episodes, but he may have only heard the song and may have just grabbed a black wig that he had on hand to amuse himself in the video he was making. Was she one of Ice King's stolen princesses...a human trafficked infant girl? Based upon the Ice King's video diary in "Holly Jolly Secrets," the Ice King may be 6 different men caught up in Marceline's trafficking and subsequent placement with the Abadeer family. Notice how the video cuts out 6 different times. If he's 6 different men, this explains his inconsistent and erratic behavior that many have mistaken for Alzheimer's disease or lying. One is named Simon Petrikov. One is an antiquarian who came in contact with, or found, his crown. One may live or work near an airport. One has a female companion (relative or friend) who is a doctor. Two of the men have someone they loved named Betty, one of those men purchased his crown in Scandinavia. Is Marceline shapeshifting to become Gunter, the one penguin that stays close to Ice King? Based upon the Nightosphere portraits, Marceline is the youngest child although she appears to be the oldest in the Ooo scenario. I think that the three children were in an abusive household and that the Land of Ooo was Marceline's childhood, imaginary world for the three of them to hide in and thrive in. I think that the "memory crack" in "Memory of a Memory" was a skull fracture that Marceline sustained as a child at the hands of Hunson. Marceline gave the two other children a new appearance and identity in Ooo so that Hunson would not recognize them in her perfect world. Marshall Lee's Nightosphere past was erased entirely and he was raised from birth by heroic dogs as "Finn Human" in Ooo. This explains the romantic resistance from Bonnibel to Finn. It is unclear what Bonnibel's situation is. She seems to know Marceline well. I'm betting that Bonnibel knows that Finn is her brother, but she has not mentioned Hunson at all. Marceline would have to maintain contact with Hunson in order to keep her Ooo utopia intact. It looks like problems are brewing in Ooo, though. Notice that the Peppermint Butler is also Hunson's golf caddy as shown in a portrait in his entryway. Peppermint Butler is also friends with Death. I think this is why Marceline probably drove Finn and Jake to take over her old treefort in "Evicted." She needed to have a reason to quietly move back to her old cave to be closer to Bonnibel and monitor the situation in the Candy Kingdom.--71.53.175.73 03:21, August 13, 2012 (UTC)

I'm pretty sure that is Marceline in the picture, she had short hair as a kid. Also when people have kids they tend to have more then once picture of them around the house, not just one. --FootBall (talk) 04:40, August 21, 2012 (UTC)

@FootBall I agree. Other dude, Most parents have pics of their children by themselves ESPECIALLY if they are an only child. Why can't Marceline just have her hair tucked into a cap? And why can't Simon/Ice King travel alot? Why does it have to turn into a crazy conspiracy theory 71.185.80.58 03:42, August 23, 2012 (UTC)kitty

Females don't tuck their hair into pointed-style caps, for starters. Even with Marceline's shorter hairstyle as a child it would be unlikely that her hair would fit inside this particular cap. I'm certain that it is a male child. Look at the neckline. It looks like the child is wearing a boy's dress shirt and possibly a red tie. The photo is cut off so you probably cannot see that he is wearing a suit much like Hunson is wearing.--76.0.239.201 08:03, August 29, 2012 (UTC)

Marceline has been shown to have a lot of different styles, so she could have been a tom-boy for some of her life, and almost all hair can be tucked into a cap. If it shorter then the end of a cap then it is all ready in if it is longer then a end of a cap it can be tucked in. That's besides the point though. I'm sure that is her hair line her head and ear. It's such a small picture with little detail. I'm not sure why/how you are getting all this information from it. A dress shirt and tie? Did you forget that Marceline wore an overall/dress when she was younger. All most all clothing give off similar necklines.

Also Marceline and Hunson has never stated to have a brother/son. And Marshall Lee is a Gender swap of Marceline, (not a brother) they don't exist together in the same universe. --FootBall (talk) 22:37, August 30, 2012 (UTC)

You with the crazy long theory--really??? You've got to be kidding. You're digging WAY too deep here. I've been reading this Wikia for a LONG time and I have never read ANYTHING dumber. I don't mean to offend, but seriously dude...back up and take a look at what we already know. You can theorize a lot from that, but not this much! I don't like to think of Adventure Time of too much more than it is. So just stop and think next time. MusicPrincess7 71.246.91.167 22:16, August 31, 2012 (UTC)

I doubt that if Ice King was singing Marceline's song, the black wig was a coincidence, especially because after he finished, he said something about how Marceline's songs are so good. I haven't seen the Holly Jolly Secrets episodes, but the time I HAVE seen Ice King singing, his train of thought is directly tied to Marceline. BreTheFirst (talk) 18:20, May 20, 2013 (UTC)

Maybe the witch in the episode "the witch's garden" is Marceline's mom=) —Preceding unsigned comment added by You do not have permissions to kick a user (talk • contribs) . Please sign your posts with ~~~~

Marceline's mother is indeed one of the many mysteries that surrounds Marceline's past. There is some information we can gather by things said or seen in the show that may be able to shed further light into this mystery. Here are some of these clues and my interpretations of them:

1) Young Marceline has pointed ears. We all saw in "Memory of a Memory" that she had pointed ears during her youth, before the land of Ooo became what it is today. This tells us that Marceline is not human, at least not entirely. We have no proof for or against her being a hybrid species, however, so the most that we can gather is that she is probably not human. So, by extrapolation, we should assume that Marceline's mother was not a human either. Some one above gave us a picture from the comic of Marceline with pointed ears. However, I believe it is stated in this wiki that the comic is non-canon with the show and any information given there cannot be used in any certainty.

2) Marceline's skin color. Young Marceline's skin is not the same shade as her father's. This can also be seen in "Memory of a Memory." Even in the present, her skin is still a fair deal lighter than Hunson's. However, you may not have noticed that her skin has darkened since she was a child. Perhaps it is normal in the Adventure Time universe for a demon skin to be much lighter in youth than in adulthood. We do not have enough information to come to a conclusion with this observation as to the species of Marceline's mother. However, you can see in the family portrait in "Return to the Nightosphere" that Marceline's mother has the same skin color as Hunson. This would lead us to assume the they are of the same species, that being demons. The seemingly random shuffle of chromosomes during reproduction does lead to phenotypes not expressed in the offspring's parents. This could explain the difference in skin color between Marceline and her parents. One other possible explanation is that Marceline's vampirication changed her skin color, but we have no evidence to support this as we have seen no other vampires in the show. This information still does not give us much information regarding Marceline's mother other than that she is probably not human.

3) Marcelin's mothers appearance in the family portrait. In the portrait, Marceline's mother looks much like Marceline does now, albeit with skin color closer to Hunson's. This leads us to believe that she is the same species as Hunson. Although, the picture is lacking any great details so we cannot gain much other information aside from this and the information stated in point four.

4) Marceline's mothers position in the family portrait. Marceline's mother is standing off to the side of the portrait with Marceline and Hunson on the other side. While this could mean nothing, it could also signify a strained relationship in the family. What that strain is exactly, we can only guess. With Hunson and Marceline together we can assume they as still close at this point. Marceline's mother could have a strained relation with both Hunson and Marceline or just Hunson or Marceline. If her problem was only with Hunson, she could have tried to leave with Marceline but Hunson, being a more powerful demon (especially with the amulet), could have kept Marceline with him and forced Marceline's mother to flee.

5) How Marceline speaks of her mother in "Henchman." In the episode, Marceline speaks with seemingly fondness about her mother. Based on the information given in point four, we can assume that Marceline did not have an issue with her mother. If there was an issue, it would have been between her mother and Hunson. This means that either Marceline's mother left them or she died. We cannot say for certain.

In conclusion, the evidence seems to point to Marceline's mother being a demon and either left the family or died sometime after the portrait was made. - Alchemical (talk) 21:18, October 3, 2012 (UTC)

Ha, thanks for summing all that up. I wasn’t going do it because I thought it was pretty evident what people were talking about and what this thread has established. Though people should still feel free to continue on add their ideas and what not to this thread if they so please. --FootBall (talk) 22:47, October 3, 2012 (UTC)

Oh, my gosh. I can't wait for there to be an episode on Marceline's mom!

Since the recent episode, it's safe to say Marceline is vampire and is also half demon. I'm assuming she's half human too. Though that isn't confirmed, it's pretty safe to say. What, is she half fish too? Don't think so. It's nice to know something new for once about her. --FootBall (talk) 00:55, November 13, 2012 (UTC)

I also just saw the recent episode. Marceline is confirmed 'half-demon', meaning her mother must be human. Her mother can't be vampire, or Marceline would be immortal (and not age like in the alternate dimension) nor does it explain her lack of marks as a child, and then them appearing later with Ash. --Nonukez (talk) 03:17, November 13, 2012 (UTC)

I couldn't read through all the craziness(plus the font is small) but I just want to say maybe she had an imaginary friend. She was at the age and probably wanted him/her to be in the picture. 98.111.142.217 04:07, November 13, 2012 (UTC)

In farmworld she is only half demon and aged. Meaning the death of Simon somehow prevented her from turning into a vamp. My theory is that she got turned then returned to her family leaving Simon who was now fully crazy. This would explain why her mom would patch her up after she got in the sun. This could mean she was with her parents during her juvenile vampire years. Her Mom is probably now dead but not because of the war. This is because she was around through some of Marceline's vampire years. She probably moved into the nightosphere with Marceline's Dad during that time the picture was taken. She probably died of Old age or a sickness. Due to the fries incident they probably returned to earth after her death. Also due to the existence of avampire king there were other vampires.Azikiwe17 (talk) 03:57, November 15, 2012 (UTC)

Interesting theory, but when she was a teenager during the fries incident, she didn't have her bite marks. She wasn't yet a vampire then.

Here's my theory, and hopefully it connects everything (if I missed something or my info isn't correct, let me know). In "Finn The Human," it's been established she's a half demon, which is very strong evidence her mother's a human. In "I Remember You," when Simon first runs into her, she seems to be mouthing "mommy" while she's crying. What I get from this is that her mom either died due to the war, as she is just a human and couldn't survive. The family portrait must've been taken before the war, and Marceline's fondness of her mother and her mother picking her up when she scraped her knees all must've occurred before the war.

The same scene in "I Remember You" must be very soon after the bombs hit. This is further evidenced by the fact that Simon looks identical in that scene compared to in "Finn The Human" when he's stopping the bomb from exploding; same clothes, same beard, etc. In the real timeline, he wasn't able to stop the bomb, and right after it hit and destroyed the city (and killed Marceline's mom), he went looking around for survivors and ran into Marceline.

Whatever the mushroom war did, it led to the events of her turning into a vampire. This part of the theory is based on a lot of speculation and not too much evidence, so bare with me. I'm assuming that it was due to the mushroom war that Hunson roamed the earth. I don't think that he'd be walking in the city while it was still inhabited by millions of people. This would explain why Marceline didn't become a vampire in the alternate timeline; the fries incident never happened. So in the real timeline, the mushroom war happened, and the fries incident occurs with Marceline. Again, she still does not have her bite marks here. We see later that she's with Ash, and at this point she does have her marks. What I'm guessing is that, since she's just a young teen during the fries incident, she ran away from home and met the badass boyfriend. Typical teenage scenario; hanging with the wrong crowd, being rebellious. Whatever they did together (again, stupid teenage stuff) included her becoming a vampire and killing the vampire king.

Hmm, now that I think about it, maybe her dad and her mom were divorced? This would explain the family portrait, and the distance between them is because of the parents and not Marceline and her mom. This would also explain why Hunson wasn't present in "I Remember You," and why Marceline was calling out for her mother. A joint custody situation, where the parents take turns spending time with the kid. Very common. She could've been with her mother when the mushroom war occurred, which would explain Hunson's absence. I apologize for the long post. Hopefully someone will take the time to read it.

when marceline was born she was half demon and thats why she survived the mushroom war explosion or when the explosion happened or before it marceline dad bit her. But being half demon is shown in the episode "Finn the human" where she tells one of the charcters she is half demon. Her mother could possibly left them, died, or is hiding or vacationiing somewhere in Ooo180.194.244.204 23:19, April 12, 2013 (UTC)

First off: why do people think Marcelline's dad bit her? He's not a vampire in the first place. 

Here are the facts so far, let me know if I've missed any:

Marcelline is a half-demon, or at least her farmworld counterpart is. She clearly isn't pure human, as shown by the blue skin, pointed ears, and fangs she had even before being bit.

At some point, presumably young adulthood, she was bitten by a vampire. Notably, the first time she is seen with bite marks is also the first time she is seen with Ash. Perhaps he was somehow involved in her getting bit, perhaps not.

Photos of young Marcy with a blue-skinned woman are seen on several occasions. This might be her mom, although it would be strange if her mother had blue skin but wasn't a demon. Maybe her mom was some other non-human entity such as a vampire, or maybe the woman in the picture isn't her mom at all.

Marcy was on her own when Simon found her. Her father was probably bound to the Nightosphere, like he was before Finn released him in It Came From the Nightosphere. Her mother's whereabouts at that time are unknown, however if she was human it is likely she died during the Mushroom War (perhaps Marcelline only survived because of her demon blood). If she was not human, maybe she was also stuck in the Nightosphere or maybe she "ran off" or goes missing for some other reason.

I find it unlikely that both of Marcy's parents were bound in the Nightosphere, because she was in Ooo. What kind of parents would drop their 7-year-old daughter in a post-apocalyptic world with no one to care for her? So I personally believe Marcy was in Ooo with her mother while Hunson was bound in the Nightosphere. Then, during the war, either Marcy was separated from her mother, or her mother died.  Personally I think this is the most likely.

One more theory though, maybe her mom was bitten by a vampire shortly before the Mushroom War and left Marcy because she didn't want to hurt her. But later on she tried to find her daughter and that's how Marcelline ended up getting bit years down the road. That would be nice because they would be able to reintroduce the mother as a character, either in flashbacks or as a new character during Finn's timeline.

Hmmm, blue skin. The only other characters I remember with blue skin are the Ice King and some candy people. Just saying. BreTheFirst (talk) 18:23, May 20, 2013 (UTC)

Family portrait Edit

Has no one considered that the gap in the family picture is because of some sort of vampire relative who was standing there, but didn't show up on film because, ya know, vampires don't show up on film? Maybe Marcy or even Marcy's mom has/had a vampire brother who was in the family portrait. It's also possible Marcy mom was human, and gave her life to save her 2 vampire children, i.e. to feed them, prior to discovering that they really only needed to color. Just a thought. 192.222.31.4 16:42, May 7, 2013 (UTC)

You just blew my mind with the vampires not appearing in pictures thing. Maybe Marcy's mom was a vampire, and was standing right next to Marcelline but didn't show up in the picture because she was a vampire, and the girl standing a couple feet away is someone else entirely (a sister or a maid)?  

I guess the question is, has vampire Marcelline ever appeared in a picture? If so, this theory is bunk...  OpusGlass (talk) 00:07, May 24, 2013 (UTC)
