Shoko was the name of one of Finn's past lives. Many, many years ago, she and her companion roamed the lands of Ooo. According to her, she was mutilated and abandoned by her parents at a young age, which resulted in her taking the path of a common criminal. She supposedly only has one arm because her parents sold her right arm for a computer before dropping her at a dojo to give her fighting skills. Her parents never returned to the dojo; thus, Shoko was left without any parents or guardians.
Shoko first appeared in "The Creeps" as an amorphous ghost with long, green hair. She scared Finn while he was hiding inside the Castle. Shoko, in her ghost form, made another appearance in "King Worm," when Finn unleashed his subconscious fears to escape his dream. A picture of Shoko in her ghost form was also seen in "Sky Witch," in Maja's house.
In "The Vault," Jake had BMO hypnotize Finn to recall memories he was suppressing in his mental vault. This caused Finn to have a vision of the past, seeing Shoko and various objects. She was under the employment of the Bath Boy Gang and took on jobs for them. Her most recent job was to steal Princess Bubblegum's amulet. In order to get the amulet, she spent some time befriending the princess, but then when she was given a new mechanical arm, Shoko became conflicted on stealing the amulet. Fearing for her life, she later stole the amulet when Princess Bubblegum was asleep.
With the amulet in hand, she fell into a river of toxic waste and was mutated by radiation into a slug-like amorphous creature that was seen before in previous episodes. She then crawled up to a hill, in front of a tree sapling, and died. On that very hill, Finn's future tree house grew, where her corpse was in the branches, holding Princess Bubblegum's amulet. This amulet was returned to Princess Bubblegum by Finn, who was then given a thumbs up by the ghost of Shoko, no longer mutated.
In her former life, she was a humanoid who was notable for having one arm, the other being removed to be sold for a computer. She had long, black hair about knee-length, lime green skin and bright yellow eyes similar to that of Farmworld Finn. She also tried on a mechanical arm like he had. Her outfit consisted in a gray dress and flats and a teal scarf.
Shortly before her death, she was mutated by being knocked into the radioactive river beneath the Candy Kingdom, turning her into a slug-like creature with two arms, the second grown back through her mutation.
Shoko seemed to be very responsible for her age, but due to her parent's neglect and her lack of a proper upbringing, her views on morality and her common sense were warped. Due to all this, she took on the life of a thief and did not appear to see anything wrong with it. She began to feel regret when she befriended Princess Bubblegum for the purposes of stealing her amulet, especially when she was given a mechanical arm by her as a gift. However, to save her life from the Bath Boy Gang, she still stole Princess Bubblegum's amulet, but this decision was averted by making Finn return the amulet on her behalf.
Shoko was a skilled fighter/thief, and even though she had only one arm, she was very capable. This is further proven by demonstrating that she can still fight and carry buckets with little to no trouble. She also seems to easily work her new mechanical arm, even with the short amount of time she possessed it.
As a ghost
As a ghost, she was a large slug-like creature with long, green hair in the Castle with Finn as he was hiding. Shoko came out through the wall and gazed at Finn as her hair slowly filled the room. Finn broke through the wall to the next room to escape from her, thinking that she had killed all of his friends and that she was after him too. He later found out though that the party was just a prank by Jake and that Jake had no clue who she was, that he must have imagined it. He then decided to forget the experience by putting it "in the vault."
Shoko, in her ghost form, made a reappearance in "King Worm" when Finn unleashed his subconscious fears to escape his dream. This reveals that although Finn put the memory of her "in the vault," he is still subconsciously afraid of her or at least of his memories as her.
This form has light grayish-blue ethereal skin with scale-like lumps and long, green seaweed-like hair. Her neck is unusually long. Her scales are light blue, her irises are black, and her pupils shine red. Interestingly, her appearance differs from the most of the other Ghosts in the series, who are all less colorful and more smoothly shaped. Even her ghost shape appears mutated. Her design is also similar to a Japanese style ghost. This form is a result of falling into the toxic river that once flowed through the Candy Kingdom, but had yet to be contained or neutralized. Upon being immersed, a newly formed Gumball Guardian attempted to rescue her, but the waste proved too noxious for their bodies within the seconds they attempted to fish her out.
Shoko phased through a wall, which was preceded by a ripple effect on the space and a humming sound. Her green hair grew to fill the library that Finn was hiding in, as if trying to reach him. She seems to be able to take possession of items, or produce hallucinations.
- Shoko and Farmworld Finn both are missing their right arm.
- "Sky Witch," what seems to be a framed picture or painting of Shoko's ghost form can be seen in a pile of stolen objects, while Princess Bubblegum explores Maja's storage room. Seconds later, in a different shot, Shoko's painting's expression suddenly changes, seemingly becoming more creepy or menacing. This was speculated to be due to the painting being sentient, possessed, or otherwise animate. However, artist Derek Hunter has confirmed that this was a mistake due to two different drawings being mixed up somewhere during production and that only one of them was meant to be shown in this scene.
- The robotic arm that Princess Bubblegum gifts to Shoko has similarities to Finn's robotic arm seen in "Finn the Human," "Jake the Dog," "King Worm," and "Puhoy."
- This continues the trend of alternate versions of Finn, except Fionna, having artificial right arms.
- Also like Finn, Shoko had an animal partner, except it was a normal white tiger, instead of a magical dog. The tiger was stated offscreen by Jesse Moynihan to be a past life of Jake.
