- In The Adventure Time Encyclopædia, Hunson Abadeer said that even he doesn't remember his own origins, as he has existed since before time and before everything, when "there were only monsters" like Orgalorg, indicating that he might be a Deity, though it hasn't been confirmed in the show whether or not this is true.
