Erasem anime.png

Erasem (Boykyakku in Japan) is a Demon Beast found in the Kirby: Right Back At Ya! episode "Escar-Gone". She first appeared when Dedede ordered her from Nightmare Enterprises, expecting a super-powerful Demon Beast, but instead ends up with a small ghostly creature. She then goes into Escargoon's room and enters his body while he is sleeping. The next day, Dedede, or anybody else does not remember who Escargoon is. Strangely, Kirby can remember him (it is implied that his uncontrollable brain power makes him unable to get amnesia). It is then revealed by Meta Knight that Erasem has the power to make everybody forgot who the one that she possesses is and that the only way to get Erasem out is to torture Escargoon. They succeed, but Erasem goes to Cappy Town and is about to possess somebody else. Kirby inhales her, and everybody forgets who he is (even the iris transition at the end, aimlessly searching for something that it could close on in. Kirby then spits out Erasem towards the screen (thus breaking the Fourth Wall) and Erasem exclaims "Bye Bye Kirby!". It is unknown what happened to Erasem after this.
