Sir Slicer

Sir Slicer is a Villain from Adventure Time Universe.

He is probably one of the evilest Adventure Time villains, cause he made Finn nervous and miserable.

He wants revenge on Finn for making fun of his armor and copy his quote.

He joins Phobos to get Finn but Phobos told Slicer that Finn's new friends,The Helper Squad, makes fun of him even worse. Slicer shall kill them then Finn and his friends.
