Me-Mow

Me-Mow is a villain on Adventure Time. She's a very tiny cat and is an assassin. She becomes the main antagonist in the episode Jake vs Me-Mow, when the heroes Finn and Jake visited Wild berry Princess she told them that she have been targeted by a organization of assassins. Me-Mow was sent to kill the princess possibly because of her stealth and size and she needed to pass a test to become a full assassin or else she had to retake the next year. When she was hiding in a pie she is found by Jake and then she uses him as a slave (while hiding in his nose) to kill the princess or else she will eject him with poison. When Jake failed twice to kill she ejects him twice, then she reveals herself to Finn. When Finn and Me-Mow fought she already destroyed the antidote for the poison, Finn knew it was all over so he couldn't keep fighting, saying his last goodbye with Jake they realized he can stretch twice is size plus one so the poison wouldn't travel travel (right when Me-Mow said the poison can kill a dog twice is size). She fails, but her anger lashed out and she attacked the princess,she missed then fell down a cliff that was meant to be the princesses death. In the end it is revealed she didn't fell all the way and that shes on top of a bird, it could possible she'll comeback to kill both Finn and Jake so they won't inter fear here missions.
