The Evil Monkey, also known as the Finger Monkey is the former hated pet of Chris Mcfinnigan that used to live in his closet.
Starting as early as "Dammit Janet!", The Evil Monkey lurked in Chris' closet and became his nightmare monster. In the middle of the night, The Evil Monkey would bust through the closet doors and dramatically point at Chris in anger. Chris lived in endless paranoia of that thing and often couldn't sleep and didn't even dare enter his closet. Chris' parents, and everyone else around him never believed his stories about The Finger Monkey, so none of them did anything.
In the episode "Hannah Bannana", Chris finally proved the existence of the Finger Monkey to his family by manning up, entering the closet, beating the snot out of it, tying it up, and dragging it's mangled, restrained body to the living room. Much to the astonishment of his family, the monkey was real and they sure felt silly. When the monkey retained conciousness, he got the chance to explain who he was. As it turned out, The Evil Monkey was actually a good guy, who only wanted to be friends with Chris. The two of them soon bonded and lived with each other like father and son, much to the jealousy of Peter. Their friendship eventually caused a rift between Peter and Chris. Eventually, The Finger Monkey had to leave, and he abandoned Chris, never to return again. Except for multiple times later.
In "My Little Brother", The Finger Monkey comes back in town for a visit to teach Chris how to stop being a Brony.
In "Chris Has Got a Date, Date, Date, Date, Date", Taylor Swift sang a song called The Boy in the Giant Tux, about an annoying boy she dated named "Chase Gifford", a not-so-subtle stand in for Chris Griffin. One of the things she mentioned "Chase" doing was talking about a chaotic neutral panda who lives in his closet. This is a loose parody on the evil monkey who lives in his closet.
