Bear

The Bear is a major character in the episode "In Your Footsteps." After Finn saved it from choking, the Bear followed him and Jake to the Tree Fort. It tried to copy Finn because it wanted to be a hero. Finn gave him the Enchiridion instead, which the bear later gave the Snail, who is possessed by The Lich.

Appearance
He looks exactly like a normal bear with brown fur. At some point, he wears Finn's clothes and a poorly made mask that is supposed to resemble Finn's face. He can talk or mimic talking and can write, but he writes the letter s backward and isn't a good speller.

Personality
He has demonstrated a calm personality and not a very high intelligence, believing that copying Finn, he automatically would become a hero. However it is unclear to say if this is his true nature, due to his connection to The Lich, as he could have concealed an evil personality or even being deceived, for he has not shown a change in attitude when he encountered Lich however, He might be controlled like how the snail was controled to pen the Liches prison.
