Great anime characters can take literally any form. From school kids to slimes, the heroes and their sidekicks can look like anything and everything. Anime has a number of companions that aren't human but bring something to the table that is truly one of a kind.

Some of these companions are cute animals that help the protagonist in their quests or out of trouble. Some of them sit back and watch the story go by while amusing themselves with their own wacky antics. A fair number of these companions aren't even human. Whatever species they may be, an animal (or otherwise) companion can add much-needed humor or boost merchandise sales.
