During the early development stages of Big Hero 6, Disney animators had to figure out how each of their main characters moved. So they made these test animations to study each character’s movements, and how those movements reflect their personality.

The animators were given a deceptively simple task: have each of the main characters walk into Aunt Cass’s cafe and sit down. We get Baymax with his baby penguin-inspired waddle. Hiro’s movements were inspired by one animator’s teenaged brother. Wasabi is extremely deliberate in each of his movements, while Honey Lemon is bubbly. This exercise is actually where GoGo Tamgo’s bubblegum chewing originated. And Fred, well, he’s just an excited goofball.
