Here is Ezra, Ruby, Shadow, Sabine, Chopper and Kanan in a half wolf form and how they look like
Ezra
(couldn't find the right outfits)
Ruby
Shadow
Kanan
Sabine
(she was a bit hard because of how colorful she is. She would have marking in her wolf form)
Chopper
(As a human)
Hera and Zeb might be hard but would you like me to try?
