i could never be my own favorite anything don't worry, UHHH THIS IS A TOUGH ONE... i haven't engaged with enough shows or games or medias with bunnies in them to have a good answer, i'm more familiar with people's sonas, i've been thinking on this one for like 3 days now...

i think maybe Vibri from Vib-Ribbon is the perfect fictional bunny IMO. simple, iconic design you could put anywhere & recognize instantly. like That's Vibri. hands down. + she's so cute & has a pretty voice & can do anythingg. like c'monn

here's where i'd start listing a bunch of folks/friends bunny sonas & ocs but i'm deathly afraid to forget any so you'll simply have to keep a close eye on my reposts & reblogs lol
