Fluffy is your average Haredonian rabbit who just wants to live his life. Unfortunately, the world he lives in has other plans. He can be seen as a bit grumpy, un-heroic, and possibly even antagonistic, but deep down he's not a bad guy, just someone who accidentally swept himself into adventure and regrets it.

Bill is a comedian from Foxas. He befriended Fluffy after insulting Jackie, though he ultimately regretted the insult to the point of inviting her to come with them to Owlberta. Like many who crack jokes, however, he's not very good with being on the receiving end of them.

Jackie (aka Wonder Cat) is a 20-year-old cat from Kittsburgh. She loved superheroes growing up and now dreams of becoming the greatest one ever. She's the one who's the most optimistic about the long journey and the obstacles, even though her naivete might cost her everything, including her life.

A mysterious white tiger solely known as "The Tiger Wizard" is the main antagonist of the story. He wields a magic staff that can cast any spell he wants, such as turning people to stone, or creating a dragon. He doesn't take crap from anyone, and if someone does him wrong, his revenge is inevitable...
