I guess when an idea has been floating around in my head since 2006, there has been a lot of changes.
2006 version:
Mr. Blueberry:
Wrapped from head to toe in bandages to cover his odd purple skin. He as a giant asshole. He used to go around torturing people but turned his life around and became a teacher/father.
Ken Kumo:
A troublemaker and social reject. He was bullied a lot in school for having Fire-Magic and was transfer to Frostpeak.
Bertie:
Clone boy who lived with his older sister. His mouth was sewn shut and had to talk to people telepathically. He hated Mr. Blueberry for causing him trauma.
Ace Kumo:
Ken's dad who was missing fro several years. He was apparently running from the feds which ended him up in prison. He was able to reunite with his son. There was one version of him where he was Ken's brother pretending to be his dad.
Zeta:
A uppity pure-blooded Fire-Person. He was asexual and very grumpy and critical of everyone.
Current Version:
Mr. Blueberry:
He's a lot nicer yet is still rough around the edges. I ended up removing the wrapping (something I decided years ago because it was impractical). He's less insecure about his skin condition. He is very bright yet can sometimes comes off a bit low brow. Mr. B is far more queer coded in this version.
Ken Kumo:
Pretty much the same but he has Air-Magic instead of Fire-Magic. But he is very fascinated by fire in a very unhealthy way.
Bertie:
No sister, no mouth stitches, no telepathic powers. He's still a clone. He is emotional blank most of the time. He no longer hates Mr. Blueberry, instead he see him as a father.
Ace Kumo:
He's Ken's uncle. He's very sweet and caring. I am still trying to figure out what I want his backstory to be.
Zeta:
Pretty much the same but maybe not as grumpy. He isn't asexual in this version. I decided to focus more on them being nonbinary. I have yet to state what their sexuality is.
