We all spend so long attempting to accurately describe our characters, spending hours describing their backstory and their personality. It's nice to generalize sometimes, or even be lazy - so what's the worst possible way you can summarize your characters?
Prism, for example, is a PTSD-stricken chicken with a hairtrigger hurricane problem. Jima's the Grimm fetishist with a thing for expensive ink drawings, and my beloved twins as overtly sexual egotistical maniac with daddy issues, and his the sexually-repressed bookish nerd of a sister, also featuring daddy issues.
Regardless, do your best - or your worst - to describe your characters.
