I see, then I think I might like to include a short biography in my CS as well, since the characters are "people" in a sense. What do we call them anyway?

Also, for "age". I don't know how far we are in the future, but I imagine that most of the characters wouldn't have been around for more than a few decades (depending on when this whole gladiator thing began) since they were created in a lab and all. I'm guessing they would have been created mature, instead of being raised like a child (or pet?) because that may humanize them too much.
