Well I'll help, Just a heads up, your pic of Griffin doesn't work.

Name: Griffin
Age: 25
Appearance: 
Ability: manipulate light
Crime: murder
Personality: Griffin is very gruff and aggressive. 
Bio: Griffin doesn't talk a lot about his past. He feels he was justified for killing the people he killed.

So everything up to Personality and Bio is fine, like mine, With Personality, I find it hard too, so I describe the character then add some mannerisms, like eg "Griffin, when extremely angry, will take his anger out on objects or others uncontrollably" Or "Griffin is very aggressive and acts all tough but deep down he uses it as a coping mechanism, with the traumatic events from his past changing him" Something like that, go into a little depth about your characters personality, mannerisms and mentality. And then with bio, some characters will not talk about their past IC, but when making the characters, it usually best to write one, Bios can be really hard, I understand, but maybe just choose the event from Griffins past that caused him to have powers, of if he was born with it, explain how he got into prison or the events that surrounded it. A small bio is perfectly fine, but you still will want to add a Bio. It will give an idea to others how your character will act and why they act that way. Just advice, your choice to take it :D
