Unlike Triss, in my mind gimmick/ability/theme mean nothing for the name.
Eh, screw it, I'll just use myself as my nickname.
People actually call me Crank in real life. My brother calls me Crank, it's my legitimate nickname.

Does this mean I'm cranky, weak, a meth-head or intense?
No.
Crank was part of a childhood rhymey name my parents called me. Daniel Spaniel Spanky Crank. I don't know how they came up with it, but Crank stuck.
If you want a good name, look at the history of your character to find it.
Alright, now I'll walk you through Hollywood. He fights with blowguns. Can you tell this by the name? No. Do I care? Significantly less.
Before he joined wRHG he planned on being an actor and acquired the nickname Hollywood in drama club. Upon joining it, he stuck to what was familiar to him, rather than just becoming Dart or something. It just seemed to make sense.
Third option of course, is just pick an actual name and make it stand out. Anyone who's been around since FA knows Kyra, and I don't just mean the username.
You don't need a reworded name to have a good one, and in fact, it comes off a bit bland in my mind. Blaze the Pyro is somewhat implied. Why bother? Consume is a bit different. Who is this, a cannibal? Oh! He's some psycho who likes to watch flames eat what others hold dear! That makes him a moderately terrible person.
A name is going to be the first impression here, and it's just going to be dull if you make it the power. You can make it reveal the personality, who the person once was, showcase a human element, or just identity.
EDIT: Wow. First I lose the ability to write short stories and now I can't even make short posts? I'm not sure how I feel about this...
