So.
He's just a guy.
He was literally a random kid on a planet of animal people named Spark when he happened to find an old artifact, and he met a kitsune that gave him fire powers.
He then used his powers to get a job working for the U.M.P., and he's paid pretty average wages despite the fact that he is one of their most powerful assets and has to deal with any threats that aren't big enough for heroes like Collector, Eggy, Inkmatas, etc. He also doesn't get recognized for it at all besides maybe the UMP giving him a raise of like 20 cents and a pizza party in his name if he were to defeat a threat to an entire populated planet (something that would be way out of his line of work).
He's actually very powerful, and could go head to head with some bigger heroes, at least before they go all-out, but because of that power gap, nobody cares about him. He isn't taken seriously, and isn't usually tasked with threats beyond anything city block level.
The most notable thing people (his coworkers) know him as is the guy who dated Inkmatas for a few months.
