It's the element Hydrogen personified for the (codenamed) Atomic Series, a game idea that I'm working on that involves each and every one of them. I hope to come up with a design for all 118!

Hydrogen, or Hydro for short, is the main protagonist of the Atomic Series. As a member of the Minimus Protection Agency, he takes his job seriously and with pride. He’s also very literal and takes things more seriously than he should, which makes him all the more oblivious to most forms of humor. Doesn’t mean he can’t be the butt of the joke, though!
Hydrogen specializes in hand-to-hand combat, and is the fastest out of the four playable characters. With his speed, he can dodge enemy attacks easily and can attack them from behind. Thanks to an accident at the Minimus Power Plant, he was imbued with the power of a negatively charged ion, which allows him to take in attributes from different enemies to boost his stats. If he takes in too much, however, he’ll change into…something else…

Hydrogen belongs to me!
