As you might’ve guessed, this here is Hydrogen, the main protagonist of the Atomic Series game. He lived most of his life in the alleyways of Minimus City's main district, but his life changed when he was able to become a member of Planet Minimus's elite task force, the Minimus Protection Agency. As an agent, 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 doesn't know how to have fun, though! If he has free time, he loves to spend it with friends, especially with Helium.
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…
