Atomix

Atomix is the Omnitrix's DNA sample of an unknown species from an unknown planet.

Appearance
Atomix has a humanoid robotic appearance that's quite taller than Negative Ultimate Humungousaur. He has a green and white body. He has large cylinders on his arms, near his wrists, that are full of a green energy with dark green bubble-like spheres, and these spheres constantly move on Atomix. He has the same energy on his Omnitrix-shaped chest. His mouth doesn't move when he talks and his head is a pointed, armored helmet.

Atomix wears the Omnitrix symbol on his green and white belt.

Personality
Atomix acts with a kind of "righteous" personality, and speaks to others with proper titles, such as referring to Max as "grandfather," and Gwen as "cousin."

Atomix names his special attacks, much like a character from an anime show.

Powers and Abilities
Atomix can create atomic blasts, which can do a massive amount of damage to its surroundings, from his hands. The way he creates the blasts is by chanting "HAA-MEE-NA HAA-MEE-NA HAA-MEE-NA-HA!" Atomix doesn't need to chant every time he does an attack but does so for some attacks so he can focus his power.

Atomix is able to activate his cylinders on his arms and his Omnitrix-shaped chest to melt nearby objects.

Atomix is strong enough to take out Negative Ultimate Humungousaur with a single punch, or kick an object up to a very high altitude. His hard body gives him substantial protection against physical attacks.

Atomix is capable of flight.

Atomix's main attacks are 'Fissile Whistle' (a flying ramming attack) and 'Nuclear Winner' (a massive blast of energy that can easily knock out Negative Ultimate Spidermonkey and other enemies, as well as devastate the surrounding area). Atomix can create light fusion, also known as 'Fusion Cuisine' which can burn up Zs'Skayr and slightly harm Lord Transyl.

 * Atomix was first seen in the season four's sneak peek of Omniverse.
 * The way Atomix charges his attacks is based on Goku's Kamehameha chant from the series Dragon Ball, but sounds like the "Homina Homina Homina" exclamation of Ralph Kramden from "The Honeymooners".
