He primarily appears in Ben 10: Milky Way Race.
Atomix's abilities include:
- Nuclear Manipulation
- Atomix is essentially a living nuclear reactor, generating nuclear energy that he can utilize for various purposes.
- Enhanced Physical Attributes
Atomix is a large white robotic humanoid alien with green and black markings. Viewports into his body are visible on his arms, chest, and head, displaying a green, flowing energy. The Omnitrix symbol is on his belt.
His new armor provided by the Legacy Omnitrix is about the same height as his original armor, but is notably less bulky and has gray markings replacing his green.
Atomix is endlessly overconfident, and his abilities could cause a total nuclear meltdown if he were ever to lose control.
- Re:Start - Used to battle Kraab. His armor ends up breaking due to Ben's recklessness, leading to a nuclear meltdown that killed Kraab, destroyed a good chunk of the surrounding city, and critically injured Rook.
- This version of Atomix was influenced by the appearance of Kamen Rider Fourze.
- Atomix is evidently Ben's most powerful alien aside from Alien X.
- Atomix's attacks are focused via repeated chanting. It is debatable whether this has an actual physical effect or is simply Atomix focusing his mind.
- In Milky Way Race, Atomix has switched from chanting "HAA-MEE-NA HAA-MEE-NA HAA-MEE-NA-HA!" to "HORA HORA HORA" because if he has to chant a bad pop culture reference it might as well be from something I like.
