Atomix

From Ben 10 Planet, the wiki resource for Ben 10!

Atomix is an alien obtained by a future Ben Tennyson in an alternate timeline, he is first mentioned in the episode "Ken 10".

There is not much known about him, but we do know that Atomix is one of the 10,000 aliens on the Omnitrix of Ben 10,000. Atomix was mentioned by Ken Tennyson while he looked through his Omnitrix (Ken didn't get it, much to his disappointment).

Many fans think that Atomix is atomic powered or radioactive alien with nuclear powers.
