Dillon9988 is right.

And to the question "why use ultimates?", my answer would be:

-Because the B10 franchise needed a new idea to keep running, and all what the producers got was the "ultimate" thing idea.

-Because the ultimates, as migosabi made clear, are not the same as his infinites. The ultimates are better, in the way that they're more powerful, but still not perfect. Enhanced version, but not SO enhanced that the use of one of them would be enough to knock out all universe's villains.
