Ben Tennyson/Earth-69

Ben Tennyson is the teenager, superhero main character of Ben 10: Alien Universe. Armed with an alien device called the Omnitrix, he can transform into one of over one million aliens to step a mile in their shoes. His cockiness and overall attitude and personality are very similar to that of regular Ben. He even shows a lot of love and devotion to making sure his cousin Gwen is okay over all, rather having Gwen alive than Kevin Levin, an old villain turned into a new ally.

Trivia

 * Alien Universe Ben is confirmed to never unlock Armodrillo, but he will at one point defeat Ultimate Aggregor nonetheless, and this Ultimate Aggregor will still have the DNA sample of a Talpaedan (Armodrillo's species).
