Ben Tennyson (Dimension 44)

In this reality Ben did not find the Omnitrix, but his cousin Gwen did. So out of spite and jealousy towards Gwen, he became a mercenary.

Biography:
On their summer trip during an outing in the forest Gwen found the Omnitrix instead of Ben. Gwen unlocked these amazing alien powers from the device and she instantly wanted to become a superhero. Ben on the other hand was jealous and upset that she found it and not him. Gwen got to play superhero and the public loved her. Gwen was a very competent and very coordinated as a superhero. Ben at times would try to help out on Gwen's adventures, but she out shined him every move and he was treated as a second banana by the public. Ben could not escape Gwen's shadow, but it got a lot worse when the two of them got older. Gwen was offered by Max as a chance to join the Plumbers which she was excited about. Ben on the other hand wanted to join as well because he finally felt this could be a good way to finally out class Gwen.

So then they both enrolled in the academy and over the past few months, both Gwen and Ben excelled at everything. Gwen on the other hand did better because she was better at the academic portions of the training. However Ben excelled at fighting, marksmanship, piloting space crafts, and many other skills. However it was just as bad as ever because even after they graduated and went on missions, he could not out shine her. The Omnitrix made Gwen special and he was just a normal fifteen year old kid. So out of anger he quit the Plumbers and went to the stars to find his own calling. Eventually he did on a planet when someone put a bounty on an escape prisoner who had evaded authorities. Ben found his new calling as a mercenary and assassin for hire and he loves every minute of it. He makes lots of money and gets to put his skills he learned to the test when it comes to hunting down aliens and killing any idealistic politicians.

It's the perfect job for him, but there have been times where hits have been put out on his own cousin. Ever since Ben's new life was discovered by a off world Plumber base, Ben has become a disgrace to his family especially to his grandpa. Many of them have tried to get him to see the error of his ways, but Ben refuses to change. His life now has meaning and he may finally out shine his cousin Gwen by eliminating her and taking the Omnitrix for himself.
