Rook Blonko (Dimension 3)

Rook Blonko is an intergalactic mercanary from the destroyed planet Revonnah. He became one after his planet was destroyed by the Overlord Ben Tennyson.

Biography:
Rook followed much of the same life as Rook from the prime dimension did. He was a Plumber and his first case was to help liberate Earth from Nega Ben's control. As it was theorized with the capital planet of the empire freed, then the rest of the planets in the galaxy would be freed as well. However unfortunately the attack to liberate Earth was not successful and so Nega Ben made Rook pay for his crimes by having Revonnah destroyed.

Rook was forced to watch his planet be destroyed and became so distraught after seeing it. In fact his personality changed as well and is a much more colder and hard person. When that did happen, Rook resigned from the Plumbers as they were unable to save his planet. Since then he now holds a complete hatred for Ben, but also the Plumbers since they failed in saving his world. It was at that moment he decided to become a mercanary and a freedom fighter for hire.

While he is not evil exactly, but also not entirely good, Rook will go to extreme measures to achieve his goals and gets his payment after finishing a mission. Sooner or later he feels that one day, he shall get the opportunity to destroy the Overlord and avenge himself, his planet, but more importantly the family he lost to Nega Ben.

Trivia:

 * His Proto-Tool had the Omnitrix symbol blotted out after his world was destroyed by Ben, who wore the Omnitrix.
 * He got his eye scar from his first and only failed mission as a mercanary.
 * His only loyalty is to himself and anyone who can pay the biggest amounts of cash.
 * Not only does he hate Ben, but also any members of Ben's family, especially Max Tennyson, as he was unable to stop Ben from becomming the most feared being in the universe.
