Jacob Nion

Jacob Nion was an human male who joined the Dark Titans and trained to be an assassin. During the Great Hero Purge, Jacob and the other titans ran into Team Dark, and they decided to help them exterminate any surviving hero and heroine. He would prepare to kill any other heroes, except for Sophitia Alexandra, whom he fell in love with.

Joining the Dark Titans
When Jacob was a child, his parents were killed during an unknown battle. Jacob survived however, and was found by the Dark Titans, and was taken to their hideout. He spent many years training to become a powerful assassin. A couple of the Dark Titans disliked Jacob due to his personality. However, Jacob did manage to kill a few heroes.

Meeting Team Dark
Sometime after Order 66, he and his titan teammates ran into Darth Speedy and his companions, who are searching to destroy the surviving heroes. The Dark Titans decided to join Speedy's team and to help them out. The titans even trained harder to become more powerful and skilled. Sometime later, Jacob met and fell in love with Sophitia. Jacob might even have an ultimate confrontation with Darth Speedy and the Dark Titans.
