Sterling had a rather rough upbringing. He had been genetically engineered by Xeren as a replacement for Kaz Heater, whom Xeren found disappointing. After Kaz turned Xeren into The Demon, he kidnapped Sterling and trapped him in an orphanage. However, with Sterling's abilites, he knew he was not a normal orphan. He had a great memory and enhanced speed that could one day help him track down Kaz, so he could get revenge on him. Sterling spent his life for the next few years attempting survival, but was then captured by the Demon and forced to work just above Scarlet Outlaw. Although The Demon had originally been his father, he had been overtaken by evil and did not remember Sterling. Sterling managed to strike up a close friendship with Scarlet amidst working for The Demon.

- Enhanced Speed-His agility and fast running pace clearly exceed that of a normal human.
- He has never actually told Xeren that he is his creator.
