He even killed two of his "Betas," Tracy Stewart and Josh Diaz, in order to steal their powers of Kanima venom production and electromagnetokinesis, respectively. To do this, he pursued several different leads that he thought could help him achieve his goal, including obtaining Belasko's talons, capturing Deucalion (the only surviving expert in stealing powers from other creatures), and attempting to capture Lydia Martin, knowing that her Banshee connection with Jordan Parrish, the Hellhound prophesied to battle the Beast, would lure both Parrish and the Beast to him. Throughout Season 5B, Theo continued his quest for more power with the help of his packmates, only this time, he focused his sights on stealing the powers and lycanthropy of the Beast of Gevaudan, who had recently been resurrected by the Dread Doctors. As a consolation prize, Theo used the Dread Doctors' green serum in order to resurrect four of the previously killed "failed" Chimeras whose bodies were left at the Nemeton, creating his own Chimera Pack in which he was the self-appointed "Alpha" (despite the fact that he was neither a real Alpha nor a real Werewolf). Unfortunately, Theo's plan, while perfectly executed for the majority of the half-season, was foiled when Mason Hewitt arrived and stopped Liam Dunbar from killing Scott at the last moment (since Theo, knowing only a Beta of a True Alpha's own making could steal their power, needed Liam to become an Alpha first in order to steal the power for himself). He posed as a recently-bitten Werewolf whose Alpha died before his first full moon, leaving him as an Omega in reality, Theo was trying to get close to the members of the pack, as he planned turning them against their Alpha Scott McCall and eventually killing him in order to steal his powers and become Alpha himself, coveting the unique combination of supernatural creatures that made up the pack. Theo returned to Beacon Hills for his senior year in the autumn of 2012 and wasted no time seeking out the McCall Pack in hopes of joining them. He went to school with Scott McCall and Stiles Stilinski up until the fourth grade, which was when his family left Beacon Hills, a year or two after the death of Theo's sister, Tara. He was the first Chimera created by the Dread Doctors who managed to successfully complete his transformation without rejection, though he was not considered a true success.
