Theo O'Connor

Theodore "Theo" O'Connor (born May 9, 1990) was a police detective of the South City Police Department. He was the partner of Jet Willis, the boyfriend of Amanda O'Neil, and a good friend of Ben Carone but rival to Adam Hart. He was one of the first police officers in the SCPD to learn of the existence of superhumans - second only to Jet - and eventually learned of Ben Carone's identity as Zero. Learning he was doomed to die at the hands of Xeno, Theo would sacrifice himself in an attempt to shut off Xeno's doomsday device, saving the city.
