Colonel James Harper



James Harper is a corrupt colonel that works for a sinister science division called project Cadmus who was also best friends with Hank Henshaw. After Jon Jonez revealed himself the DEO just to keep Kara from being arrested for not being able to fight off the red kryptonite's effects, Harper brought his military unit along with Lucy Lane to the DEO to find out who was in on the Martian Manhunter's infiltration as Hank Henshaw and when he cared less on how messed up the real Henshaw was, he and his unit took Jonzz and Alex Danvers hostage leaving Kara to convince Lucy to renounce her partnership with Harper as they both stopped them from taking Jonzz and Alex to Cadmus and just when Jon was about to erase his memory on everything that was going on, he stopped because he saw that Alex's father was still alive which leads him into just subduing Harper as the two fugitives took off leaving Kara and Lucy in charge of running the DEO.
