He first met the Wildcats when he was hunting a SPB that was trying to kill Spartan. Spartan had Grifter kill the SPB and then he offered Agent Wax a job. Wax kept an eye on the National Park Service and made sure they didn’t investigate Spartan too much. He also worked with Spartan a lot, which kept him out of the office and prevented him from doing his job so he got demoted. As payback, he used his hypnotic powers to sleep with his boss’s wife (not just once but on a regular basis). Eventually his boss found out and tried to kill him. Wax made him kill himself instead and then used his hypnosis to make everyone in the National Park Service think he was the boss. This allowed him to run the National Park Service and still work with Spartan (and also keep sleeping with boss’s wife).
