Mister 7 was one of the rookie Secret Service agents assigned to the infamous Venture Compound Tag Sale. During the debriefing before the tag sale he was caught talking with Mister 12 and was almost forced to wear a dress by Mister 1. He is often seen with Mister 12 so they are mist likely partners. He was later darted and knocked unconscious by The Monarch while trying to apprehend him. He also at one point worked with Professor Impossible and helped him capture Ned, Hank and Dean.
