FX7 is an extremely powerful mutagen, created by Carrick Masterson by extensively by modifying the psychedelic Tryptamine 5-MEO-DIPT in San Francisco in the mid- to late Sixties. He created it as a way to form his own superhuman group, originally called the Levellers, but later the Front Line.

However, the effects of FX7 vary wildly from person to person – Masterson refers to the process as ‘tuning’, and even the doses and methods of administration vary based on each subject’s medical work up. Although only one dose is required, to actually make it kick in takes a high level of adrenalin response: a shock or fright. When that happens, the subject can expect 12 hours of horribly mutating pain, after which they will wake up with superpowers.
