The villains established so far are Sadist and Surge, but those have officially been added to Iron Head's rogues gallery. Sadist is in custody, and as we've established recently in a one on one plot with Iron Head, Surge is still at large. Marcus is the only official villain that has been revealed right now, but introduced to the continuity of our living, breathing universe is another villain, Finn, who's a bad day away from being Night Watcher's arch nemesis. With that being said, Finn is now in custody, and a full write up and report will be posted here on him soon.
