The main villains are the Frightful Four. The Frightful Four need a fourth.
Future member of The Defenders Captain Ultra tries out. So does a guy named The Osprey, who never goes anywhere.
As does future member of the Rangers and future Agent of SHIELD Texas Twister.
Weird he started as a bad guy. They eventually settle on Brute.
Impossible Man is hanging out with the FF, too, so lots of humor in these issues.
