After several defeats at the hands of the Hulk and his allies, each of the U-Foes are banished to a different dimension. They manage to reunite and find their way back to Earth when the mutant Portal's powers began manifesting. The U-Foes attempt to murder Portal to keep him from opening another portal to banish them, but are defeated by the Avengers. They later attempt to kidnap Portal to exploit his mutant powers, and are defeated once again by Captain America, Darkhawk, and Daredevil.
