Yes, that's it! Two teams called The Crusaders. I believe there was a Comic Book Legends Revealed about this awhile. The two writers, Roy Thomas and Bob Rozakis I believe, set this up on purpose. Fun times in the 70's! :)
Part Kryptonian, Part Asgardian, all Genius.
If we could only get real Invaders and Freedom Fighters team-up story set during WWII.
(I know, sometime after hell freezes over . . . )
Everything I state is JUST MY OPINION. Take what you like and leave the rest.
