FREEDOM FIGHTERS (vol. 1) #8 (June, 1977). Cover by Rich Buckler and Jack Abel.
The Freedom Fighters take on The Crusaders, who are just thinly-veiled versions of Marvel Comics' The Invaders:
Americommando = Captain America
Rusty = Bucky
Barracuda = Namor the Sub-Mariner
Fireball = Human Toch
and Sparky + Toro.
The names for the Crusaders were taken from Golden Age comic book characters, although Barracuda's character was actually named Barry Cuda.
This was actually part of an unofficial crossover with Marvel, wherein the two publishers' teams battled a group called the Crusaders. The members of the Crusaders, in both cases, were versions of the other publisher's group.
THE INVADERS (vol. 1) #14 (March, 1977). Cover by Jack Kirby.
Marvel's version of The Crusaders were analogues of the Freedom Fighters:
Sprit of '76 = Uncle Sam
Captain Wings = Black Condor
Tommy Lightning = The Ray
Ghost Girl = Phantom Lady
Thunderfist = Human Bomb
Dyna-Mite = Doll Man
