Captain America #342
"The Snake Pit" Story by Mark Gruenwald. Art by Kieron Dwyer and Al Milgrom. Cover by Ron Frenz and Al Milgrom. Diamondback and Sidewinder barely escape from the Serpent Society's headquarters after avoiding capture by the Viper's serpent squad. Next Diamondback meets up with the Captain (aka Steve Rogers) at a local gas station to explain the dire situation back at the Serpent Citadel. The ensuing battle is an awesome free-for-all as the Captain, Diamondback, D-Man, Falcon, and Nomad fight all the serpents including Anaconda, Black Racer, Coachwhip, Cottonmouth, Puff Adder, Rattler, Rock Python, Slither, and the Viper! Cameo appearance by the Black Panther.
