Little is known the life of M'Gula before he joined a group of snake-themed villains led by the terrorist Viper when she aimed to win control of the mercenary group the Serpent Society.
It is known, however that M'Gula is citizen of Rudyarda, probably a mutant, and that he worked as a mercenary and criminal throughout all of Africa. At some point, M'Gula obtained from AIM the weapons that he carries (it is unknown if AIM also gave him his powers, therefore meaning he would not be classed as a mutant). M'Gula took the name Rock Python, and joined Viper's group. When the Serpent Society was attacked by Viper, they tried to wrest control from its leader Sidewinder. Rock Python and the rest of Viper's group vanquished the Society and took control.
However, one of the Society, Diamondback escaped with an unconscious Sidewinder and alerted Captain America, then known as The Captain, and his allies. The heroes stormed the Serpent Citadel, and during the battle Rock Python fought Nomad and the Falcon. Rock Python took part in Viper's plan to poison water supplies with a toxin that turned ordinary humans into snake people.
Rock Python remained with the Society when its leadership was taken over by King Cobra and, among other missions, was involved in apprehending Diamondback and putting her on trial for her supposed betrayal of the Society's secrets.
