Madame Hydra later assassinated the original Viper and took his alias. She then reunited the Serpent Squad, urging the Eel to avenge his brother's death. At this time, Princess Python joined the group. Cobra was not willing to serve Viper and challenged her to a battle, but he was easily defeated. Working with the warlord Krang in an attempt to raise the lost continent Lemuria, the Serpent Squad were ambushed by Captain America, then in his Nomad identity, who defeated the Eel and Princess Python. After Cobra eventually turned on Viper, she shot him in the back and managed to escape, while Nomad rushed Cobra to the hospital.
