Biography
While performing military services in a war-ravaged country, Viper came upon an infant whom he believed saved his life by drawing his attention away from an area which was suddenly detonated. In the English dub, it is simply stated that the rest of the unit he was with was ambushed and captured while he left them. He adopted the child, Pierce, and came to regard him as the "angel" in his otherwise torturous life. Years later, chasing after Duel Monsters cards given to him by Viper as a present that were swept up in the wind, Pierce was run over by an oncoming vehicle (the dubbed version of that scene is cut, here, he died of an illness).
Later on, Viper entered Duel Academy in the third year and in a desperate attempt to aid Yubel (who promised to raise his son from the dead), Professor Viper pitted students against one another in Survival Duels. The only concern he had was that Adrian Gecko grew suspicious of him. Viper attempted to get rid of him by forcing him into Survival Duels and setting the Bio-Band drainage level to maximum in an attempt to kill him, knowing that Adrian would still Duel. However, Adrian forced Viper to lower the level when he got the entire Ra and Obelisk dorms to Duel at the same time. When Jaden Yuki and his friends broke into Viper's hideout, Viper found that Yubel still needed more energy and faced off against Jaden in a Duel (in the English version, part of the reason was that Yubel wanted to see Jaden suffer). When he lost, Yubel, manifesting in energy form as Cobra's son, modified Cobra's memories of Rick's death, deceiving him into believing that Rick never died. In a stupor, Cobra followed his "son" to the edge of the platform, where he seemingly fell to his death. (In the US version: after Yubel grabs Viper's face, he simply disappeared, which heavily implies his death, though this is not specifically stated.)
After Jaden became The Supreme King, his words alongside Professor Stein's linger in his mind, specifically about his not treating Duels as anything more than a game. Viper is seen one more time prior to Jaden's final Duel with Yubel as Jaden remembers all the people Yubel has wronged.
