Sammy Paré was a 10-year-old Canadian boy whose genetic mutation caused him to physically resemble a fish. The physical nature of his mutation caused his classmates to ridicule him. Sammy considered using a gun he had obtained to shoot his tormentors, but before he could do so he was visited by Professor X and the Beast, who recruit him to enroll at the Xavier Institute for Higher Learning in New York. The Beast and Professor X do this with full knowledge of the weapon Sammy is carrying around; he is convinced to give it up. Sammy, with his parents' approval, chooses to enroll at the school for mutants in order to pursue an education free from persecution. On the return trip to the Institute, Professor X took a detour to Ireland to aid in an X-Men mission at Cassidy Keep. Sammy saved Juggernaut from certain death from drowning in the ocean, which began a friendship between the two. Cain subsequently reformed and became a surrogate father to Sammy, who also became friends with Carter Ghazikhanian and Icarus from the New Mutants. Sammy's mother eventually found out about his relationship with Cain and called upon the Canadian super-team Alpha Flight to bring the boy home. Sometime after Sammy's departure, Juggernaut suspected that Sammy's father Claude was physically abusing him. Cain, who had suffered similar abuse at the hands of his own father, decided to visit Sammy to investigate. When he and Northstar arrived at Sammy's home in Vancouver they found the boy covered in bruises. Cain snapped and beat Sammy's father Claude severely, destroying the Paré home in the process. He was subdued by the intervention of Alpha Flight. When Cain was subsequently incarcerated for violating his parole Sammy's mother testified on his behalf. After Juggernaut's release, Sammy returned to the Institute with his mother, who entertained the thought of a romantic relationship with Cain. Later, the Juggernaut infiltrated the Brotherhood of Mutants, working as a double agent for the X-Men. When Sammy stumbled upon the meeting of the group outside the school grounds, he assumed that Juggernaut had betrayed the X-Men and lashed out at him. Black Tom Cassidy used his control over plants to cause a group of vines to distort and crush Sammy's body mortally wounding him. With his last breath, Sammy told Cain that he hated him for what he'd done then died. Sammy's death caused Cain to snap again and attack the Brotherhood who were then subdued with the help of the other X-Men. Although the Brotherhood was defeated, guilt over Sammy's death troubles Cain to this day. When Tom's humanity was restored after M-Day, he showed remorse for killing the child stating "That wasn't me, Cain, you know that. I wasn't in my right mind... You've got to understand... that mad life, before... it was like some dream."
