Rockslide (character)

Rockslide (Santo Vaccarro) is a fictional mutant superhero appearing in American comic books published by Marvel Comics. The character has been depicted as a member of the X-Men, a student in the Xavier Institute, and a member of the former Hellions squad therein. After M-Day, he was one of only 28 students to retain his powers. He is best friends with Julian Keller (Hellion) and is extremely close to and protective of Cessily Kincaid (Mercury). Despite his earlier appearances as a stereotypical school bully, he has evolved into a good-natured (though extremely boastful) and fiercely protective friend to most of the school's students.
