Rockslide

Santo Vaccarro is a mutant whose body is composed of indestructible rocky material, granting him tremendous strength and durability. A natural athlete who excelled in wrestling and football, he enrolled at the Xavier Institute, where he became a student and eventual member of the New X-Men.

Rockslide burst onto the Marvel scene in 2004's New Mutants #9, the creation of Nunzio DeFilippis, Christina Weir, and Carlo Barberi, arriving during a fertile Modern Age renaissance for mutant storytelling. Over two decades and 90 catalogued appearances — with three collector-significant key issues to his name — he's carved out a genuine place in the X-Men corner of the Marvel Universe, showing up most prominently across Wolverine & the X-Men, New X-Men, and X-Men itself. Along the way he's shared pages with heavy-hitters like Wolverine, Cyclops, and Iceman, keeping some seriously legendary company. If you love stories about the next generation of mutants finding their footing alongside Marvel's finest, Rockslide is absolutely worth tracking down.
