Origin
Santo Vaccaro

Santo Vaccarro is a young mutant who developed his powers pre- decimation. Much of his history is unknown but he came to the Xavier Institute and has had no known contact with his family since. He became close friends with Hellion when he was on the hellions and is now close to Anole.

Powers and Abilities

Santo's body is totally made-up with inorganic granite which grant him a number of superhuman attributes, just like superhuman strenght, stamina and durability. Rockslide possesses superhuman strength sufficient to lift about 75 tons without any effort. Although his "body" is composed of psionic energy and it cannot produce any fatigue toxins, Rockslide is still capable of tiring, however it is probably bounded to his mental state. Santo's body is considerably harder and more resistant to injury, however it is still possible to injure him by extreme strenght like Hulk, who had broken off Santo's arms and legs, and by high level energy protection like Nimrod, who had atomized his body.

After The Quest For Magik episode Henry McCoy stated that Rockslide is now a non-physical psychic entity who can form and control a stone golem, so he can survive without a physical body. It is unknown whether his ability to reform himself from rocks is a passive regenerative ability which occurs when Santo's body destroyed (or heavily injured) or a controlled process. Santo can consciously explode and can reform from any surrounding rocks.
