Rockslide(Santo Vaccarro, from X-Men)

Rockslide is a mutant whose body is composed of inorganic granite. He boasts superhuman strength, stamina, and durability. At first Rockslide made rock projectiles from his limbs, but now he can explode his body and reform from surrounding rocks. When Rockslide explodes and reforms he is slightly different in appearance and sometimes abilities. The last time he reformed he was an elemental lava creature. Due to the changes he experiences when reforming, Beast hypothesizes that he is actually a psychic entity rather than a physical one, and he has the power to form and control a stone golem.
