Krystalak

"Krystalak is a semi-sentient crystal organism, spawned by the same meteor shower that threatens to rip the earth apart. Born from the crystals, Krystalak seeks to bring all of their energies together to make himself into the ultimate monster. Like the crystals that spawned him, Krystalak is quite resistant to most forms of energy weapons, forcing opponents to fight him tooth and claw. Krystalak can expel crystal shards in a solid stream, bludgeoning foes from a distance. Krystalak can also overload his crystal heart - sacrificing his own physical integrity to damage everything nearby. With no ties to any existing alien or terrestrial powers, Krystalak seeks power at any cost."
