Not much is known about the mysterious mutant called Sunder, except he was a founding member of the Morlocks, abandoning whatever identity he may once have had in the surface human world. Sunder was the aide to Callisto, and was the muscles of his group and was very protective of them, especially Callisto. On Callisto's orders, he kidnapped Angel to the realm of the Morlocks. He later aided Callisto in abducting Kitty Pryde and attempting to force Pryde to marry the Morlock Caliban. He also served the wizard Kulan Gath when the latter took over Manhattan. Some time later, he took up residence on Muir Island. He briefly joined the "Muir Island" X-Men organized by Moira MacTaggert, but was shortly killed by the cyborg Pretty-Boy with a bullet wound in the back when the Reavers invaded Muir Island.
Powers and Abilities
Sunder's mutation granted him various superhuman physical attributes.
Superhuman Strength: Sunder possessed great superhuman strength. At his peak, he was capable of lifting about 70 tons.
Superhuman Stamina: Sunder's superhumanly enhanced musculature was much more efficient than that of a normal human. His muscles produced considerably less fatigue toxins during physical activity. At his peak, he could exert himself for up to 24 hours before the build up of fatigue toxins in his blood began to impair him.
Superhuman Durability: Sunder was tougher and much more resistant to physical injury than a normal human. He could withstand great impact forces, falls from great heights, exposure to high temperatures, and small caliber bullets without sustaining injury.
Although he had little formal training, Sunder was a formidable hand to hand combatant. He primarily used street fighting techniques that allowed him to make full use of his strength.
