Character description from "tech spec": 
A master of the body-structure science, Skyquake pioneered the development of the first mass-produced "Skyraider" body frame that he continually strives for its perfection.  The development of unique "talent powers" and ever-larger and more combat-capable designs are his engineering specialties.  As a reward for these feats, he was given his own squad to command, though he is far from thrilled with those whom he leads.  This is no surprise, as he is filled with hatred for anything that falls short of his merciless ideals.  Prepared for all contingencies, he is rumored to have a secret stash of body designs and backed-up programming culled from his various minions.  He focuses his hate through single-minded rationality that drives his monstrous scientific and combative endeavors.  His vast array of sensors allows him to absorb and interpret immense amounts of visual information.  To outside observers, this awareness appears almost supernatural.  His sensor-laced right arm is ultra sensitive and vulnerable to attack.
