Tempest possesses superhuman strength, allowing him to lift in excess of several tons on dry land. He can survive at depths of up to 3,400 feet below surface level. His body contains fluids that adjust to give him buoyancy at varying depths. His body also produces gases that push out against the ocean pressures as heavily as they push in, preventing him from being crushed at great depths. His body is also highly impervious to physical injury. His bloodstream is filled with an amino acid that keeps his body from freezing in the ocean depths, although his own temperature is naturally quite high, allowing his muscles the heat they need to swim at such high speeds.
