What powers does Havok have from X-Men have?
Havok’s body is constantly in the process of absorbing cosmic radiation. When each of his body’s power-storage cell enclaves reaches its capacity, excess cosmic energy is thereafter absorbed and immediately re-emitted in negligible quantities. Upon the total expenditure of all his available energy, it takes Havok’s body about 16 hours to recharge to its peak level. The act of concentration involved in releasing his energy in anything other than an omnidirectional wave is physically exhausting for Havok if he continues it over an extended period of time.
