Adam Warlock possesses a number of superhuman properties and powers derived from his artificially determined genetic structure. His bone and muscle tissue is denser than human, endowing him with superhuman strength and resilience. Among his body's special adaptations are an enclave of cells able to tap and transform cosmic energy for personal use. Warlock could use this energy to enhance his physical strength, endurance, and powers of recuperation. He could also employ cosmic energy to negate the force of gravity beneath him, enabling him to fly. In an Earthlike atmosphere, Warlock was able to attain the speed of sound (770 miles per hour). He could use his cosmic energy to locate and enter natural space-warps (discontinuities in the fabric of space) in order to traverse interstellar space. He can also project cosmic energy from his hands as concussive force.
Warlock's energy-manipulating powers waned at the time he was given the soul-gem by the High Evolutionary. No longer could he direct concussive force from his hands or enhance his strength. Whether this power limitation was caused by his symbiotic relationship with the soul-gem or some other factor is not yet known. When Warlock was summoned from the soul-gem to defeat Thanos, he seemed to possess these cosmic powers once more.
He is is able to spin a cocoon around him at will in a matter of seconds. He did so infrequently during his short life, usually to protect himself from mortal harm, and usually he would emerge from the cocoon at a further level of physical or mental maturity. It is not known where the substance of the cocoon came from, or where it went after he emerged from it.
