Peter Quill is son of a human and a Spartoi, and his hybrid physiology grants him peak human abilities.
Peak Human Strength
Peter Quill was born with physical strength equal to the peak of human potential. Peter's physical strength is above that of a normal human being.
Peak Human Durability Peter's body is more resistant to physical injury, to variable degrees, than that of an ordinary human. He seems capable of taking several gunshot & puncture wounds as well as beatings and still stand on his feet.
Peak Human Agility
Peter's agility, balance, and bodily coordination are at levels that are beyond the natural physical limits of even the finest human athlete.
Peak Human Stamina: Peter's body eliminates the excessive build-up of fatigue-producing poisons in his muscles and his musculature generates considerably less fatigue toxins than the muscles of an ordinary human being, granting him superhuman levels of stamina in all physical activities.
Peak Human Mental Process
Peter was born with enhanced mental performance, allowing his mind to process information quickly, giving him an accelerated learning aptitude. He has mastered various alien languages and customs with ease.
Spartoi have a life span that is three times longer than a human from earth. When his father was 100 years old he appeared as if he were in his mid-30's. Due to his hybrid nature it is unsure how he will age, but it will likely be at a decelerated rate.
