The Mad Titan Thanos, a melancholy, brooding individual, consumed with the concept of death, sought out personal power and increased strength, endowing himself with cybernetic implants until he became more powerful than any of his brethren. Thanos possesses the superhuman physiology of all Eternals, granting him superhuman strength, endurance, reflexes, and agility. His skin in nearly invulnerable, particulary against heat, cold, electricity, radiation, toxins, aging, and disease, and he can survive indefinitely without food or water even before his "curse" from Death left him immortal, unable to die. His mind is also invulnerable to most forms of psychic attack, and can project a psionic blast of energy as well as blasts of plaa/coic energy from his eyes and hands.
