Sphinx
Strength Level: The Sphinx possessed superhuman strength and could lift (press) about 85 tons. (Note: When the Sphinx possessed the power of the central computer of Xandar, he could increase his strength far over the Class 100 level, enabling him to lift far over 100 tons.)
Known Superhuman Powers: The Sphinx possessed the power of the Ka stone, an ancient jewel of unknown origin, apparently sentient, which enabled its wearer to manipulate vast amounts of mystical energy in various forms. He could project the mystical energy as beams of concussive force, light, or heat. He could channel the stone's energies into his own body, augmenting his physical strength. The Ka stone also enabled the Sphinx to "read" minds and to retain all the information he thereby acquired. Using the Ka stone he could drain vast quantities of energy from other sources into himself, further augmenting his superhuman powers. The Sphinx could also use the Ka stone to enable himself to fly unaided through an atmosphere or through the vacuum of space unharmed. The stone gave him extraordinarily high resistance to physical injury and enabled him to exist indefinitely without oxygen.
