The Sphinx is, in reality, the monument in Egypt. Unlike the real-word version, this Sphinx is frowning and has colors, a large collapsed section in its chest, and its forearms are ripped off, although still intact. The Sphinx's head and forearms float by themselves, most likely due to the crystal energy.
The Sphinx has the ability to unleash a large purple laser from his forehead. It can also shoot finger missiles (similar to the Showa MechaGodzilla), and he throws boulders and does a slam attack.
