When Tucker was under the influence of the Pharaoh Duulaman's scepter, he turns the entire school into his Ancient Egypt, where all the students and Lancer must serve as his servants, vowing as he does so to finally make everyone listen.
With Tucker in charge he commands them to build a Sphinx as a monument to his highness, but later when Danny returns, Hotep RA grabs the scepter and begins to do things his own way; namely, bringing the sphinx statue to life to take care of Danny. He tries to fight the beast but in vain; not even his Ghostly Wail can destroy it. Hotep-Ra then brings to life hieroglyphics - a bird, a jackal, and a giant scorpion - to help the sphinx with its job. While Danny continues to do battle, Hotep-Ra gets sick of waiting and personally goes after Tucker himself. When he realizes that he can't with the sphinx, Danny convinces Tucker to try and get the sphinx to listen to him, since the sphinx must obey the pharaoh and technically Tucker still held the title. After Tucker extracted an apology from Danny, he commands the sphinx to stop, and then to go after Hotep-Ra.
- Superhuman strength and endurance: Due to his size and the fact that is made of stone, the Sphinx is incredibly strong, even strong enough to defeat Danny and sent him flying. The Sphinx is also able to take on Danny's ghost rays with no ill effects and is the first and only character capable to resist Danny's Ghostly Wail with no damage at all and holding against it.
- Fangs: Since it is half-lion, the sphinx has big fangs.
- The sphinx is similar to the Giant Sphinx from another Butch Hartman show, The Fairly OddParents. In both shows, the sphinx was brought to life by the protagonist's enemy (for Danny, it is Hotep RA; for Timmy, it's Mr. Crocker). In both instances, the sphinx is brought to life in order to destroy the protagonist, but they manage to turn the sphinx against the villain.
