Episode Title:
Riddle of the Sphinx.
Episode Description:
Rex, Six, and Bobo travel to Cairo, Egypt, where Dr. Holiday is investigating a recently uncovered ancient tomb which contains hieroglyphs seemingly depicting nanites. Black Knight also discovers the tomb, wherein they encounter a mummified pharaoh, Gharun Set, who comes to life. Gharun Set reveals that he is an EVO and was taught English by "the Great Father." Gharun Set escapes from his tomb and reactivates a series of technologically advanced pyramids buried underground, which rise up across Cairo. Gharun Set also destroys the Great Sphinx of Giza, revealed to be a tomb for an enormous two-headed cat EVO which he restores to life. Beneath where the Sphinx once stood, Holiday and Black Knight discover the fabled Hall of Records, which contains modern-day nanite technology. Rex confronts Gharun Set as he attempts to take over Cairo, but soon discovers that his technology is far too old to function. The Sphinx dies, and Gharun Set laments that he lives in a "world of lies" which EVOs have no place in, and that the Great Father told him of Rex. Gharun Set then dies. Later, Black Knight destroys the Hall of Records, and is revealed to have recovered a hieroglyphic picture of Van Kleiss.
