The Jinx of the Sphinx
In alliance with the Nomads, Dr. Who placed an electric brain within the Sphinx and programmed it for 3 full days of destruction. Dr. Who ordered the Robot Sphinx to destroy the Suez Canal with intentions to destroy the other great wonders of the world. Swimming down the river, the Robot Sphinx began to destroy boats and anything else that blocked its path. The Sphinx soon interrupted a tour ship that was carrying Susan Bond and Captain Englehorn as passengers. Dr. Who revealed himself to the Bond family and told them of his plans. In response, Bobby Bond called for King Kong who emerged from behind a hill. Dr. Who made a quick escape and left the Robot Sphinx to continue destroying the canal. Kong approached the Robot Sphinx just as it was about to destroy the tour ship. He attempted to attack the Sphinx with a palm tree but the Sphinx melted it out of his hands. As the Sphinx needed to recharge its lasers after using them, Kong retaliated by forcing the Sphinx under the water. The Sphinx short-circuited and was then thrown across the river by Kong, sinking to the bottom.
