The Star Chariot was a ancient spaceship said to burried beneath the desert according to a Native American legend.
Miles Mayhem, leader of V.E.N.O.M. posessed an ancient Indian tapestry that prophesied in symbols that the Emerald Arrow-Head would point the way to the Star Chariot, an alien spacecraft burried beneath the desert a thousand years ago. Mayhem intended to adapt the spaceship's propulsion system for an unbeatable new generation of V.E.N.O.M. vehicles.
One half of the arrow was lost over a thousand years ago, but Mayhem somehow managed to come into posession of it after ten years of searching. Now all he had to do was get the half owned by the Slow Eagle family. After first cornering Chief Slow Eagle in the desert, Mayhem and his agents learned the Arrow-Head was now the property of the Chief's grandson Daniel. Shortly afterwards they kidnapped Scott Trakker who was not only wearing the arrow-head around his neck at the time but also dressed in native American clothing.
After combining the two pieces of the arrow-head, they fit onto a circular tablet forming a compas. It pointed towards Mesa Verde National Park where, it uncovered a secret entrance between ancient ruined. Inside was the Star Chariot. However, the long hallway was equiped with several boobytraps including automatic doors and giant rolling pins.
Although the V.E.N.O.M. agents managed to get inside the spaceship, they were chased off by Rhino's Ultra Bright lights. Scott and T-Bob were apparently crushed by one of the rolling pins, but later reappeared inside the Chariot. Both claimed to have dreamt that they were taken to an alien planet by a UFO to be fixed up. As soon as the Star Chariot was empty, it took off for an unknown destination. Matt Trakker concluded that it had gone to a safer place, waiting to reveal it's secret only when all of the Miles Mayhems of the world are gone.
