Biography
The Freefall Warriors encountered the Fourth Doctor at the Festival of Five Planets, whereupon Machine Head took the Doctor and Dr. Ivan Asimoff on a ride in his spacecraft. However, during the flight they ran into a party of raiders from the sixth planet and were shot down over an asteroid. While the Doctor repaired the damage, Machine Head contacted the other Warriors and warned them of the raiders. They set off to battle the raiders and destroyed them before they could cause major damage to the Festival. They were hailed as heroes on their return. (COMIC: The Free-Fall Warriors)
