Scooby-Doo! Where On Mars Are You?
Angrily watching as Mystery Inc. was briefed on recent alien sightings and the disappearance of Russian cosmonauts by his boss, Fred's uncle Max, Col. Jenkins wouldn't appear again until he was unmasked as one of the aliens and revealed that he'd been planning to start his own society on Mars. It's likely that he was the alien responsible for tying up the American astronauts as the two men he was revealed to be working with were described as his henchmen.
