This papercraftis designed by gustavo santome. Stratos is one of the Heroic Warriors. He has the power of flight and energy projection, and is the leader of a race of birdpeople who inhabit the airborne city of Avion, high in the Mystic Mountains. He appeared regularly in early episodes of the 1980s cartoon series by Filmation, and the season 2 episode "Betrayal of Stratos" explained that Stratos and his people gained their power of flight from the Egg of Avion, a sacred relic of his kingdom.
The 2002 cartoon series by Mike Young Productions portrayed Stratos as a long-serving member of the Masters and seemingly one of the older members of their ranks. Stratos and his race featured prominently in the episode "Sky War" which revealed that Avion has had clashes with the people of Andreenos but, thanks to Stratos and the Andreenid captain Buzz-off working together as Masters of the Universe, there is now peace between the two peoples.
No origin was ever given for Stratos in either of the two cartoons, but a comic produced by MV Creatons to accompany the 2002 series revealed that his entire race was flightless until a magical staff gave them wings and the power of flight. The people of Avion use rocket packs for increased speed and navigation. During battle, they also carry rocket launchers and bombs. In the 80s series, Stratos sported just a few feathers on his arms and flew Superman style, with his arms straight ahead. In the 2002 series, Stratos was redrawn to have full wings and a little more heft to his frame.
