Roger Wright had designed The Starjet, a revolutionary aircraft, for the U.S. military.

In Americomics, we learn he was among the heroes who have been asleep for many years, with the complicity of Dr. Weir - Purple Claw

But there was still a good news for him. In trying to bring back Jet Girl to Dr. Weir, he made the acquaintance of Femforce
. He later learn that his sister is part of this team, to his surprise.
