As a kid I had the reverse color Stratos and I decided he was Stratos' cousin; Tropos. (I named him after in science class I learned about the stratosphere and the troposphere.)
Exactly on it right there. We already got Tufos in the DC Universe two pack with Hawkman. Tufos is Strato's brother...that is how Matty is spinning the reverse color wings back in vintage days and today, much like the Wonder Bread Savage He-Man of vintage days, and Wun-Dar today. I just figured it out for us. Ha. Joking.
