I happen to be a pretty big fan of the short lived (literally) character of Aegis. I thought it was great that in his debut it was just street clothes that made up his costume, plus the breastplate he was destined to find; rather than just appearing with some cool super hero costume right from the start.
You can read a recap of each issue of volume 2, in which Aegis appeared, here on the site.
You can catch all of Aegis’ appearances on Corey’s New Warriors Continuity Conundrum page for Aegis.
