KotSS?

Putting that aside, I don't see how Cobra could have gotten the scar on his eye from what happened in the Nirvana arc (when Brain shot him in the back, his eye was fine).

So I strongly suspect that the things from the "Key of Starry Heaven" arc (including Cobra giving up with eyesight for the power to manipulate sound) did happen.

But that he is clothed like that is even more ridiculous than Mira and Yukino changing mid-crisis....
