Marvel revealed a Joe Quesada Nova sketch variant cover featuring the new Nova.
At least we think it is, because it sure looks like Richard Rider albeit with a different helmet.
However, Marvel has been known to get the helmet wrong many many many times.
This also isn't the first time Loeb's new Nova has been depicted looking like an adult, I believe.
I wonder if Joe Q. had a Richard Rider sketch laying around and just switched the helmet?
