Yeah. Nova is Nova freaking Prime of the interplanetary Nova corps, a man who's held an entire civilization in his head, survived multiple galactic conflicts as a leader on the front lines, and is rebuilding an entire space militia from the ground up. He doesn't need to play second fiddle to anyone at this point, not even Captain America. And heck, I think he's probably the same age now as Cap was during the war.

So long as both characters and their abilities are treated with respect, I'm happy.
