Well, then that kinda sounds like the wrong choice haha. Superman has maintained more comics than most others combined and overall was still the best selling superhero in comics as of Feb 2015 (https://www.statista.com/statistics/...g-comic-books/)
I can imagine it's important to have creators who not only have a second one in them, but a 50th versus a 10th or 20th. Not sure how much of a planet buster I'd write, but I'd try not to work myself into a corner before I can develop a classic feeling storytelling engine for my run. But if I never get to say, write a scene where he whoops Thor I'd still surely have him know the respect of planet busters.
