I was watching the anime and I noticed in the episode where the meteorite was about to hit earth, Silver Fang or Bang still standing beside Genos. As far as the animated serial goes, just before Saitama is about to enter the scene, Bang's expression changes slightly as if he is about to do something.
Also, in some later episode, he hypothesizes what would have happened if he used the fist of flowing water on the meteorite? How much exactly is Bang's power and could he had destroyed the meteor?
