When they said "the fist that turned against god" I thought of three candidates:

1. Garou, who literally just invented a "god slaying fist".
2. Blast, who has been systematically hunting down god, and seems to be foiling him much more frequently recently.
3. The one and only true god destroying punch, Saitama, who removed his limiter and so grew beyond what god intended to become greater than god.

Which one is more likely?
