Solomon Grundy is a pretty powerful DC fighter, but he’s definitely not up to par with Doomsday. Doomsday may be one of the strongest comic book villains of all time in pure strength and he could easily out muscle Solomon Grundy for the win. Solomon Grundy doesn’t have Doomsday’s high level of endurance and he doesn’t have as much stamina either. Solomon Grundy just doesn’t have a shot of winning this round! Doomsday wins.
