Superman vs Thor (punching contest)
Here's the setup:
Thor is chained by unbreakable bounds. How many punches does Superman need to deliver to KO him? (Superman is not holding back, and is willing to kill him).
Next, same situation but reverse the places of the heroes.
Third scenario is same as the second, except now Thor uses his hammer (for hitting only, no lightning).
Who KO's the other one faster, and how many punches do you think it will take?
