How much KE would it take to....

[ArbitraryNumbers]

1: Casually punch someone's head off?

2: Tear someone in half?

3: Rip out a spine?

4: Cause a normal human to explode into a mess of bones?

It depends on target. However if we are talking about average 10-B- tier human i guess Wall Level is enough for first 3 , maybe room- small building for fourth one, but it's pure speculation. Of course you mean doing that thing via sheer psyhical force and wihout any weapon i guess?

Basically MK style fatalities, especially the fourth one with something like electricity manipulation.

And yes, with sheer physical force. No weapons needed.

Generally, I would go with Wall level at minimum to be on the safe side if you want to completely obliterate a person, similar to what you have mentioned.

The minimum value for Wall level starts at about 5000 joules, compared to the absolute max of Athlete level, which starts at 200 joules. That is about a 25x difference in power (easily enough to rend a regular person like butter).
