tip: try not to aim for the top of the head, the crown is his armor
first, when you enter the arena and he says "you've come all this way"
immediately start BOOKING it towards his throne
once you get there, try jumping on him.
after that's done, he'll be stunned (and maybe taken a bit of damage)
so now all you need to do is grab him and start punching his stomach
this is what causes most of the damage
then start throwing the props around the level (except for the fords) at king ford,
leading to stuns.
finally, punch both arms and legs, and when he's on the ground, absolutely PUNCH THE HELL out of the back of his head.

then by now, he should be dead
