Yeah, my understanding of toon-force is that in order for it to be possible/non-hazardous it has to be funny.

A great example of toon-force in action is Ed, Edd, & Eddy. There's an episode where Ed gets a pebble in his shoe and out of misplaced anger eats a slide, or another episode where Ed is searching for someone and literally lifts a house from its foundation to look under it.
Then there's the injury shtick where pianos are dropped on heads, accordions are swallowed, or Wiley Coyote falls off of a cliff after realising he's running on thin air. They'd only be deadly if it was not funny.

Of course, that's not to say your take on toon-force is invalid. That's just the take on toon-force that I'm used to and what is generally used to describe toon-force in the subreddit r/whowouldwin.

Edit: And Harper wasn't. Deadpool's healing factor is a result of a mass of tumors that have hideously deformed him. The longer Harper lives, the more maimed he'll become.
