Ah, now we're talking
Okay so, Khârn has a lot of experience as a fighter, but, not only is Jack no slouch as he's been training his entire life in the agressive art of assassination and just killing them before you can feel bad, but his attack methods of phasing in-between the Ethereal Plane and the physical world would definitely trip Khârn up as he's struggling to follow where the Hobo is coming from. Gorechild would be able to do some major damage if it hits, but, it likely wouldn't absorb the hobo considering he has pretty good resistance, which gets higher and higher as his reactive evolution does it's magic.
Speaking of reactive evolution, Khârn is basically on a time limit as per killing Jack, because eventually, his attacks aren't gonna do much, and his body will eventually give in to Jack's assaults. Though to give Khârn credit, the guy's like a frickin' Rubber Tire when you're trying to punch him. In fact, one time, he ended up getting killed, and then, literally through the power of violence, just got the fork back up. He'll be extremely difficult to kill... If not for the fact that Jack can make it easier on himself by attacking his soul so eventually, his willpower won't exactly do squat to save him.
Though, I wouldn't underestimate Khârn. He's got a lot of experience under his belt, and, if he gets a good hit on Jack with Gorechild, he may or may not outright absorb him, it's just iffy considering resistances. But, considering resistance, the fact that he can just phase in and out to trip up Khârn, soul attacks, and also, I'll now bring this up, Soul Reading allowing him to know how Khârn plans to hit him before it hits him.
So overall, not a stomp, but an unsuccessful spite.
I will vote on my own thread for reasons above.
