Assuming an average guy with standard equipment gives 9-C clubs and knifes (and similiar crude equipment). The Grinch would stomp the average guy. (and yes, I've researched stuff into the average guy a year or 2 back, and I still have scans and feats on the average human)
Composite human with standard equipment under SBA? The only thing that can be 9-B is CH's grenade (which may get up to over a megajoule). A normal car can keep up with that AP of energy, but 2 problems.
For abilities of each character:
- 1: To what extent does the Grinch have with equipment like the Paraphernalia Wagon and Dark House? It sounds like the match could be unfair.
- 2: How does the Grinch get around composite human's military-level firearms and grenades?
And did you read the composite human profile?
