Karn vs Shadehawk?

BEFORE Karn got his I-form???

Oh. So Shadehawk gets an ultimate weapon but Karn doesn't? That hardly seems fair. We should either consider them with all of their powers, or take away powers of equivalent value from each, since, obviously, Shadehawk is really a PC who would join the party.

Now then, as there aren't overdrives in ADV (I don't recall any), Super-Haste/Speed mode seems fair enough to take away (and it is the ultimate weapon I referred to). Karn would probably have armor of various forms, so it is reasonable to conclude that fire/thunder damage isn't a key thing here. Sonic is the only side effect Karn DOESN'T have to worry about, but the others are trouble, although they would probably consume MP. Karn has potions, etc, but those wouldn't be very effective in the long run. Explosive would probably consume MP in large amounts, because of its power. Only usable a few times, in short.

I guess it's really a tough call. But note, I'm only considering a solo battle. If all 9 ADV members were available, I think that ADV would certainly win, due to Karn's Obsessive-Compulsive behavior in collecting powerful weapons and his general preparedness with healing items, although I'm uncertain how difficult the battle would be.
