Hercules, Tony Stark and Eros, the lil' bro of Thanos, are doing what they are usually doing: pimpin' and drink a lot of booze.
Mantis, Gamora and Moondragon, seeing of macho they are, decide that it's time to kick some ass.
Who win these matches?
Match 1: In Manhattan, no telepathy, no "giving pleasure" power for Eros and Iron Man is grounded. No Godslayer for Gamora or Mace for Herc.
Match 2: All out fight, still in Manhattan: They do whatever they want to win: Telepathy, Special power for Eros, kick in the nuts, "**** punt", etc. Iron Man can fly and rain hell if he wants. No Godslayer or mace.
Match: Same as fight 2, but Gamora and Hercules have access to their weapon.
Dude's win. I didn't even read the opening post, just the title but unless it's 1) a blow job contest, 2) a cooking contest, or 3) a contest involving house duties like fetching the damn beer or doing laundry, men win every single time. Always. It's a mathematical proven fact.
