The T-rex would die, Grimlock would destroy them all except for Deadpool, and all of them are too small for Godzilla to zero in on and fight effectively.
it is a tie between The Nemesis and Deadpool playing Resident Evil 3 on highest difficulty is one deadly and scary son of a b!tch. don't bother fighting it until you are in the garbage area of the dead factory and shoot everything you got at it. deadpool can not die, is unpredictable, hilarious and downright crazy son of a b!tch. i enjoyed playing his game.
I am a little Star Wars bias, it's my favorite franchise, and there's so many Bounty Hunters in Star Wars it's hard not to be for this particular poll. I tried to keep all the choices to either bounty hunters, assassins, or mercenaries. That's why I kept straight pyscho killers and monsters off of the poll.
