So Im up for this, but as a straight out warning (What I'm about to post its a real Predator but not the one I plan to choose for this [planning to play as falconer] but I does exist so you should put stipulations on the reals)

Wolf Predator

You are an extremely strong predator that has gone throw countless wars and battles. You weapons: Whip that can split an alien in half, dual shurikens, dual shoulder cannons(if you want you can convert the shoulder cannons into one gun that can kill pretty much anything), dual wrist blades and finally a jar of acid to burn up evidence of alien life on earth.
