Whether it's one person or more or even a whole team of people, who would it be?

Off the top of my head I would have to say for my chooses Ashely ''Ash'' Williams from the evil dead franchise 

The Ghostbusters 

The terminator preferable the model T-101

Doc brown from the back to the future franchise 

Blade from the Blade franchise 

Mewtwo from the pokemon franchise 

Marcus Damon from Digimon Data squad 

I'll probably add more later
