Mercer is canonically multiple tons of biomass compressed into the shape of a regular human, and the game absolutely sells that. You leave craters in the ground when you sprint, crush hoods and windshields when parkouring over traffic, can knock attack choppers out of the sky by jump kicking them, and one of your best moves against tanks is to run up a nearby building and body-slam down onto said tank, crushing it in a single blow.

I can't think of a single other game that does power fantasy better, and Prototype manages it even though Mercer is actually incredibly fragile and can die in seconds when you get into a bad spot.
