Let’s suspend disbelief for a second and assume that someone like Dante from DMC can swing a greatsword as big as a human being around like it’s made of tissue paper. How strong would that person need to be or what would be the advantage of using such a heavy and huge sword? Dante is very fast with it so I’m guessing its weight wouldn’t be an issue. Dante also uses other weapons in the games, would he be more effective with another weapon? Sorry, I’ve just always wondered about that.
Granted, I’ve never played any of the Devil May Cry series. Actually, the only Capcom series I’ve got any history with is RE (and I guess Dragon’s Dogma now). That said, I’m pretty sure Dante is a half-demon, and as a result, comically strong. It’s also probably the justification for his utter disregard for the laws of physics.
Being able to toss your opponent 20 feet, or chuck a midtown bus at your foes isn’t a function of strength. That factors in, but the real problem is physics. It doesn’t really matter how strong you are, you can’t swing something that has more mass than you. At least, not the way you’d usually think of swinging a weapon. You could get into some kind of mutual dance of flying murder steel, but that’s not the same thing. This apparently isn’t an issue for Dante, because he has some supernatural control over inertia, gravity, mass manipulation, or something. Which, he’s a half demon, if that’s part of his power-set, fine, I can dig it.
