Can't let you do that, Samus.
Rolf, full name Rolf O' Donley, is a highly requested newcomer for Super Smash Bros for Wii U and 3DS. Both America and Japan request him all the time (Australia and Europe don't exist). There's constant requests on every site Nintendo has a profile on. One person even tried to hack Nintendo HQ to message Sakurai to add him. He's that requsted.
No, he's not Rolf from Ed, Edd, N Eddy. Not the one from Fire Emblem either. And ESPECIALLY not the one from some stupid anime you watch you fucking weaboo.
