If light of recent discussions, if Dr. Mario of all vets could return, Roy should be able to as well. He still has his distinct playstyle of "the closer you are to him, the stronger his attacks are" that none of the other swordsmen have (Ike might, but not to this obvious extreme), and with Lucina being the full-on Marth clone, Roy could be changed up like how the Project M team handled him.Do you guys think if Mewtwo returned Roy should as well?
Frankly, he could be made to be one of the most unique sword wielders; the Sword of Seals acts as both a great short-ranged AND longer-ranged weapon, able to spew fire from the blade to hit foes further from him. That'd be amazing to see incorporated. Even having his sword become engulfed in flames while he uses strong attacks would be awesome. It's a shame Sakurai doesn't see the same potential, probably still looking at him as merely an outdated promotional character. Roy's a pretty cool dude.
