I still feel kinda weird about the idea of including Western PC games into what's essentially a love-letter to Japanese console games, so I don't know how I would feel about this.
That said, if there are two characters from PC that can rightly be called iconic, it's Doomguy and some character from the Diablo/Blizzard universe. Although LucasArts comes close. Imagine Guybrush Threepwood or Sam & Max. If Doomguy makes it, I hope he's based on his older look. Nothing against the new look, but it's too gritty and realistic for Smash. The most realistic-looking character Smash has is Snake, and even then, his design remains fairly simple and doesn't look that out of place. 2016 Doom Slayer would.
At any rate, I'll certainly take Doomguy over yet more Fire Emblem or, dare I say, Skull Kid. Maybe it's just because I don't instantly love anything that comes from Zelda, but the Skull Kid rumor, if true, is so disappointing. There are so many more iconic characters that should take priority over it, especially from third parties: Billy and Jimmy Lee, Cody (Streets of Rage), Bomberman (I know he's an assist tropy shut up :( ), Master Higgins, Bonk, Crono, Akira (Virtua Fighter), Heihachi... Even Ryo Hazuki and Alex Kidd.
