Before I say anything further, I'm not voting for anybody that's in the game as: A Pokeball, Part of a Final Smash, An Assist Trophy...etc. Otherwise I'd vote for like, Gardevoir for some Gen 3 representation. I think I'll stick to 4 votes, 2 veterans, 2 newcomers.
My votes are LIKELY for:
Roy: He deserves a chance to return, Fire Emblem swordsman or not. (although I'd prefer if he was a semi-clone). Also consider that he was planned to return alongside Mewtwo and the Doc after all. Would that make 5 Fire Emblem characters? Sure, but it's grown to an incredibly popular franchise after all.
Wolf: Shoo in, but still deserves the votes. We need our villain from Star Fox back.
Isaac from
Golden Sun: After hearing friends talking about him, and seeing him in Smash Flash 2, I feel he'd be a great character and would represent an underloved series! Plus he'd be much more unique than "A regular swordfighter."
Lana from
Hyrule Warriors: I haven't played too much of that game, but adding such a unique character like Lana into Smash would be quite interesting. I've had friends show and explain how she fights and I feel she'd fit right in. Plus, she'd diversify the Zelda lineup from just the main characters and represent a highly praised spinoff game.
This would mean we would have:
1 shiny new
Golden Sun rep. (As well as another character to be upgraded from AT to Playable, like Little Mac)
6
Legend of Zelda Reps (Ties them up with Pokemon and puts them 1 less rep behind Mario).
5
Fire Emblem Reps (Perfect amount and still stays behind the main 3 Franchises).
3
Star Fox Reps. (2 of the main heroes, and one of the main antagonists).
A thing to note about my choices is, none of them were my "personal choices" besides Isaac, and even then, I never played Golden Sun. I'm voting for who I believe are the best choices for Smash. Another thing, the only one I've voted for so far was Roy. (although I still am tempted to vote for Gardevoir, but I digress).
