Let me drop some names… and photos.
1 - Sakura Kasugano (Street Fighter)
2 - Zero (Mega Man - specifically the Zero series)
3 - Lilith Aensland (Darkstalkers - I used Lilith instead of Morrigan because Smash IS for good boys and girls, after all… that, and because the Vampire Savior manga’s protagonist - see the character’s name or the below photo to see who I mean - needs more recognition)
4 - Shadow the Hedgehog (Sonic series, semi-clone to Sonic the Hedgehog)
5 - Either Jun Kazama or Lee Chaolan (Tekken)
6 - Rainbow Phoenix
7 - Nakoruru & Rera (Samurai Shodown - they’d work similar to both Melee & Brawl’s Zelda/Sheik and Ultimate’s Pyra/Mythra)
8 - Shadow Link (Legend of Zelda: Four Swords, semi-clone of Toon Link)
9 - Sceptile (Pokémon Ruby, Sapphire, and Emerald - just to make the Gen 3 fans happy)
10 - Terra Branford (Final Fantasy, just to make sure games in the franchise other than VII also get recognition)
That’s just my top 10, though I have PLENTY MORE in mind.
