You can't just make this topic out of the blue. I need days, no, weeks to figure this out.
Hm. For the record, I prefer religious or noble, evil-battling heroes, especially if they're overzealous, characters who use military martial arts or kick-based ones (muay thai, tae kwon do), characters with thrusting weapons (spears, staves, or rapiers) or moves, characters from Russia, United States, Italy, Germany, Japan, Turkey, Australia, Brazil, Cameroon, Sweden, or Scotland, characters of holy, water, plant, or ice elements, and characters who look like me or my "type" (lean muscle, tall, dark features, either very self-serious or not serious at all). I don't really care about their inputs.
Also, I won't include characters who don't originate in the canon of the games in which they star. No Strider Hiryu or Marina. Sorry.
Also, these don't relate to my favorite series/games at all. Virtua Fighter 5 is my 2nd favorite fighting game ever, but I only really like Eileen, Brad, and Lion and Eileen isn't 1 of my 5 favorites.
Also, if we could list 10, I'd have more obscure series (BEARTANK, WOO), but 5 means I have to cut Soul Calibur's Raphael (II-era would have made it) and Xiang-Hua, Capcom favorites like Mai-Ling, Iincho, Cammy, Galuda, and Daichi and Sora, A.D.K., Konami, Arcana Hearts, and older stuff.
5. Yuki from Bakumatsu Romance/The Last Blade (sorry, Shinosuke, Akari, Keiichiro, and Okina)

Bakumatsu Romance/The Last Blade series is my 5th favorite game of all-time, but the characters aren't as well-realized as other, lesser S.N.K. series. When I think of its representation of the Bakumatsu, I think of its phenomenal story, music, and backgrounds, not its character design. That said, Yuki does the Russian/snow/holy maiden/spear thing brilliantly, and she was unfairly downgraded in 2. I love her melancholic storyline and her associated aesthetics. Her ultra-defensive style serves me well.
4. Sergei Dragunov from Iron Fist/Tekken (sorry, Bruce, Emily, King, and Asuka)

He's evil, yes, but his costume and items put me in the bone zone. He matches nearly all of the criteria above AND his moveset is the best representation of sambo in fighting games. He can be super-defensive or parry-thrust, so I can adjust as needed. I adore him. His music's usually excellent, too.
3. Felicia from Vampire/Darkstalkers (sorry Aulbath, Lilith, Jon, and Sasquatch)

Wait, so, you're saying there's a Cammy-like parry-thrust character who is a nun, is good-natured, has great costume and color design, and has Vampire-incredible specials and supers? And she's in my favorite Capcom series? Sold!
2. Mary Ryan from Story Of The Hungry Wolf/Fatal Fury and The King Of Fighters (sorry Jin-Ju, Kap-Hwan, Joe, Foxy, and Elisabeth)

Even if you exclude the carried-over characters, S.N.K.'s The King Of Fighters has FAR more character designs I like than any other series. It's not even close. So, "Blue Mary"'s sambo and government official stuff isn't enough to put her on top. The Fatal Fury/The King Of Fighters crossover was more successful than most, which is appreciated but not enough. Her sad songs capture her inner spirit, but that's still not enough. I appreciate every 1 of her character designs, but that's not quite enough. Together, though, that makes for a cool character.

Perhaps it's because Bakumatsu Romance is my favorite series, but I don't really like Samurai Spirits. That said, a fictionalized Andrew Jackson president who uses a bayonet as a rapier/spear, who can do the dash-in, dash-out stuff AND defensive brilliance, who has a classic stage, song, and design, and whose story is awesome is pretty much the best thing imaginable. SALUTE, NON-AMURRICANS.
Edit: Man, there are some great choices, especially from less famous games. Also, Fersis, you are always great. louie, you are, too.
