Simple question. Who do you main?

Street Fighter: Juri < the evilist of the available shotos.

Tekken: Devil Jin < JACK < Bob.

Smash Bros: Wario < Sonic < Lucas. (I main Sonic, but I'm actively better with Wario.)

Psasbr: Raidec < Issac Clarke < Sackboy.

Blazblue: Arakune < Platinum.

P4AU: Haven't played much for spoilers sake, but I've taken a liking to Sho. (You put puns in a character title, I've found my main.)

StF: Fang.

Mortal Kombat: Noob Saibot < Gold Tremor < Acidic Alien.

Injustice: Lobo < Killer Frost < Zod.

Skullgirls: Fukua + Robo-Fortune.

MvC2: Venom + Blackheart + Shuma-Gorath.

UMvC3: Deadpool + Shuma-Gorath + M.O.D.O.K.

Any DBZ game: Cooler < Bardock < Future Trunks.

3rd Strike: Tweleve.

Dong Dong Never Die: Violent Dong.

Smash Bros. - Falco for Brawl and Dark Pit for 3DS

Injustice- Batman or Scorpion

MBAACC- Mecha-Hisui or Necoarc

... I don't play many fighting games.

Fighting/competitive platformer games:
Smash: Samus
BattleBlock Theater: Octopeyes
Coop Games:
Resistance 2: Medic
RWBY: Grimm Eclipse: Blake
Payday 2: Used to be Hoxton, now Ron Perlman
Other
TF2: Spy
BF4: Assault
Mario Party: Whoever is most likely to end friendships, just like the game itself.

Mortal Kombat X: Scorpion, Mileena, Kung Lao, Reptile, Jax, and Erron Black.

Skullgirls: Ms. Fortune and Double

Killer Instinct: TJ Combo, Rash, Fulgore, Arbiter, and General RAAM

Super Smash Bros: Marth, Little Mac, Mewtwo, and Luigi. Wanting to learn Bayonetta.

And it's been so long since I played UMvC3 that I forgot who I main in that one.

Smash (Brawl) -- Lucas, Ike

Smash (4) -- Ike, Robin

I don't play a lot of fighting games.

Oh boy. Just a heads up, I'm crap at more than half of these games, but I do so much love them.

Guilty Gear: Sol Badguy, all day any day (though, like everyone who's played a shoto in SF, I have a pocket Ky)

Street Fighter (Any of 'em): Ken

Smash Bros 4: Roy's my boy (Though I play pretty much any FE character at least passably, and a bit of Ryu)

Blazblue: Ragna - and maybe Naoto when CF drops.

P4AU: Whichever Sho/Minazuki had a persona, I forget which was which off the top of my head

Mortal Kombat: ... Oh man, I have NOT played much of this game. I guess the only character I even attempted a bit of learning with was Sub-Zero.

Skullgirls: Valentine + Parasoul + Beowulf

MvC2: It's been a while, but I think I used to use Gambit + Morrigan + ...Jill? Maybe. I never got seriously into any MvC game.

UMvC3: Dante + Zero + Morrigan (Side note, I have tried and failed to learn how to play MvC3 so many goddamn times)

Under Night In Birth EXE Late: Hyde

Melty Blood: Evil Shiki (Was his name just all caps SHIKI? I forget)

Soul Calibur: Mitsurugi

If I did play KI, I'd play Tusk or TJ Combo. I haven't tried the game too much since I don't have an XBone, and I haven't looked into the PC version because my fight sticks aren't recognized by the game.

If I see any more fighting games I'm into, I'll add them as we go.

For non fighting games... Used to play Scout in TF2, I tend to play Mario/Metal Mario in Mario Kart/Party/whatever games. Currently splitting my time between Reaper, Torbjorn, Hanzo, and D. Va when I play Overwatch.

I think his name was Shiki Nanaya? Which version of MB do you own?

Smash Bros: Toon Link. Sadly, he's only really viable in multiplayer with friends, or on enormous maps like Temple, because his projectile game is glorious when used right. Otherwise, I'm pretty good with Shulk. Hell, I can impersonate Shulk. I practically AM Shulk.

Touhou 7.5 IaMP: Remilia. I know there's no competitive game on this, and literally no one plays it, and I'm guessing most of you will have never HEARD of it, but hey, it's the only other fighting game I play, thought I might as well include it. Anyways, Remi's OP. And she's a vampire. That's legit all I need in a character.

Your mom

That was it. I think in one of the other games he was listed as all caps SHIKI. The version I've got is MB Actress Again Current Code (the version avaliable on steam.) I haven't played it much, but I do like the game.

Ooh goteem

I like the game alot, but man is it hard to understand. I try looking up guides for how to guard or use the arc moves, but they're not much help. I've just been button mashing the whole time.

Tekken: Bryan/Bruce > Eddy > Lili > Hwaorang (and i experiment here and there with Mardock)

Smash: equal with all the following because i rarely play smash games... Link, ROB, Duckhunt, Metaknight, Marth, Samus

Street Fighter 4: Juri > T Hawk

Street Fighter 5: Nash

Divekick: Dr Shoals > Uncle Sensei > The Fencer

Edit: so i thought we were only talking fighting games (and smash), but others are apparently branching out... I have too many games to name my mains in >.>

Smite: Ares > Rama > Poseidon > A lot of others

Starcraft 2: Protoss

Overwatch: Tanks. All of them. > Pharah > Zenyatta > pre-change-Hanzo/Mei/Junkrat/Bastion/Widowmaker all equally rarely played. > Lucio

Evilbane RPG: Luke > Lilith

Diablo 2: nothing anymore, lost my save :(
Diablo 3: barbarian > Demon Hunter

TF2: Engi > Heavy > Scout/Soldier

Halo Wars: Sgt Forge

Battlefront 2 classic: Standard trooper > Engineer
(Empire) Dark trooper

Castle Crashers: Orange knight

SWTOR: Sith Warrior > Bounty Hunter > Sith Inquisitor

Warhammer 40k: Necrons

Elder Scrolls games: Spellswords mostly

Fallout games: I tend to stick to pistols for weapons, and science/stealth for perks

SSB: Peach

...and...umm...

...Castlevania Harmony of Despair: Soma / Shanoa...?

I haven't really played a fighting game since the SNES.

SSB: ROB.
Blazblue: Picking up Jin, but mained Arakune, Lambda, Nu, Mu, Izayoi, and Hakumen.
Guilty Gear: Ramlethal, Sol, and Elphelt.
Skullgirls: Double with an optional side of Big Band.

I want to try Bang, but learning him is hard. Jin, though, is a nasty sonuvagun. He has tools for nearly everything. I will also not be picking up Street Fighter after the hilarious trainwreck 4 was.
