The Brotherhood of the Shadow.
Just because... ;)

I'd travel to learn alot.
Like Shujinko in MK:D.

But I would totally start with the Brotherhood od Shadow, with the Noob Saibot of MK9.

Johnny Cage's entourage

The Deadly Alliance version of the Lin Kuei.

I would join the Shirai Ryu...before the brutal massacre of course

The Tekunin or Seidan Guardsmen.

- OIA/SF (pre-Deadly Alliance)

The Tarkatans if they don't try to kill me first.

The Lin Kuei
Tekunin
Shirai Ryu
Brotherhood of Shadow(cuz of Noob and Sareena)

The House of Elder Gods, where the biggest pain is to watch Mortal Kombat: Annihilation over and over again.

Lin Kuei all the way!

Or the guys over in Chaosrealm. It's like the fun realm. Especially since I think it would suck to live in Seido. I mean, for breaking a curfew, even if you didn't know said curfew existed, you literally stay in prison long enough to grow a long white beard. I'd go over there with all my Chaosrealm guys and...make it less sucky. See? I'm doing the Seidan people a favor here!

Then again I COULD also join Darrius' resistance...

So basically, either the Lin Kuei, Chaosrealm, or the Seidan Resistance. I'd LOVE to say Shirai Ryu, but sadly, they're all dead.

Brotherhood of shadow.

Man... this reminds me of the MKO clan days...

I was Brotherhood of Shadow then, and I'm BoS now

All Hail Shinnok...

I would probably join the Special forces team because Jax is a fucking boss.

Shirairyu as long as they are prosperous lol

...and pre 9/11....

I'm not sure. They almost all actually kind of suck.

Shirai Ryu: All dead.
Lin Kuei: Will turn you into a robot.
Brotherhood of Shadow: Evil, dead, and/or demons who have to worship Shinnok and will get betrayed by Quan Chi.
Special Forces: I don't like the idea of boot camp, I'd probably go home crying
Shao Kahn's Forces: Ultimately lose, also evil
Edenian Resistance: Also lost
Raiden's defenders: Dead
Seidan Guards: . . . Actually, they have cool armor, Seido's beautiful, and I don't really do bad things, so . . . the problem would be having to detain people for harmless mistakes
Chaosrealm: There are no factions in the realm of chaos! I'd be too busy seeing patterns and orders in everything the chaosrealmers do, thus making them wahh wahh
The Resistance: Their leader is just using them for his own quest for power/being an idol/leader
Black Dragon: Kano's cool, I guess, but I'm not particularly evil tbh, I feel bad when I hurt people's feelings
Red Dragon: Would have to change my name to KaTigeReptile
NYPD/SWAT team: From Los Angeles, sry
White Lotus Society: Not a bad choice, I guess, if they let in women. In fact, probably my favorite choice to make. But aren't they all dead, too?
Centaurs: Not a centaur
Shokan: Not a Shokan, although I could be, m i rite CaTigeReptile?
Tarkatan: Not a tarkatan
Saurian: All dead, even the Matriarch
Native American tribe(s): Not Native American/they're pretty much all dead
Vampires: All dead, right?

Maybe a god or an elder god. Hmm . . .
Who did I forget?
