I have two accounts. One is a level 81 Nord with black skin and a mohawk (named Mr.T) and the other one is a High Elf named Santas Elf. While I was playing as Santas Elf, I ran into some random bandits, and all of them were my other character.

Wouldn't it be better to have a Redguard named "Mr. T"?

I tried. He didn't look very good, so I just made a black Nord.

So you let the clone bandits live or...

If you're going to play as a bandit correctly, you must be very underpowered, use crappy weapons and armor, and talk to yourself in dungeons.

I let them live. They didn't see me, so why the hell not let my clones live?

I don't play as a bandit. My character was just cloned and the clones are bandits.

Bandit's often do have Mohawks, they could just coincidentally look like your characters...
anything abnormal that completely stuck out and confirmed that they were clones? o.o

Underpowered? No way. Bandits are exactly how they're supposed to be. Not like in Oblivion where every bandit could take on the savior of the world and had Daedric armor to boot.

How often do you see a dark skinned Nord bandit with a mohawk and a beard?

Not sure, because I can't tell whether it's a Redguard or a Nord, but plenty of Dark Skinned, Mohawk Bearded bandits.
