Along with swagile, I too like to have my characters have one thing, one characteristic, that makes them stand out from most.
Right now, I only have one active character, named Jack Bowen.
His pride is massive to compensate for things that aren't as massive. His pride gets in the way of his normal life, and in one instance, he almost got amputated for it.
I was walking out of the ration distribution center, and another dude was walking in. We got to the doorway at the same time, and I refused to step to the side, and so did he. A unit came up to us and tried to prosecute us for something, but we persisted, and the unit must've crashed or fucked off somewhere, because he wasn't there after he issued us tags.
The standoff only ended when we glitched through each other, several minutes later.
