The entity known as Bad Luck Brian (BLB) is actually a series of cloned replicants released by aliens. Whenever one dies, a replacement is wormholed in.
That's one theory - a good one - but still just one. My theory is that he's like Firefight from Brandon Sanderson's Reckoners Trilogy - every time he dies he regenerates a few hours later. Any other theories (other than these two) would be welcome (one theory per person).
