Richard Hatch is not just unnaturally obsessed with eyeliner, but unnaturally obsessed with the fact that he was on the original Battlestar Galactica. He's spent the intervening decades trying to get whoever would listen to remake the show and doing everything he can to keep his name alive. He's written a bunch of really crappy BSG novels as part of this, and I'm pretty sure the only reason he's on the current BSG is because they were afraid he'd otherwise sue them for daring to remake BSG without him. The guy is a loser. He shows up at science fiction conventions and gets people to pay him for his autograph, I think that's how he's avoided homelessness all these years.
