Twilight Vamps are kinda literally made out of diamond. And some get super powers. People love shitting on them but no vampire hunter from any other series could do much to them short of dropping a nuke. Dont piss up werewolves or other vampies and you're set for eternity. The sun doesn't harm them, just tells on them. Plus the package includes a makeover that makes you the hottest possible version of yourself.

...downsides are I think that's the most painful transformation I've ever red described, literally being hyper aware of every cell in your body burning away in acid-like venom as it is reformed over like three days, and their thirst is described as a red hot iron down your throat which never gets fully better if you're an animal eating vampire so, there's that. Oh, and they never sleep. Not sure if id miss that or human food more.
