I'm looking for spuffy fanfics with Spike at his most badass. I love it when he's sweet and loving, but when Buffy isn't getting him to be all caring and sweet I love it when he's totally badass vampire (good and evil). Any recs like that? Completed only, and very inappropriate for young audiences please!

Having a hard time with this one... The only one that comes to mind so far is tempestt's Dawn of A New Age. He's pretty badass in that one.

Thanks! I know my criteria is kind of particular, and I really appreciate the rec! I will definitely check it out
