It's not too hard to find awful subtext in a book you hate, even if said book is perfectly inoffensive.
So I try to take most of the Twilight hate with a grain of salt. Though odds are, a large fraction of it is right on the money.
Anyway, back to the actual thread topic.
You could use expies of the Cullen family. Everyone is more or less the way they are in Twilight, but worse. They try to crush problems with violence, but they kind of suck at fighting. And when you get down to it, they're cowards. Their father says don't kill and don't feed on humans, and they don't have the balls to stand up to him. Mostly, they're a bunch of low-level losers.
Which is exactly the way the their father wants it. He's a mostly decent guy who just happens to be one of the dreaded Diamond Court of vampires. Members of the Diamond Court are normally heartless monsters that make the Black Court look tame. They're stronger, faster, and tougher than any other variety of vampire. If they weren't so rare, they'd be a threat to the whole world.
But through hard work, the father has transformed his family from monsters into losers. Which is part of his plan to defang the entire Diamond Court. He's competent, dangerous, and not likely to respond well to interference with his plan. Or to the deaths of his family members.
PS: I think that
this might be relevant.
