What's the most messed-up family in all science fiction and fantasy?

Larger than life adventures are hard on your family life. So maybe it's no wonder that so many families in science fiction and fantasy are torn by betrayal, time-traveling incest, regular incest, monstrous transformations and deadly feuds. What's your pick for the most screwed-up family in the universe?

Please include a picture or clip of your chosen family. Also, please mention who they are, what movie/book/show/comic they come from, and why they are so dysfunctional. Thanks!
