You should look at MY room.
In DK1, does the reaper looks humoruos? And doesn't he behead a knight right in the intro of the game?

I think that's pretty much a gory approach, but if that's not enough then take a close look at fights. There's enough blood to make Peter Jackson's Braindead feel like a children's tale.
DK is a gory game. It has a sense of black-humor and irony in many of its elements and for the most part is the management of a bunch of cold-blooded sadistic creatures in dungeons. Which is slightly different. If the dark mistress isn't an abomination, then what is she doing in there? And why is she called
Dark Mistress if she's supposed to be a seductive chick?
Well, I agree that she should look seductive, but a seductive abomination would be a better description of her.
