Karkat is a candy-red-blooded mutant lowblood who's almost constantly aggravated and annoyed. He's full of sarcastic and outwitting remarks and constantly insults others in the style of a stereotypical internet troll, supporting his arguments with what seems to be empty logic. He has a soft spot and will always succumb to caring for his loved ones, however. He may just be the grouchiest troll on the planet. he gets stabbed through the chest with a pitchfork and is forced to watch his love get beat to a pulp, but hey that's life
