Karkat Vantas, also known by his Trollian handle carcinoGeneticist, is one of the trolls and one of the main characters in Homestuck.
In addition, both components of his handle serve as a form of foreshadowing, as he is a geneticist of sorts (being the creator of the pre-scratch and post-scratch trolls) and genetically breeding cancer into Bilious Slick.
His sign is called the Sign of the Signless
