Karkat. He is depicted as a crabby and rude individual who spends most of his time insulting and ranting about his friends and others. He constantly uses insults and empty logic to support his arguments and often comes across as a stereotypical internet troll. In keeping with this cantankerous theme, he rarely smiles. He is not particularly patient when explaining himself and even his most sound advice can sometimes appear random and harsh. To top it off, he uses rich and imaginative language.
