Karkat Vantas (Homestuck)

Karkat Vantas is one of the twelve Beta Trolls in Homestuck and is the main Troll of the series. His associated Zodiac sign is Cancer, the 4th sign represented by a crab.

Why He Rocks

 * 1) Karkat Vantas is unique in that he is the only Troll whose sign is not a rainbow color (Or a shade of brown or pink), and in this case, it's gray.
 * 2) Ironically, despite being wrathful like Caliborn, he is also caring like Calliope. In fact, he types in gray like how the latter two originally did so and now type in light gray (Closer to white) and dark gray (Closer to black).
 * 3) Proof that Karkat Vantas can be caring as well is that he once gave helpful advice to Eridan Ampora, despite the hypocritical latter's desire to kill all land-dwellers.

Bad Qualities

 * 1) Karkat is quite cocky on many occaisions.
 * 2) *Of course this could do with the fact that he's crabby and being associated with the Cancer Zodiac sign.
