King Taijitu

King Taijitu are large, serpentine creatures of Grimm that live in the Emerald Forest. It is first encountered by Lie Ren in Episode 6, who defeated two of them after a heated battle.

Appearance
The King Taijitu is one of the larger enemies seen in RWBY, easily dwarfing Lie Ren. Thus far, two types have been revealed: a black one and a white one.

The Black King Taijitu
The black King Taijitu, is primarily black in color, though it does contain a few speckles of white on its underbelly, as well as some isolated areas along its body. Its color scheme is very similar to the Beowolves and Ursa that have also been encountered in the Emerald Forest. It has large red eyes and a white bony covering with red markings on the top of its head.

The White King Taijitu
The white King Taijitu is essentially the inverse of the black King Taijitu. It also has large red eyes; however, the bony covering on the top of its head is primarily grey with red markings. Also toward the end of its body, its scales appear to have of checkerboard design of grey and white, before turning black and white, then turning completely black.

Trivia

 * Taijitu is a term that refers to the concept of Yin and Yang. It is used as the symbol of Taoism.
 * Taijitu (太極圖) roughly translates to diagram of supreme ultimate.
 * The "King" in their name may be a reference to the real-world King cobra, the world's longest venomous snake.
 * It is possible that the two snakes are somehow connected since they are both inverses of each other.
