King Taijitu are large, serpentine creatures of Grimm. They appear as antagonists in RWBY and its manga adaptation.


The King Taijitu is one of the larger enemies seen in RWBY, easily dwarfing individuals like Ren. Where normal snakes have a pair of large fangs in their mouths, the Taijitu sports many fangs in its jaws, with a long, black forked tongue to boot. It has two halves, a black one and a white one, that are joined in the center.

The Black Half

The black half 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 that of the Beowolves and Ursai that have also been encountered in the Emerald Forest. It has large, blood-red eyes and a white bony covering with red markings on the top of its head.

The White Half

The white half is essentially the inverse of the black half. It also has large, blood-red eyes; however, the bony covering on the top of its head is primarily deep gray with red markings. Also, toward the end of its body, its scales appear to have a checkerboard design of gray and white, before turning black and white, then turning completely black as the other half's design comes into play.


Volume 1

In The Emerald Forest, during the Beacon Academy Initiation, Ren is ambushed by the black half of a King Taijitu. He draws StormFlower, then engages the creature. He has the upper hand and manages to wound his opponent, but then the white half joins the fray.

The white half disarms Ren, but he soon gets back up. Ren uses his Aura to defend against the black portion's attack. He then rips out both of the creature's fangs, uses one to impale the King Taijitu in the eye, then delivers a palm thrust to destroy its head in one swift blow. He then engages and defeats the white half off-screen.

Volume 2

In No Brakes, a King Taijitu was seen falling through the hole created by the blast from an exploding train. It followed the train along with the other Grimm, eventually reaching Vale to wreak havoc among its citizens.

In Breach, the very large King Taijitu emerges from the hole caused by the explosion and attacks Team RWBY. Shortly thereafter, Nora Valkyrie arrives and swiftly kills it with Magnhild.



  • Taijitu is a term that refers to the concept of Yin and Yang, the symbol of which is well known for featuring a black/white dynamic to represent duality. It is used as the symbol of Taoism.
  • Taijitu (太極圖) roughly translates to "diagram of supreme ultimate".
  • The "King" in their name is a reference to the real-life common kingsnake, which has black and white patterning.
  • In the RWBY Crew Chat between episodes Forever Fall, Pt.2 and The Stray, it was revealed that Ren fought against one King Taijitu during the Beacon Academy Initiation, rather than two, as previously thought.
  • The King Taijitu's design appears to be based off the amphisbaena, which is a type of snake-like dragon that has a head on both ends of its body.
