The latest trailer shows a slightly more adult story than expected as Izel Yaotl, a jaguar-like emissary of Tezcatlipoca, the mighty warrior Zyanya, the twins Yun and K'in, and the priestess Xanastaku try and save humanity.

Onyx Equinox first popped up on our radar back in June when Crunchyroll announced it was making Sofia Alexander's (The Powerpuff Girls, Infinity Train) series.

Izel is given a magic dagger, and the blade transforms him when it gets a taste of his blood.
