''K.O. Beast'' is an anime series created by Satoru Akahori, creator of Anime/SaberMarionetteJ, with character designs by Takehito Ito, of ''[[Anime/NGKnightLamune40 Lamune & 40]]'', ''[[Anime/LordofLordsRyuKnight Ryu Knight]]'', & ''Manga/OutlawStar'' fame [[note]]The original Japanese title is ''K.O. Century Beast Musketeers''.[[/note]]

The series started as a three episode OriginalVideoAnimation, which was followed by a four episode sequel.

Thousands of years in the future, the earth is split in two. While the southern hemisphere, ruled by Czar Master, is in another dimension, the northern hemisphere is populated by tribes of humanoids who can morph into anthropomorphized beasts.

Escaping from their human captors, Wan Derbard of the Tiger tribe, Bud Mint of the Bird tribe and Mei Mer of the Mermaid tribe, along with Tuttle Millen from Mei Mer's tribe and a little girl named Yuuni Password, whose scientist grandfather wanted her safely away, seek a mysterious treasure called Gaia. Our companions have with them the Jinns, three statues-cum-machines that combine to form a HumongousMecha.

Hot on their heels are Czar Master's servants V-Darn and V-Sion as well as V-Darn's imp like companion Akumako.

The English version is something of a GagDub: the voice cast added some ''{{Anime/Pokemon}}'' references. The series was released in America by Creator/NozomiEntertainment.
