Dark Beasts
The Dark Beasts are the giant monsters of Yodonheim that are used to invade worlds and attack cities. Each of them are based off of an aquatic animal such as a leech, crayfish, snail, black bass, giant water bug, and vampire squid. Their true faces were never revealed in the show. Although, Ligany and Basra’s faces shown were the only ones shown, but only for a short amount of time.
Jamen Beasts
The Jamen Beasts are Dark Beasts given a giant mask, called a Jamen, that gives them special abilities related to what the Jamen is based off of. Much like the Jamenshi, their special abilities come only from their Jamens.

Kudaitest Great Worlds
The Great Worlds are results of the giant combatants, Kudaitests, who have absorbed a damaged Tojiru Gear from a destroyed World Kaijin by stepping on it, giving them the head and arms of the World Kaijin as well as giving them the ability to use the power of the captured world within the Tojiru Gear.
New Kudaitest Great Worlds
The result of the New Kudaitest absorbing a Tojiru Gear, giving them the power of the captured world within the gear just like their predecessors, the Kudaitests. However, unlike the Kudaitests, they’re not mass-produced and are completely animated through cgi.
