Azald

Azald is a cubic alien aligned with the Deathgalien and a major antagonist in Doubutsu Sentai Zyuohger. He is the leader of Team Azald in the Deathgalien's Blood Game. It is later revealed that Azald is actually Azald Legacy, an immensely powerful alien who once terrorized Zyuland long ago until he was repelled by the Zyuman Cetus with the power of Zyuoh Whale.

In the distant past, Azald Legacy attacked the Zyumans and threatened the planet. The only one willing to oppose Azald was a young whale Zyuman named Cetus whom Azald Legacy easily overpowered. However, the planet responded to Cetus's desire to protect all life and bestowed him the power of Zyuoh Whale. With his newfound powers as the original Zyuohger, Cetus used the Whale Change Gun to freeze Azald and send him into space via Cube Whale.

Hearing rumors of a monster that had been tossed into space from Earth, Ginis began searching for Azald and eventually discovered his body floating in space. Ginis attempted to remove the seal Cetus had placed on him, but this had the unintended result of causing a crystallized structure to form around Azald's body. With no memories of who he was, Azald joined the Deathgalien and swore loyalty to Ginis.
