Dayakkaiser

The Dayakkaiser (ダヤッカイザー, Dayakkaizā) is one of Team Dai-Gurren's Gunmen units. Like most of the brigade's Gunmen, it was stolen from the Beastman Empire and customized. It has a cannon on top of its head, which fires explosive solid rounds.

It is unknown when Dayakka initially acquired this machine, but it was believed to be similar to when Kittan acquired his own Gunmen, as the two seem to know each other well. Dayakka would only pilot it a few times, most notably during the siege of the Dai-Gunzan.

When the Dai-Gunzan was captured and renamed Dai-Gurren, Dayakka was chosen to be the new battleship's captain. As such, he gave Dayakkaiser to Kittan's sister, Kiyoh. She would pilot it for the remainder of the war, mainly acting as support artillery, because Kittan was hesitant to allow her to go into the front lines.

Believed destroyed after the adoption of the Grapearls by the human military, the Dayakkaiser, among other Gunmen from Team Dai-Gurren, was in fact retrieved and maintained by Makken and Leite, who also equipped it with Spiral Energy-based weaponry. Since then, it was solely piloted by Yoko, which brought quite a shock to Dayakka when he saw it in the Arc Gurren. It was during this time that it was discovered the original Spiral King-era ganmen were all designed for space combat.

When the battle took to a grander scale, Leite managed to manufacture several Space Ganmen, ganmen on the size of warships and carried appropriately sized-up firepower. Among the Space Gunmen manufactured by Leite, Space Dayakkaiser in particular was equipped with many new weapons, such as arm-based rocket launchers and an exceedingly powerful cannon. Still piloted by Yoko (now through a cascade interface through the original Dayakkaiser as well), it served as long ranged support during the initial assault on the Anti-Spirals. Notably, it is the only Gunmen (other than the Gurren Lagann) to survive the final battle with the Anti-Spirals.
