Dayakkaiser

The Dayakkaiser (ダヤッカイザー, Dayakkaizā?) is the Gunman initially piloted by Dayakka, but it was transferred over to Kiyoh after he became the captain of the Dai-Gurren. Along with the other human-piloted Gunmen, this was also seized from the Beastmen Empire. It has a cannon mounted on top of its head, which fires explosive solid rounds. It is unknown when Dayakka initially aquired this machine, but it was believed to be similar to when Kittan aquired his machine, as the two seem to know eachother well. Dayakka would only pilot it a few times, notably during the siege of the Dai-Gunzan. After the Gurren Brigade aquired the Dai Gurren, Dayakka would serve as the captain of the Dai Gurren, handing the Dayakkaiser down to Kiyoh. She would pilot it for the remainder of the war, serving as support artillery (mainly because Kittan was hesitant to allow her to go into the front lines).

Believed to be 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. It was during this time that it was discovered the original Spiral King-era ganmen were all designed for space combat.

Space Dayakkaiser
When the battle took to a grander scale, Leite managed to manufacture several Space Ganmen, ganmen on the size of warships and carried apropriately 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 support artillery 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.
