Dai-Gunten

A fortress-type Gunmen, the flying Dai-Gunten (ダイガンテン, Daiganten) is Cytomander's flagship. The Dai-Gunten made its debut during Cytomander's campaign against the Dai-Gurren, acting primarily as a carrier to launch multiple waves of small aerial Gunmen bombers. As the battle wore on, Simon and Yoko's Gurren-Lagann and Viral's Enkidu found their way deep below its decks and ended up dealing severe internal damage to the ship. Having lost altitude in the process, the Dai-Gunten was eventually damaged by a series of powerful kicks delivered by the Dai-Gurren, which had launched itself into the air using a cliff face. In the process, Team Dai-Gurren managed to snatch one of the enemy airship's two Levia-Spheres for themselves, and used it to safely float back to the ground, while the Dai-Gunten managed to retreat using the remaining one.

A month after the first confrontation, the Dai-Gunten returns in the following episode along Guame's flagship, the Dai-Gundo, as Teppelin's last line of defence against Team Dai-Gurren's invasion. Its forces managed to trap the Gurren-Lagann, after the rest of the Dai-Gurren's gunman forces were forced to retreat and protect it against Guame's offensive, and when the Shuzack was about to finish it, Simon and Rossiu were saved by some unexpected allies who entered the battlefield to aid them. In the end, the Dai-Gunten is sunk once run through by the flying Dai-Gurren. Pieces of its wreckage fell on the Dai-Gundo, provoking a massive explosion, but was unable to damage the heavily armored flagship.

Trivia

 * Dai-Gunten's design is based off of Aircraft carriers. This is also refrenced in the show as numerous Gunmen use it as a hanger.
 * The ten in the name can be translated to "sky" or "heaven", referring to it being an aerial unit.
