Dai-Guns are the battleship class of Gunmen, enormous carriers that hold smaller Gunmen inside for transport and carry heavy weapons. Several were spread among Lordgenome's forces and the four beast Generals.
The Dai-Guns are Gunmen of battleship scale, built large enough to ferry other Gunmen within their hulls and to bring heavy weaponry to bear. Four of them were handed out, one apiece, to the four beast Generals, while three answered to Lordgenome himself, namely the Dekabutsu, the Cathedral Terra (renamed the Choginga Dai-Gurren in time), and the Arc-Gurren.
Their original purpose was to hold off the Anti-Spirals. As glimpsed in the eighth Parallel Works short, many once existed, yet only a single example of each type remains once the first war against the Anti-Spirals has passed. Between transport, firepower, and their sheer mass, they anchor the largest engagements of the setting.
Recorded Dai-Guns include the Dai-Gunzan, the Dai-Gunten, the Dai-Gundo, and the Dai-Gunkai, plus the Dai-Gunzandu, the Doten Kaizan, and the Dai-Gunku. Lordgenome's own Arc-Gurren, Dekabutsu, and Super Galaxy Dai-Gurren round out the roster, with a Hot Spring Gunmen presumed to belong among them as well.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
