The Dai-Guns are battleship class gunmen that hold other gunmen inside for transport. They are massive and have heavy weapons. Four of them were given, one each, to the four beast Generals, and three belong to Lordgenome: the Arc-Gurren, the Dekabutsu, and the Cathedral Terra (later known as the Choginga Dai-Gurren). They were all originally used to fight off the anti-spirals and, as shown in Parallel Works 8, many existed, though one of each type only exist after the first war with the anti-spirals.
