Super Galaxy Dai-Gurren

The Super Galaxy Dai-Gurren (超銀河ダイグレン, Choginga Daiguren?), christened by Simon, is another colossal battleship-type Gunmen akin to the Arc-Gurren and first appeared in the prologue of the first episode before being formally introduced near the end of the third part of the series. Originally, it was called the Cathedral Terra and it was Lordgenome's flag ship against the Anti-Spirals in the past and assumed the form of moon until the climatic battle during the Anti Spirals' attack on the Arc-Gurren reveals its true identity and becomes Team Dai-Gurren's flagship for the final part of the series on their crusade to defeat the Anti-Spirals and save Nia.

Because of its size, the people on board use teleportation technology to move around the ship. Its combat abilities are unparalleled by any other battleship-type mecha in the series, sporting an enormous array of missiles, beam weapons and shielding capabilities. It also has the capability to transverse to other dimensions and universes and has the manufacturing capabilities to create hundreds of Arc-Gurren Lagann-sized mecha in a small period of time.

During the final battle with the Anti-Spirals, when dealing with larger Ashtanga, Simon channeled enough massive Spiral Energy, with aid from the spiral energy of those before Team Dai-Gurren to battle the Anti-Spiral, to transform the battleship into a humanoid shape similar to the method that created the Arc-Gurren Lagann, the Trascendant Super Spiral Dreadnought Gunmen Super Galaxy Gurren Lagann (超銀河グレンラガン, Choginga Guren-Ragan?).
