The largest mecha in the Tengen Toppa Gurren Lagann series, introduced in Lagann-hen, Chou Tengen Toppa Gurren Lagann is a manifestation of pure Spiral Power, vaguely resembling both Kamina and Simon, created with the fusion of all the Tengen Toppa Gunmen. It is at least 50 times larger than Tengen Toppa Gurren-Lagann, approaching the size of a galactic cluster, thus making it one of the largest mecha in anime to date.
Its signature attack, Chou Tengen Toppa Giga Drill Breaker, is several times larger and more powerful still than the mecha itself, enough to infinitely distort the Anti-Spiral's dimension and destroy it as a result.
