Tengen Toppa Gurren Lagann

Tengen Toppa Gurren Lagann (天元突破グレンラガン Tengen Toppa Guren Ragan?, "Heaven-Piercing Gurren Lagann") is the titular mecha of the anime. Its design is based on the smaller Gurren Lagann and is its final form in the anime, but the movies give that title to its succeeding form, Super Tengen Toppa Gurren Lagann. By combining his own Spiral Power with his comrades, Simon created the true titular entity, which he titles, Tengen Toppa Gurren Lagann, in the final battle against Antispiral. Not actually a mecha by traditional means, the Tengen Toppa Gurren Lagann is actually a mass of continuously materialized Spiral Power (similar to the Spiral technique used to materialize Drills) on the scale of a Super Spiral galaxy.
