Tengen Toppa Lagann (天元突破ラガン Tengen Toppa Ragan, literally "Heaven-Piercing Lagann") is Simon's Tengen Toppa Gunmen formed during the final battle with the Granzeboma in the second movie adaptation of the series, The Lights in the Sky are Stars. It is the head-unit of Tengen Toppa Gurren Lagann, which is broken off when the premiere Tengen Toppa Gunmen is destroyed. It is later repaired when it is used with the other Tengen Toppa Gunmen to form Super Tengen Toppa Gurren Lagann.
