Tengen Toppa Lagann

Simon's Tengen Toppa Gunmen comes into being during the climactic fight of the second movie, The Lights in the Sky are Stars. It begins as the head-unit of Tengen Toppa Gurren Lagann and is mended again only when it joins the other giants to form Super Tengen Toppa Gurren Lagann.

Modeled on the small Lagann that started Simon's journey, this version is essentially that cockpit blown up to enormous scale, though it keeps the ornate helmet of Tengen Toppa Gurren Lagann and a pared-down set of its shoulder guards. It is unique among the giants as the only one shaped from a fragment of the fallen flagship rather than raised anew, and it is the last of the eleven to appear. Like the original Lagann, it can sprout drills across its frame to strike.

Nia's Tengen Toppa Solvernia shields it early on, keeping the Granzeboma from boring through it. The machine then stays out of view until the reunited crew rallies, at which point it takes the full force of the Infinity Big Bang Storm head-on. When Lordgenome burns himself away to soak up that blast, the captured energy flows through this unit and the rest of the team's giants to raise their combined final form.

Simon pilots it alone. Curiously, the machine still carries every earlier stage of his mecha lineage nested inside, including Arc-Gurren Lagann and Super Galaxy Gurren Lagann, even though its outward shape borrows only from Lagann.
