Gember

Gember is the personal Gunmen belonging to General Guame. It first turns up atop the deck of the seized Dai-Gurren, where Guame boards it to personally execute the captured members of the brigade. Heavily armored and leaning on raw power, the machine lives up to its pilot's epithet, the Immovable.

Following Sayrune, Gember is the second Gunmen shown to transform. At rest it looks like a gorilla clad in orange armor and topped with long, insect-like antennae; shifted over, it turns into a giant mechanical wood louse, a face set on its back and its legs tapering into needles. Its cockpit is unlike any other in the series. Rather than a seat with twin levers, Guame curls into a rounded socket, presumably channeling his Spiral Power through it, while two mechanical hands set to either side work the machine and help him climb in and out.

The antennae bend with remarkable ease and can stretch great lengths to lash around foes and haul them about. In the louse form, the rear face can clamp down on and even swallow an enemy, though wounding its eyes forces it to release. Its finishing move, the Gember Press, called the Desperado Engrave in the movie Childhood's End, seizes the target in a crushing hug and drives home the needles that spring out of its arms.

General Guame is the only pilot Gember ever has. In its lone outing it starts strong, brushing aside Yoko's gunfire and nearly swallowing Gurren whole, holding the edge over Team Dai-Gurren. The balance flips once Simon comes back in Lagann: a re-energized Rossiu tips Gember onto its back, and the freshly combined Gurren Lagann drives Guame off by striking both eyes there. Guame counters with the Gember Press, but the rally dies fast; Gurren Lagann tears loose and finishes the machine with a Giga Drill Break. Guame himself bails out just before it blows, fleeing to Teppelin and running Dai-Gundo as his new base thereafter.

Its name comes from Genbu, the northern Black Tortoise counted among the Four Symbols of Chinese astronomy.
