Gember

Gember (ゲンバー, Genbā?) is the personal Gunmen of General Guame. It first appeared in action on the deck of the Dai-Gurren as its owner retreated to it to personally perform his public warning execution of the captured members of Team Dai-Gurren. It is the second Gunman to feature a transformation. Its normal form has the appearance of an orange-armored ape, sporting somewhat insectoid antennae which can ensnare enemies. Its alternate form is a massive wood louse with a face on its back and needle-like legs. The controls of the Gember differ from normal Gunmen to accommodate its user, as Guame is placed into a sphere-like crevice with a pair of mechanical hands aiding him. The only known attack of the Gember was its Gember Press (called "Desperado Engrave" in Childhood's End), wherein the foe is caught in a hold and crushed by the needles that are released from its arms.

Gember was short lived, as it was destroyed by the Gurren-Lagann’s Giga Drill Break. However, its pilot ejected himself before his Gunman got obliterated, retreating to the Dai-Gundo.

Eytmology
The Gember's name is based on Genbu, the Black Tortoise of the North, one of the Four Symbols of the Chinese constellations in Japanese neme.
