Anti-Gurren Lagann

Anti-Gurren Lagann (アンチ・グレンラガン) is a mech that is exclusive to Super Robot Wars Z2: Saisei Hen. It is a dark parallel of Gurren Lagann created by Antispiral and controlled by their Messenger, Nia, to protect the inner workings of Cathedral Lazengann. It was made into an action figure by Bandai Tamashii Nations.

Appearance
As the name suggests, Anti-Gurren Lagann is almost identical to Gurren Lagann in design, but with a black, white, and red color scheme. The face on its torso has a more menacing appearance and lacks Gurren's sunglasses, while its upper face is covered with a faceplate similar to Enki’s. It also lacks the Dai-Gurren symbol on its pauldrons.

Powers and Abilities
Being based on Gurren Lagann, Anti-Gurren Lagann has similar abilities to it. However, its drills are longer and slenderer than the normal Gurren Lagann (although not to the same extent as Lazengann's), and four of them are colored purple instead of grey or green.

Trivia

 * Anti-Gurren Lagann is an original creation of Banpresto for Super Robot Wars Z2: Saisei-hen, presumably to add a proper boss fight to the end of Antispiral's attack on Earth. Following its defeat, Simon talks Nia down as he did in the anime.
 * Anti-Gurren Lagann plays a similar role to Granzeboma, being an Anti-Spiral copy of the protagonist's mech, designed to stop them from saving the Earth. Its drills also seem to echo the tentacles used by Granzeboma.
