Mecha

Gunmen are the main type of mecha used in the anime series Tengen Toppa Gurren Lagann. The name itself means "face/facade"(顔面 ガンメン Face Surface), and can be broken down into "gun" and "man" — unsurprisingly, the mecha themselves are centered around faces and as such are very varied with few in the series being the same model. Gunmen sport a variety of weaponry: primitive models only use large clubs or bare hands, while advanced ones use solid or beam weaponry. Gunmen are powered by their human pilots' Spiral Energy(fighting spirit), or by electricity when piloted by a Beastman.

The original purpose of the Gunmen was to battle the Anti-Spirals, the main antagonistic force of the series. Lordgenome developed them about 1,000 years before the events in the series on a very large scale, with enormous Gunmen(called Dai-Guns) like the Dai-Gunzan and Arc-Gurren being much more commonplace than the smaller models seen through most of the series. Gunmen were also designed for space combat, so no further modifications were necessary when Team Dai-Gurren was launched with their Gunmen into the Earth's satellite orbit to fight the Anti-Spirals.

After the events of the series, there are very few Gunman are left in existence aside from Gurren Lagann and the Super Galaxy Dai-Gurren, with the large bulk of Earth's military being made up of Grapearls.

Gozu The first Gunmen Simon and Kamina encounter. It crashes into their village and attacks Kamina, after he antagonizes it. The mecha loses sight of Kamina, Simon and now Yoko Littner. Simon then pilots the Lagann against the Gunman, ending in its destruction. This model is likely generic since other gunman that appear like this one appear throughout the series.

Unnamed Sixteenfaced Gunmen Appearing in Episode 4, this Gunmen tried to defeat Team Gurren while Kamina was still trying to teach Simon to combine stylishly, refusing to do so unless he did it right. This is not one gunmen, but, instead, 16 Gunman merged together to create one stronger one. A mixture of Kamina's refusals to combine and Team Gurren's hunger prolonged this battle, but the battle was ended quickly once Gurren-Lagann was on the scene with well fed pilots.

Ashtanga

The Ashtanga Class (アシュタンガ級, Ashutanga Kyū?) are two dreadnaut ships which are encountered by Team Dai-Gurren in space, resembling large, rocky, roughly, spherical shape covered with multiple stone faces. They can form a powerful energy barrier that not even the Arc-Gurren Lagann could pierce with it's drill. The hands and arms surrounding the faces are not just a decoration, either. All can extend from the Ashtanga, and throw anything within reaching distance. Though there has yet to be any indication of their actual size, they are clearly shown to be many times larger than the planets around them, even throwing the planets as projectiles against the Super Galaxy Gurren Lagann before it destroyed them both. Its other attack is a massive beam, which this editor will refer to as the "Ashtanga Cannon", similar to Cathedral Terra's Helix Cannon.

The Ashtangas' design were created by manga artist, Hirohiko Araki.

Mass-Produced Anti-Spiral Mecha

These space-faring machines that emerge from the Ashtanga come in three shapes: the foot-like Pada Class (パダ級, Pada Kyū?), the hand-shaped Hastagry Class (ハスタグライ級, Hasutagurai Kyū?) and a rocket with a foresection that resembles a set of teeth. At first glance, they appear to be weaker than the Mugann, but were faking until their trap is about to spring, revealing to be much stronger than Team Dai-Gurren initially thought. After revealing their true power, they were able to destroy a number of Brigade Gunmen and their pilots, though the Space Twinboekun's massive explosion managed to take out the bulk of the armada with the surviving Dai-Gunmen destroying the rest when they attempted to force the Super Galaxy Dai-Gurren deeper into the Galactic Spiral Abyss. Several of these are seen fighting against the Lazengann in Parallel Works 8, with some models that resemble the angels from Neon Genesis Evangelion. As the Anti-Spiral have already sealed themselves on their world, it can be assumed that these are autonomous robots controlled by the Anti-Spiral avatar.

To note:

-All of the Anti-Spiral mecha outside of the Muganns and the Granzeboma produce a very unsettling moan, or disturbing laughter.

Trivia

 * Mechas in Gurren-Lagann are known as some of the weirdest looking mechas in the genre
 * All the Spiral Gunman have faces on their chests, while the Anti-Spiral mechas either have no faces ( Mugann ) or have one in its palm or toes (Mass Produced Anti-Spiral Mechas). This excludes the Grand Zamboa.
 * Some mechas make reference to previous Gainax shows. Lazengann looks like Unit 01 from Evangelion when in silhouette, for example.
 * None of the mechas in this series appear in the alternate reality manga series, Gurren Gakuen Hen
