The Lazengann (ラゼンガン Razengann?), meaning "Spiral Face", is Lordgenome's personal Gunman, using his consorts as batteries. It is very similar to the Gurren-Lagann and has the same abilities that the Lagann can use; by extension, it also proves immune to being controlled by the Lagann Impact attack. However, it is much stronger and can use more powerful drill techniques, as well as defend against the Gurren-Lagann's techniques with ease. In the end, it fought the Lagann on its own, which ended up severely damaged.
The mecha was later recreated as part of the Tengen Toppa Gurren-Lagann, but sacrificed by Lordgenome's desperation move Lazengann Overload which converted itself and the energy from the Granzeboma's Infinity Big Bang Storm into pure Spiral Energy, taking the form of a gigantic drill with Lordgenome's head on the tip, that is ingested by the Tengen Toppa Gurren Lagann's abdominal mouth.
Compared to Gurren-Lagann
Lazengann's spiral theme is different than that of the Lagann's: it is more jagged and square-like, compared to the smooth and more circular theme of the Lagann. Unlike the Gurren-Lagann's focus on using large, bulky Giga Drills, the Lazengann primarily uses long, slender drills that can change angles in mid-extension. Its spiral color is red, unlike the green of the Lagann's, and the spiral gauge within the cockpit rotates counter-clockwise when filling, rather than clockwise.
The Lazengann is black, with a tail used for attacks, a horned helmet, and a mouthplate on its chest armor. It can transform its entire lower body into a gigantic drill (the Gurren Lagann does the same, when docking with the Arc-Gurren). Notably, where Lazengann has one horn, Gurren Lagann has two (though it should be noted that Gurren Lagann's horns come from Enki's broken helmet).
Parallel Works 8
In the eighth Parallel Works video, it is revealed that as a child Lordgenome found a mecha very similar to Lagann. It is assumed that this mech eventually combined with another to form Lazengann, which would account for the similar energy readings to Gurren-Lagann that it emits during the battle of Teppelin.
In the same video, it is also shown that Lordgenome had his own equivalents of Arc-Gurren Lagann and Chouginga Gurren Lagann during the first Anti Spiral War, using the Dekabutsu and Cathedral Terra, respectively.
Lazengann Overload: A kamikaze move in which the Lazengann releases many drills and shoots a beam of spiral energy, but becomes unstable and may destroy itself. Once the Lazengann is destroyed, the pilot becomes one with the energy, turning it into spiral energy. The energy is then turned into the form of a drill, which can be absorbed by ally mechas.
Unnamed Giga Drill attack: Lazengann summons a massive amount of drills, then weaves them together to form a gargantuan drill larger than the Dekabutsu's head. Despite its size and strength, however, Simon (having just experienced a burst of determination and rage) was able to break the drill and damage Lazengann using only his Lagann.
Drill Bullets: Appearing only in the Otoko Series, this attack allows Lazengann to shoot bullet-shaped drill missiles. The bullets are powerful enough to temporarily down the Gurren Lagann, though it was able to get up a few seconds later.
- Lord Genome is capable of transforming Cathedral Terra into Cathedral Terra Lazengann, much like Simon turned it into Super Galaxy Gurren Lagann.
