Gurren Lagann

Gurren-Lagann is the main mecha in Tengen Toppa Gurren-Lagann. Piloted by Simon (Lagann) and Kamina(Gurren) in the first part of Part 1. Gurren was then piloted by Rossiu in the later parts of Part 1. In The second half, Gurren is piloted by Viral.



Gurren-Lagann
The Gurren Lagann (グレンラガン, Guren Ragan?), the titular mecha of the series, is piloted jointly by two pilots for most of the story, with the Lagann portion always operated by the series' main protagonist Simon and the Gurren piloted by Kamina initially and then various other characters after his death. The mech was originally formed as a hotblooded response from Kamina to the Enki's initial two-headed configuration. Later in the series the land-bound Gurren Lagann merges with another unnamed enemy Gunmen and gains a permanent set of wings. After the Battle of Tepplin, the Gurren Lagann is seen as a symbol of humanity's triumph, and later, after the AntiSpirals, preserved as one of the last true Gunman and the personal machine of Gimmy and Darry.

Its powers and fighting capabilities are almost entirely based on its ability to generate drills of greatly varying size, shape and usage from multiple points on its body. Over the course of the series Gurren Lagann produced dozens of different uses for its drills, ranging from projectiles and missiles to shields, water screws and various melee applications. The most powerful attack seen used by Gurren Lagann is the Giga Drill Break and its variants, where the pilot forms a huge amount of spiral energy into an enormous drill or number of drills bigger than the mech itself. This special trait and its status as a fused machine (with two exceptionally spirited pilots) makes it one of, if not, the most powerful entity of its size seen in the series.

Its additional abilities shown in the series include a durable energy shield, which can deflect energy blasts even at short range, the ability to wield the sunglasses on the Gurren's chest as a melee weapon (a sword or boomerang usually), a short-term regenerative function which can restore accumulated damage for the duration of the Gurren and the Lagann's union and the power to rip open a worm hole in space to travel great distances.

Lagann
The Lagann (ラガン, Ragan?) is Simon's personal Gunmen which he finds in the first episode while digging tunnels in his village. It received its name, Lagann (羅顔), meaning "enveloping face", from Kamina and draws power from the Core Drill, a small golden drill Simon used similar to an ignition key. Unlike any other Gunmen in the series, the Lagann sports a unique cockpit and stands just short of an average human adult as opposed to the others which are all mostly the sizes of small buildings or larger. This physical handicap, in tandem with the usually average level of fighting spirit supplied to it by Simon, puts the Lagann at a considerable disadvantage in single combat against enemy Gunmen. However, when Simon is driven to give his best during combat the Lagann's power increases exponentially, giving it the unique ability to generate drills from nearly any part of its frame. Lagann's other and most notable power is the "Lagann Impact", its trademark ability to combine with other machines by piercing them with its drills. It's through this ability that the titular Gurren Lagann is created, along with the other more large-scale mechas in the series.

In Gurren Lagann Parallel Works episode 8, it's revealed that the first Laganns were found by Lordgenome as a child during the Anti-Spirals' initial assault on Earth long before the series' story begins and as such were used as a basis in the creation of the all Gunmen that appear in the show to use against their enemies. While most were casted into the Galactic Spiral Abyss by the Anti-Spiral, a maddened Genome seemingly destroyed all the remaining Lagann except for the one that was placed deep underground until Simon finds it. Currently it is unknown who created the first Laganns, but it is speculated to be the Anti-Spirals (when they were still a spiral race).

Gurren
The Gurren (グレン, Guren? ), originally named the " Gunzar " as mentioned by other Beastmen in the manga, is initially an above-average size d Beastmen-piloted mecha, which attacked Litner Village the morning after Team Gurren's arrival early in the series. The mech is subsequently captured, rebuilt, stylized and named by its eventual pilot, Kamina, who had the Gurren's original swords converted into massive sunglasses similar to his own that could be used as a blade or boomerang in combat. Being of typical Gunmen proportions, the Gurren is able to fight without the Lagann's power. While its individual power was initially not on the same level as advanced Gunmen/pilot pairs, such as Viral and his Enki, Kamina eventually became experienced enough to hold his own against multiple enemies. After Kamina's death, the Gurren was mainly piloted by Rossiu and one-time pilots until the aftermath of the battle of Tepplin, pilotless until Viral becomes the Gurren's official pilot during the battle against the AntiSpirals. Gurren (紅蓮) means "Crimson Lotus". As homage to it, a white Gunzar unit is seen during the battle of Tepplin, sporting a pair of pistols rather than blades.

Arc-Gurren-Lagann
Named Arc-Gurren (アークグレン, Aku-Guren?) by Rossiu, this is one of Lordgenome's Gunmen battleships, a Dai-Gun, which his armies used when he was a Spiral Warrior in events prior to the series. Enormous in size, it is initially used to gather as hundreds of thousands of animals and people onto it as possible to escape world-destroying events later in the series. It uses Spiral Energy to run and only recognizes Lordgenome as its operator. It is capable of going into space for at least a year, and contains an array of large-scale defensive systems and weaponry.

When Simon uses the Gurren Lagann to merge into the Arc-Gurren, he converts the Dai-Gun into a Dai-Gunman called the Arc-Gurren Lagann (アークグレンラガン, Aku-Guren Ragan?), powered up by one of the Gurren Lagann's Giga Drills similar to how the Lagann is powered by Simon's Core Drill. The power of this Gunmen isn't fully displayed in the series, but it has the ability to rip the fabric of space-time itself through its sheer brute force on its debut. The Arc-Gurren Lagann is usually used exclusively by Simon and Viral, in the Gurren-Lagann. It can form massive drills or fight with punches.

The Arc Gurren-Lagann resembles the Gunbuster, another giant mecha produced by GAINAX.



Super Galaxy Gurren Lagann
The Super Galaxy Dai-Gurren (超銀河ダイグレン, Choginga Daiguren?), christened by Simon, is another colossal battleship-type Gunmen akin to the Arc-Gurren and first appeared in the prologue of the first episode before being formally introduced near the end of the third part of the series. Originally, it was called the Cathedral Terra and it was Lordgenome's flag ship against the Anti-Spirals in the past and assumed the form of moon until the climatic battle during the Anti Spirals' attack on the Arc-Gurren reveals its true identity and becomes Team Dai-Gurren's flagship for the final part of the series on their crusade to defeat the Anti-Spirals and save Nia.

Because of its size, the people on board use transportation technology to move around the ship. Its combat abilities are unparalleled by any other battleship-type mecha in the series, sporting an enormous array of missiles, beam weapons and shielding capabilities. It also has the capability to transverse to other dimensions and universes and has the manufacturing capabilities to create hundreds of Arc-Gurren Lagann-sized mecha in a small period of time.

During the final battle with the Anti-Spirals, when dealing with larger Ashtanga, Simon channeled enough massive Spiral Energy, with aid from the spiral energy of those before Team Dai-Gurren to battle the Anti-Spiral, to transform the battleship into a humanoid shape similar to the method that created the Arc-Gurren Lagann, the Trascendant Super Spiral Dreadnought Gunmen Super Galaxy Gurren Lagann (超銀河グレンラガン, Choginga Guren-Ragan?). Planetary in size, the Super Galaxy Gurren Lagann is piloted by a cascading interface of Simon piloting the Gurren Lagann, which is in turn piloting the Arc-Gurren Lagann which controls the Super Galaxy Gurren Lagann. Because it is so massive to be controlled by a single Gunman, it contains the bridge originally seen on the Super Galaxy Dai-Gurren, in order to alleviate some of the stress in piloting such a powerful mecha (although Lordgenome displayed the ability to singlehandedly control it during his reign, as he either killed or ejected anyone else on board during his takeover). Similar to the Gurren Lagann itself, The Super Galaxy Gurren Lagann sports a colossal pair of sunglasses on its torso materialized during transformation along with a smaller pair for the head.

The sheer power of this mecha shows it to be what is almost certainly the third most powerful machine in the series, capable of both deflecting and destroying objects on a planetary scale with relative ease. Like the Gurren Lagann, it also has the power to create drills from many points on its body at once and even uses a colossal version of its signature Giga Drill Break attack. On top of this, the mecha is equipped with thousands of cannons that appear from the threads of the mecha's drills (and, in some cases, within the threads of those cannons, which resembled drills), each capable of shooting a beam straight through the time-space continuum, used for hitting targets regardless of their locality and temporality in the universe.

In Gurren Lagann Parallel Works episode 8, which focused on Lord Genome's era as a Spiral Warrior, he used the Cathedral Terra in Gunman mode to wipe out the human race. Though it resembled the Super Galaxy Gurren Lagann, it lacked the sunglasses and generally resembled Lazengann. It was piloted by Lazengann inside the Dekabutsu rather than the Gurren Lagann inside the Arc-Gurren Lagann. While in battleship mode, Cathedral Terra's abilities are even more destructive, able to take down several Ashtangas and their escorts in a single blast of its mighty cannon, albet with help from the surrounding ships. Also, it appears that the Cathedral Terra is a unique ship in the Spiral Warrior's arsenal, as no other ships of this class are ever seen. In 8, Lordgenome also demonstrated his ability to use a Giga Drill Break with Cathedral Terra, hinting that this attack is an innate skill of all spiral beings, rather than a finishing move of any particular individual (as evident how Kittan's one and only attack involving spiral energy was also a Giga Drill Break).

Tengen Toppa Gurren Lagann
By combining the Spiral Power of his own and the rest of Dai-Gurren Brigade,Simon created the ultimate version of the Gurren-Lagann, the Tengen Toppa Gurren Lagann ("Heaven-Piercing Gurren Lagann").



Its size is as big as 10 Million Light Years in height(around 100 times of Milky Way)

It's actually made of many mecha combined into one(Gurren Lagann, Lazengann, etc)

Gurren-Lagann
Giga Drill Breaker Gurren-Lagann pins the opposing mecha, usually a stronger mecha, by throwing its sunglasses as a boomerang. As the sunglasses fly, they split into two. Once they have pinned the mecha in the air, Gurren-Lagann summons its giga-drill while screaming the attacks name. Gurren-Lagann then flies towards the pinned mecha, drilling straight through it. This is then quickly followed by an explosion of the pinned mecha. The sunglass boomerangs then fly back onto Gurren-Lagann's lower face, as one boomerang.

Giga Drill Maximum Gurren-Lagann surrounds itself with giga drills to do damage to all mechas around it.

Double Boomerang Gurren-Lagann removes its wings and Sunglass, then throws them both as boomerangs at the target.

Arc-Gurren-Lagann
Uppercut While not anything special, the sheer brute force of its uppercut can send a Mugann flying straight out of the universe.

Super Galaxy Gurren-Lagann
Instead of making drills out of spiral energy like other forms of Gurren-Lagann, Super Galaxy Gurren-Lagann detaches the drills on its shoulders and attaches them over its hand. These drills are placed on top of each other for a powerful Giga Drill Break.

Tengen Toppa Gurren-Lagann
My-Wife-Is-The-Best-In-The-Universe-Swing An attack named by Dayakka about his wife. Dayakka and Gabal release hooks from their respective parts of the Tengen Toppa, that tie around the opposing mecha. The Tengen Toppa then grabs the hooks' rope and swings the opposing the mecha in the air, then lets go and lets the opposing mecha fall.

Weapon Creation Gurren-Lagann can create weapons from spiral energy, such as Katanas and a Sniper Rifle, to use in combat. All of these weapons are based off characters such as the rifle from Yoko and the Katana from Viral.
