Super Tengen Toppa Gurren Lagann (超天元突破グレンラガン Chō Tengen Toppa Guren Ragan?, literally "Super Heaven-Piercing Gurren Lagann"), informally known as STTGL, is a colossal, mecha-like mass of energy formed during the final battle with the Anti-Spirals in the second movie adaptation of the series, The Lights in the Sky are Stars.
After Tengen Toppa Gurren Lagann was destroyed by the Granzeboma, Team Dai-Gurren split into pieces to form their own separate Tengen Toppa Gunmen, including Tengen Toppa Gurren Lagann's head becoming Tengen Toppa Lagann. The rest of said team was composed of a Tengen Toppa Gunmen for all surviving members, along with Nia. After a lengthy battle, Lordgenome sacrificed himself to absorb the Anti-Spiral's Infinity Big Bang Storm and create a mass of Spiral Power, which Simon absorbed into the Tengen Toppa Lagann, combining with the other Tengen Toppa Gunmen to form the Super Tengen Toppa Gurren Lagann. It only appears in the second movie, and never appeared in the original television airing.
The size of STTGL is larger than our universe, according to Gurren Lagann's writer Kazuki Nakashima and the databooks. The observable universe is 93 billion light years in diameter, but the full extent of the universe's size is unknown.
STTGL thus has no officially stated quantifiable height, other than being larger than the universe. Nevertheless, STTGL's size is a significant point of discussion in the community. Due to the nature of its existence, even having a physical height itself could be considered debatable.
However, its physical size can nonetheless be estimated using available information. Estimates for its height range from at least 348.48 billion light years to 10.45 trillion light years. Compared to the observable universe, which has a diameter of 93 billion light years, the STTGL is at least 3.7 to 112 times longer than the observable universe.
According to an official guidebook, Tengen Toppa Gurren Lagann is 1025 times Gurren Lagann's height. But the guidebook is ambiguous on a few details, including Gurren Lagann's height (while the book assumes 5 meters for the Arc and Super Galaxy Gurren Lagann's heights, it's ambiguous if that applies to Tengen Toppa as well) and a potential 10x multiplier (the exact wording being "In traditional Gurren Lagann style it's multiplied by 10", with the past tense implying the mutiplication has already happened). As such, Tengen Toppa Gurren Lagann has several possible heights, ranging from 5.28 billion light years (with a 5-meter Gurren Lagann and no multiplier) to 158 billion light years (with a 15-meter Gurren Lagann and the 10x multiplier) or more.
Comparing STTGL's foot with the Granzeboma and extrapolating using the average foot-length-to-size ratio of an average person (6.6, times 10 due to Granzeboma being 1/10th STTGL's foot), the height of STTGL can be one of these values: 348.48 billion light years, 1.045 trillion light years, 3.48 trillion light years, or 10.45 trillion light years.
While there is no clearly quantifiable number for STTGL's size (other than being larger than the universe), the one-trillion-light-year figure will be used for calculations on this page.
After transforming into its drill form, its size is multiplied significantly, since its Super Tengen Toppa Giga Drill is approximately 20 times longer (approximately 20 trillion light years) and at least sixteen times wider. This gives it a volume of 1.34 duodecillion cubic light-years, or approximately 3.3 million times the volume of the observable universe.
The previous Tengen Toppa Gurren Lagann form contains within it an entire Super Spiral Space.
The Super Tengen Toppa Gurren Lagann contains the mass of the Infinity Big Bang Storm, which itself has power on par with the birth of the entire multiverse, including the Multiverse composing many higher dimensional multiverses that themselves branches infinitely with each possibility, the Super Spiral Space, and Tengen Toppa Gurren Lagann itself as its head.
Super Tengen Toppa Giga Drill clashing with the Granzeboma's equivalent collapses all the space time in the universe into a void of nothingness, similar to the Big Crunch
This form resembled an immeasurable mass of spiral power in the form of a faceless Kamina, the former pilot of Gurren, original founder of Team Gurren, and Simon's surrogate older brother, though it has "hair" closer to Simon's, complete with crimson cape and Simon's star glasses. Its size appears to be approximately 66 times taller than its preceding form, with the Granzeboma and all the Super Spiral galaxies looking tiny in comparison.
Super Tengen Toppa Giga Drill Break - Super Tengen Toppa Gurren Lagann forms a drill from Spiral Power out of its right fist (a variant of the Giga Drill Break). This drill is over 180 times larger than STTGL (in terms of cone area). When it collided with Anti-Spiral Giga Drill Break, an equivalent attack from the Super Granzeboma, they caused the very Super Spiral Space the fight was held in to collapse on itself and caused, essentially, a Big Crunch. This attack proved not strong enough to overcome the Anti-Spiral Giga Drill Break.
In addition, Super Tengen Toppa Gurren Lagann has all the abilities of previous Gurren Lagann forms. These include abilities such as reality warping, creating matter out of nothing, teleporting, traversing between dimensions and universes, and manipulating space-time and probability.
STTGL possesses the power of an infinite multiverse. Prior to the STTGL's creation, Simon had escaped from the Multiverse Labyrinth, by integrating the Multiverse itself; which contains infinite universes. In turn, absorbing the Infinity Big Bang Storm results in the creation of Super Tengen Toppa Gurren Lagann in the second film.
Super Tengen Toppa Gurren Lagann is shown to be almost equal in power to Anti-Spiral's Super Granzeboma, but falls short. Their clash caused the Anti-Spiral universe, the fight was held in, to collapse on itself. After Super Granzeboma overpowers STTGL, Anti-Spiral is defeated in the end by Simon, without relying on the mech but just using a drill he creates from his blood
STTGL's speed is practically incalculable, due to a lack of reference frames. The moment the clash occurs, it travels approximately half the length of the Giga Drill, or 10 trillion light-years, in about .2 seconds, implying its speed to be 50 trillion light-years per second, but as this only appears for a few frames, it cannot be relied upon as an accurate measure of speed.
- In theory, the Super Tengen Toppa Giga Drill Break did not fail to break the Anti-Spiral Giga Drill Break. It required the STTGL to weaken the indestructibility of the Super Granzeboma at the cost of its own structural integrity while combining (almost) every Giga Drill Break in history to finish destroying its only rival.
- Simon has inherited all of the Spiral Power that was generated by Super Tengen Toppa Gurren Lagann, allowing him to defeat Anti-Spiral, as said by Imaishi during an interview. This makes sense, as Spiral Power is generated by the pilot, not the mecha.
