Super Tengen Toppa Gurren Lagann

"We evolve beyond the person that we were a minute before. Little by little, we advance a bit further with each turn. That's how a drill works!"

- Simon

Super Tengen Toppa Gurren Lagann (超天元突破グレンラガン), informally known as STTGL, is a colossal, mech-like mass of energy formed during the final battle with Antispiral, in the second movie adaptation of the series, The Lights in the Sky are Stars.

History
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 convert Antispiral's Infinity Big Bang Storm into Spiral Energy, which Simon's Tengen Toppa Lagann absorbed, merging with the other Tengen Toppa Gunmen to form the Super Tengen Toppa Gurren Lagann.

After its formation, Antispiral transformed his Granzeboma into the Super Granzeboma, another universal scale mech, in response to the significant increase in power Team Dai-Gurren had after combining their Spiral Power. With this battle being taken on a greater scale than ever before, STTGL creates a drill, halting Super Granzeboma's own; Simon, Yoko and Nia then begin to speak to Antispiral on their ideals. Immediately after the speech is made, with all of Dai-Gurren's combined power, STTGL initiates their biggest special move "Super Tengen Toppa Giga Drill Break", to which Antispiral responded with his own Giga Drill of the same scale. The immense powers clashing together induces the Big Crunch upon Antispiral's Universe. Even with this mighty upgrade, it still wasn't enough to match Antispiral in power; smaller scale Gurren Lagann began to emerge from their bigger forms, after another. It is not until Gurren Lagann's appearance do they begin to match him, corroborated by Antispiral's shock at Gurren Lagann's pilots being able to withstand his power; perhaps the larger forms held the line, long enough for their ability to evolve to help them reach such levels of power. As Gurren Lagann breaks through Super Granzeboma's Giga Drill, the former flies in for the kill. Gurren Lagann takes much damage from their attempt to close in, however, its main pilot Simon remained unharmed, and he was the one that dealt the finishing blow to Antispiral.

After the battle had reached its conclusion, Antispiral dies. Super Tengen Toppa Gurren Lagann is also gone, along with Antispiral's Universe, and is never seen again.

Appearance
Super Tengen Toppa Gurren Lagann appears to be a Gunmen with a blue-colored universe shaped into a body, surrounding what seems to be its bones. Its shape is similar to that of its main pilot, Simon, who also has a massive head to body size ratio, only within this mech. As its body resembles the main pilot, it also retains his Star Sunglasses, albeit, with a slightly different design. However, a feature that doesn't take after Simon is its cape, which is more akin to Kamina's cape, as Simon wears a long coat (though, not at the time of this battle). A key design of this Gunmen is the Tengen Toppa Gurren Lagann that stands inside the middle of its head; the cockpit of this behemoth.

Size
The size of STTGL is larger than the observable 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 observable 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 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 taller 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 an erroneous 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 ten-trillion-light-year figure will be used for calculations of its drill form.

After transforming into its drill form, its size is multiplied significantly, since its Super Tengen Toppa Giga Drill is approximately 20 times longer (approximately 200 trillion light years) and at least sixteen times wider. This gives it a volume of approximately 1.34 Tredecillion cubic light-years, or ~1340000000000000000000000000000000000000000ly³

Powers and Abilities
Spiral Power: Super Tengen Toppa Gurren Lagann's Spiral Power is immense, as its pilots have gone through many powerups, prior to its creation. Simon integrated the multiverse itself, to his body, thereby merging all possible versions of himself throughout infinite alternate realities, along with their pasts and futures. Taking in the will of his selves, through that many realities, would boost his Spiral Power reserves to infinite levels. After appearing in front of Antispiral, he forms Tengen Toppa Gurren Lagann, which in turn, gives all members of Dai-Gurren the same power as Simon. Moments later in the battle, Tengen Toppa Gurren Lagann breaks apart into 12 different Gunmen, each of which remain as powerful as they were when they were together, via their inheritance of TTGL's generated Spiral Energy. Later on, Lordgenome with his Lazengann sacrifices himself to convert the Infinity Big Bang Storm's energy into Spiral Energy for Team Dai-Gurren to merge their Gunmen together. Super Tengen Toppa Gurren Lagann is the merging of 11 Tengen Toppa Gunmen, after Simon's distribution of this energy to everyone else. Super Tengen Toppa Giga Drill Break: This is Super Tengen Toppa Gurren Lagann's greatest attack/finishing move. Clashing with Antispiral's "Anti-Spiral Giga Drill Break", had released an immensely massive amount of energy, so much so that Antispiral's Universe collapsed into a dimensionless void, because of the incredible mass crushing the entirety of space-time itself. This is how the Spiral Nemesis is described to be the effect of; an annihilation of all reality. Although, this battle was taking place in a space-time, separated from the multiverse.

Speed
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 100 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 addition, STTGL likely has some degree of time manipulation- while this is never shown directly, the Super Galaxy Gurren Lagann was capable of firing at all points within a given region of space and time, and thus such capablities are likely both inherited and greatly enhanced- making speed calculations nigh- or outright impossible. With this, STTGL may be transcendent of the distance/time formula, which is consistent with Team Dai-Gurren and Antispiral being transcendent of time and space as well

Trivia

 * 1) Simon, and by extension all of Team Dai-Gurren, has inherited all of the Spiral Power that was generated by Super Tengen Toppa Gurren Lagann, allowing him to defeat Antispiral, as said by Imaishi during an interview. This makes sense, as Spiral Power is generated by the pilot, not the mech.
