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 transcendent God-like being 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 had been destroyed by the Granzeboma, Team Dai-Gurren split its power 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, as well as 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 Tengen Toppa Gurren Lagann absorbed and combined into the Super Tengen Toppa Gurren Lagann. It only appears in the second movie, and never appeared in the original television series.
Super Tengen Toppa Gurren Lagann is 52.8 billion light years tall, according to the official guide book from GAINAX (仕事魂). This makes it about 58% the size of the universe, which spans 91 billion light years.
After transforming into its drill form, its size is multiplied immensely, since its Super Tengen Toppa Giga Drill is at least ten times longer (528 billion light years), and about four times wider. This gives it a cone area over 180 times the size of the Super Tengen Toppa, and a multiversal scale the size of over 100 universes.
This form resembled a 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 more than a hundred times larger than its preceding form, with the Granzeboma and all the galaxies looking tiny in comparison.
Super Tengen Toppa Gurren Lagann was lost when its Super Tengen Toppa Giga Drill Break was broken by the Super Granzeboma's Anti-Spiral Giga Drill Break. Even so, the ensuing decreasing scale of the Gurren Lagann line held off the Anti-Spiral. In the end, Simon surpassed the Anti-Spiral's power and defeated him in combat.
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. This attack proved not strong enough to overcome the Anti-Spiral Giga Drill Break, however, and only succeeded because all other forms of Gurren Lagann took its place after it was destroyed. In the end, Simon surpassed the Anti-Spiral's power and defeated him in combat.
In addition, Super Tengen Toppa has all the abilities of previous Gurren Lagann forms. These include abilities such as reality warping, creating energy and matter, teleporting, moving between dimensions and universes, punching holes through space-time, manipulating space-time and probability, and countering the manipulation of space-time and probability. Super Tengen Toppa also has the abilities of its creator and main pilot, Simon, up until that point, such as telepathy, countering mind manipulation, and erasing an entire multiverse out of existence with his thoughts.
The Super Spiral Space that the Super Tengen Toppa was fighting in is shown to be thousands of times larger than the size of Super Tengen Toppa's drill form in terms of area; since the Super Tengen Toppa Giga Drill is the size of over 100 universes, this makes the Super Spiral Space the size of a multiverse with hundreds of thousands of universes. In the clash between the Super Tengen Toppa Giga Drill and Super Granzeboma's Anti-Spiral Giga Drill, the Infinity sign appears, showing their power to be infinite, before the entire Super Spiral Space is destroyed in the clash between Super Tengen Toppa and Super Granzeboma, each shown to be nearly equal in power.
Super Tengen Toppa is shown to be almost equal in power to the Anti-Spiral's Super Granzeboma, but just slightly weaker. The only other entity more powerful than the Super Tengen Toppa is its own creator and main pilot, Simon, who later defeats the Anti-Spiral without using any mech. Simon is later shown to have the power of reviving the dead (which he refuses to abuse), and is compared to a God, implying that he is omnipotent.
The Super Tengen Toppa Giga Drill is 528 billion light years long (the length of about six universes), and STTGL can traverse that distance in under a split-second. That would make STTGL at least more than a hundred quintillion (1020) times faster than the speed of light.
