Multiverse Labyrinth

Multiverse Labyrinth (多元宇宙迷宮, Tagen Uchū Meikyū, lit. multiple-universe labyrinth) also known as the Extradimensional Labyrinth in English dubbed version, is a technique developed by Antispiral, where he traps the consciousnesses of the victims, by manipulating the Multiverse and exposing the victim to infinite possibilities. As possibilities are recognized, more alternate realities continue to branch. Antispiral has dropped numerous Spiral warriors up to this point and forced them into ruin. Even when a person realizes that the universe, they perceive, is a trapped universe, they become trapped in another universe upon recognition. A being can become free of the trap, but they will continue to become trapped again and again, and this goes on until infinity.

The nature of the multiverse is that the universes are always branching and progressing simultaneously at the same time where people cannot recognize it, because the "possible futures" are transformed into the "universes" as they are. The physical bodies of said "victims" are being left on their original places as Antispiral only sends their consciousnesses drifting through the infinite possibilities. As long as the target is intelligent, they cannot escape this technique unless they gain recognition of their true selves inside the space and are able to invoke Spiral Power. Simon escapes from the Multiverse Labyrinth after being made aware of his origin by the spirit of Kamina, then projects his very own Spiral Power to integrate the Multiverse and rescue the members of Team Dai-Gurren from the endless sea of possibilities.

Trivia

 * Despite common misconception, the Multiverse Labyrinth is a technique rather than a location. The already existing multiverse is exposed to the victim, having their consciousness drift throughout the endless possibilities. The Multiverse Labyrinth allows the victim's consciousness to drift through the possibilities they think of; to actually experience other universes. Without this technique, those other universes still exist, but remain unexplored.
 * The Final Drill Databook suggests that the number of multiverses are more than one, such as Simon's multiverse, Yoko's multiverse, Team Dai-Gurren's multiverse, Viral's multiverse, along with many multiverses from Spiral warriors from the past.
 * Kazuki Nakashima, whom responsible for Gurren Lagann's scripts. Believes the interpretation of the multiverse has advanced so rapidly in the last few decades, from 4-dimensional to 11-dimensional, making the Multiverse compatible with the M-theory or corresponding 11 dimensional realities.
 * These are the parallel worlds in which the Parallel Works series (aside from Episodes 8 and 9) take place.
 * The idea of the Multiverse follows the Quantum Cosmology mechanic said by Lordgenome in episode 23 where the universe only becomes a fixed reality when observed, and heavy suitable to many-worlds interpretation theory.
