Anti-Spiral

The Anti-Spiral Race (反螺旋族, Hanrasen Zoku, literally "Anti Spiral Tribe"?), or simply Anti-Spirals (アンチ-スパイラル, Anchisupairaru?), are a mysterious group of beings that long ago realized the danger of Spiral Nemesis and found the means to ceased their own evolution by purging themselves of spiral power, trapped in a state of suspended animation as their collective conscious took form to purge the universe of all Spiral Life.

Early History
While nothing is mentioned about how life was before they became anti-spirals, the anti-spirals were once normal spiral lifeforms. Once they realized the danger of the spiral nemesis, they halted their own evolution and purged themselves of spiral power. (It could also be assumed that those ancient Spiral's declared allegiance to the Spiral Nemesis entity after ridding themselves of their unique energy traces in order to save themselves from destruction.) They remain as white humanoid creatures with no individual identity. Their collective unconsciousness, the Anti-Spiral, continued their duty by fighting all Spiral lifeforms so that they can be limited and the spiral nemesis avoided.

First Anti-Spiral War
The Anti-Spirals found heavy resistance on Earth, since this was the home of the native Spiral warriors. The Spiral warriors held off the anti-spirals, drove them back into space and then proceeded to push further into Anti-Spiral territory.

However, with the number of Anti-Spiral's increasing as they pushed further in, the Spiral's couldn't find the location of the Anti's base of operation's, nor their home planet and soon both sides fought each other to a stalemate. This war of attrition continued until Lordgenome learned about the Spiral Nemesis and, as shown in Parallel Works episode 8, turned on the rest of the Spiral warriors in order to prevent more potential casualties. After the defeat of the Spiral Warriors of Earth, the Anti-Spiral set up numerous Human Extermination Systems all across the Earth (Some were in the form of human beings that were unaware of what they were capable of.)(See Nia Teppelin and Super Galaxy Dai-Gurren) and warned Lordgenome that if the number of human's on Earth exceeded one million, they would activated these systems and finish what they had started.

Second Anti-Spiral Arc
When the population exceeded one million, a single Mugann appeared to begin the attack while Nia, the anti-spiral's messenger, was awakened. The moon (really the Super Galaxy Dai-Gurren) began to collide with the Earth to destroy all spiral life on the planet. When Rossiu Adai attempted to escape with a small portion of the human population to space in the Arc-Gurren, they were met with an ambush of Mugann. Gurren Lagann merged with the Arc-Gurren and defeated the Mugann and reclaimed the Super Galaxy Dai-Gurren. When Team Dai-Gurren arrived in the Anti-Spirals pocket universe, the Anti-Spirals sent Ashtanga-class battleships and mass-produced Anti-Spiral mechas to fight them. They played possum with Team Dai-Gurren, then began to defeat nearly all of the veteran Gunmen pilots. They then knocked the Super Galaxy Dai-Gurren into the Death Spiral Field, causing the attempt to create the Super Galaxy Gurren Lagann to fail since the Death Spiral Field drains all occupants of Spiral Energy.

When Team Dai-Gurren escaped while also absorbing all the Spiral energy the sea had absorbed over time allowing the Super Galaxy Gurren Lagann to emerge, they tried to fight back with more Ashtanga and mass-produced Hastagry and Pada mechas, but were defeated quickly. The Anti-Spiral then sealed Team Dai-Gurren away in the Extradimensional Labyrinth. While they were trapped, the Anti-Spiral probed Nia for answers for her betrayal. Gurren Lagann appeared and rescued Nia. To counteract the newly-created Tengen Toppa Gurren Lagann, the Anti-Spiral created the Granzeboma. Despite nearly winning the battle, the Anti-Spiral lose when Simon and Nia (in Lagann) were thrown at him by Viral, and they used Lagann Impact. Before dying, they tell Simon that protecting the universe from Spiral power is up to him, before exploding.

Abilities
The Anti-Spiral have the ability to replicate Spiral lifeform traits (for example, Granzeboma and its drills). They also can create pocket universes in which they have influence over things such as probability. They can freely appear anywhere in the universe and can produce mechas for combat. They can freely move between dimensions (similar to powerful Spiral Warriors).

Appearance
The Anti-Spiral race themselves are white humanoid creatures without any distinguishing features because of their purge of Spiral Power. Their collective unconscious appears as a silhouette of a man with cartoonish facial expressions. The Anti-Spiral does not have a set shape, so it can extend seemly indefinitely.

Trivia

 * The Anti-Spirals might have something to do with Lordgenome's red Spiral energy. As seen in Parallel works 8, after conversing with the Anti-Spiral, Lordgenome's coloring changed from green to red. While they could have been done for the mood, it might also be an explanation to his unique red Spiral energy as a representation of a Spiral lifeform's falling into absolute despair.
