Thymilph

Thymilph the Crasher (チミルフ, Chimirufu?) is the first of the Spiral King's Four Supreme Generals introduced in the story, representing the classical element of fire. He is Viral 's initial superior officer and the commander of the Human Eradication Army: Eastern Theatre, which he monitors from the deck of the land-based battleship, the Dai-Gunzan. He is good friends with Adiane, though Guame insinuates a closer relationship. He is a skilled tactician and a proud warrior, and was ultimately killed when Kamina and Simon destroyed his personal Gunmen, the Byakou, with the Giga Drill Break.

Thymilph appears as an imposingly large, well-built, armored warrior with gorilla features. He is impressively strong, almost always seen in the company of a large iron hammer he presumably uses in close-quarters combat. A seasoned and confident war veteran, Thymilph is cautious and shrewd, but like Viral, possesses a warrior's code of honor. Guame implies that Thymilph was idolized by many Beastman throughout the Beastmen Empire.

Etymology
Thymilph's name is based on the DNA chemical thymine and the elemental Sylph. His Gunmen, Byakou, is based on the mythical White Tiger, Byakko.

Beastman War Arc
During a fight between Viral and Kamina, Viral calls for help, resulting in Thymilph arriving in Dai-Gunzan. Despite Gurren Lagann's strength, the size of Dai-Gunzan makes the battle stretch in Thymilph's favor. Simon however, manages to send the mecha toppling into the canyon.

When Team Dai Gurren attacks, Thymilph sits in the cockpit of Dai-Gunzan until Simon nearly hits him with the Lagann Impact technique. Hearing the report, Thmyplih gets into his personal gunman-the Byakou-and enters the battle, attacking Kamina from below the ship's bow. Thymilph and Viral then team up and overpower Kamina, landing a serious blow that mortally wounds him.

Immediately after his victory, Thymilph is nearly hit by the Simon-controlled Dai-Gunzan, but Viral takes the hit and is sent flying. When Kamina, who survives Thymilph's attack, combines his mechas to make Gurren Lagann, Thymilph orders his remaining troops to attack. When they are defeated, Thymilph attempts to attack them himself, but fails as well.Kamina then uses the Gurren's sunglasses to hold Thymilph's Gunman for his first (and only) use of the Giga Drill Breaker technique. The attack hits and Thymiplh is killed, his Gunmen exploding a second after.

Despite his death, Thymilph still made his mark on Team Dai-Gurren. His attack on Kamina was too severe and Kamina dies immediately after his victory.

Trivia

 * Thymilph's relationship with Adiane is most likely related to the relationship between their respective DNA chemicals; thymine and adenine are always bound to one another in a DNA strand.
 * Thymilph resembles a Brute from the Halo series. Both are ape-like beings, both wield giant hammer weapons, and both rely solely on brute force in battle.
