Beastmen

Beastmen are the primary antagonists of part 1 of Gurren-Lagann. They are a blend of human and animal DNA, varrying greatly in size, shape and limbs. These hybrids served Lordgenome, their creator. They cannot produce Spiral Energy and, as such, do not set off the Human Extermination System set up by the Anti-Spiral. They also cannot reproduce and need coma-like sleep to stop from cell degeneration, unless they have an immortal body like one given to Viral. Due to their inability to produce spiral power, they pilot Gunmen by using solar powered batteries (reason gunmen don't come out at night. The two exceptions; the hot springs and the battle of Tepplin occurred cause the larger gunmen [i.e. Dekabutsu and the hot spring gunmen] supplied power to the lesser Gunmen). They do not like humans and see themselves as superior to them because of their rule over their Earth under the Spiral King, who had them kill any humans who made it to the surface. The Human Extermination Army was divided into 4 divisions, each ruled by a different General.

After Lordgenome's death, the Beastmen armies were disbanded and all Gunmen were scrapped. Many Beastmen living within Teppelin itself survived its collapse, and were persuaded by Nia Teppelin to accept peace with the human victors and were integrated into Kamina City's society without prejudice. On the outskirts of civilization, liberated Beastmen warlords continued to wage campaigns against human settlements, so battles between the New Government and Beastmen erupted over time. Seven years following the Battle of Teppelin, few if any of these resistance forces remained, most having been eliminated by Garpal Squadrons.

Trivia

 * Beastmen are showen to have no honor, showen by killing/hurting children, elderly. The Four Generals don't have honor ether, as Thymiplph double teamed and sneak attacked Kamina, Adiane and Cytomander both kidnapped someone,and Guame set traps. Howver,Viral seems to be the only Beastmen with some form of honor.
