On the sixth day of the battle, Dai-Gundo arrived on the battlefield after Cytomander's Dai-Gunten already engaged the humans. It deployed its own Gunman forces to bombard Dai-Gurren from below, forcing the humans' Gunmen to split up. Unfortunately for the Beastmen, one Gunman was all Team Dai-Gurren needed to devastate Cytomander's air force, allowing the rest of the heroes to attack the grounded enemies-even moreso when further human-controlled Gunmen arrived to aid Simon's air battle.
