Pilot(s): Simon Nia Yoko Leeron Dayakka Gabal Attenborough Darry Gimmy Reite Tetsukan Cybella Lord Genome Viral Boota By combining his own Spiral Energy with his comrades\', Simon created the ultimate machine Tengen Toppa Gurren-Lagann in the final battle against the Anti-Spirals. Its design slightly differs from the previous forms, in that skull-like faces make up a lot of its armour. Spiral Energy burns continuously from its core, giving the mecha the appearance of the Team Dai-Gurren\'s emblem. Each of its faces holds one pilot: Simon and Nia share an altered, dual-pilot version of the Lagann\'s cockpit, and the rest of the pilots, save for Lord Genome and Viral, are placed in Lagann-style cockpits. Its abdominal mouth is clenched on the head of the Razengann, containing a fully resurrected Lord Genome. It has been confirmed in the data books that the Tengen Toppa Gurren Lagann is 10 billion light years in height. This makes it larger than the Milky Way Galaxy, and also makes it the largest mecha seen in anime to date. It also possesses a number of techniques based on the combat style of some of its multiple pilots. Source
