Giger ギーガー: https://vignette.wikia.nocookie.net/kamenrider/images/4... The Giger are a series of giant robots jointly developed by Zaia Enterprise and A.I.M.S. to remotely shut down large groups of HumaGears in its vicinity. Giger is a massive weapon that A.I.M.S. was developing to help them in containing rouge HumaGears by forcefully shutting down groups of them at once. Its features, as noted by Izu, bear a similarity to Breaking Mammoth in its armor form. It doesn't display the ability to transform, and is not equipped with the Mammoth Pressers on its arms. Its head instead features a single central eye.
