The Chou Sei Shin Series (Ultra Star God Series) is a trilogy of tokusatsu shows aired from 2003-2006. Created by Toho (who famously produced the Godzilla movies) and Konami, it was their attempt to break into the Henshin Hero market that was — at the time — dominated by Toei and their two major franchises, Super Sentai and Kamen Rider, with Tsuburaya's Ultra Series for good measure. The shows revolve around the title Ultra Star Gods: Humongous Mecha that are used by the protagonists to protect the Earth from an extraterrestrial threat..
