Ultraman Belial was introduced by Tsuburaya Productions in the 2009 film Mega Monster Battle: Ultra Galaxy Legend The Movie as a former Ultra warrior corrupted by darkness and sealed away for his crimes. He quickly became one of the franchise's most recognisable villains, returning in the Ultraman Zero films and later as the central threat and genetic father of the hero in Ultraman Geed. Short clips of his processed voice and roars circulate in tokusatsu fan communities, where editors reuse them for boss fights, power scaling jokes and exaggerated villain moments.
