Ultraman Agul is the second Ultra hero of Ultraman Gaia, the 1998 Tsuburaya Productions series and the thirteenth entry in the Ultra franchise. Bonded with the scientist Hiroya Fujimiya, Agul began as Gaia's rival before the two giants united against the planet's threats. His theme music follows the show's orchestral tokusatsu style, all bold brass and driving rhythm, and fans ripped short versions of it for transformation edits and battle tributes. Decades later the motif still signals Agul's cool, ruthless edge whenever classic Ultra clips circulate online.
