Ultraman Blu

Ultraman Blu is the main deutragonist of Ultraman R/B. He is the (adoptive) younger brother and partner of the protagonist of the series, Ultraman Rosso, also known as Katsumi Minato, and the tritagonist Ultrawoman Grigio, also known as Asahi Minato. Blu had a human host called Isami Minato.
Though neither siblings learned the full story behind it, Katsumi and Isami would later discover that their Ultra powers were named after their predecessors, Saki's siblings Rosso and Blu. Despite their deaths, part of them in their respective Gyro endured and subsequently chose the two as their successors. Sadly, this fateful succession of power later initially fiercely opposed by the vengeful Saki due to her denial over their sacrifice to the point of perceiving Katsumi and Isami as a stain to their predecessors' memory which didn't help by the two being coincidentally their human counterparts. It took Katsumi and Isami's determination to stop her suicidal plan against Reugocyte, their predecessors' bane and Tregear's creation, that the dying Saki eventually approved the two and chose their sister Asahi to be her heir who would later unlock the power of Ultrawoman Grigio, the very power Saki unable to access in her lifetime.
