  • His favorite Ultraman is Ultraman Tiga and remembers watching the first three Heisei Ultraman Series in his childhood. His favorite Kaiju on the other hand is King of Mons due to its incredible strength as it took three Ultras to finish it.
    • Additionally, Ultraman Blu is the first to access his air-oriented Wind form, which uses Tiga's R/B Crystal.
