Demon No.1 appeared in 2025 TV series called No.1 Sentai Gozyuger. Demon No.1 (鬼ノーワン Oni Nō Wan) is a demon-themed No.1 Monster from the No One World Bridan, created from Luna, Gaia Todoroki's fiancé, out of her desire to live forever and was turned into the Onigokko No.1 by Bouquet as part of a special experiment by Queen TegaJune.
Right after Onigokko No.1's defeat, Demon No.1 emerges out of said monster to make his presences known to the Gozyugers and Gaia. Upon seeing the monster, Gaia charges at the monster out of rage for taking away his fiancé, Luna.
Powers and Abilities[]
- Possession: Like all No.1 Monsters, Demon No.1 can possess a human, and materialize in the human world through their deepest desires.
- Hatred Empowerment: Due to Onigokko No.1 being used to restrain Demon No.1, the former malice ended up corrupting Demon No.1 Host, Luna. As a result, Luna's misguided rage and hatred towards Gaia ended up empowering Demon No.1 even further.
- Blaze Generation: Even without using its Crescent Sword, Demon No.1 can produce multiple Fireballs that could destroy anything.
- Size Change: Through a dark aura, Demon No.1 can grow to a giant size at will.
Arsenal[]
- Crescent Sword (三日月刀 Mikazuki Gatana): Demon No.1 wields a crescent blade in combat.
- Flame Slashes: With his Crescent Blade, Demon No.1 can generate flaming violet slashes at his enemies.
Weaknesses[]
- Hibiki No Shirabe song: Due to Demon No.1's host Luna being well versed on singing this song, anyone who can play this particular song (either by vocal or by musical arrangement) can partially bring over Luna's consciousness, rendering Demon No.1 briefly immobilized.
- Unstable Possession: According to Bouquet, Demon No.1 is deemed as an irregular amongst the other No One Monsters due to possessing the dying Luna as its host, prompting Bouquet to restrain this monster with Onigokko No.1. As a result, Demon No.1 demonstrates a berserker-like tendency, with it destroying anything and anyone it sees.
