This unnamed man was abducted and exposed to Nebula Gas before being transformed into Nebula Hell Bro's (ネビュラヘルブロス Nebyura Heru Burosu), a prototype for the new Hell Bro's Bikaiser model developed by Nariaki Utsumi on behalf of Namba Heavy Industries Ltd..
Accompanied by a squad of Faust Guardians, Nebula Hell Bro's was sent to attack a Touto facility holding Fullbottles. He was confronted by Sento Kiryu who, recognizing the model as a Bikaiser, initially believed him to be Kaisei Mogami, the man who originally developed and used the Kaiser System to transform.
After scrapping the Guardians in ToraUFO Form, Sento assumed KirinCyclone to engage the Bikaiser before switching to KujiraJet to defeat him. With the Kaiser transformation canceled, Sento noticed he was a mere amnesiac and took him to safety. Meanwhile, Nariaki Utsumi, having used the battle to finalize the new Bikaiser he created, recovered the Nebulasteam Gun left behind by the Nebula Hell Bro's which, upon inserting the Remocon and Engine Gears, transformed him into the complete Bikaiser Hell Bro's.

Nebula Hell Bro's (ネビュラヘルブロス Nebyura Heru Burosu) is the prototype of the Hell Bro's Bikaiser.
Unlike the completed Kaisers, the Nebula Hell Bro's is more similar to the non-Hard Smash in that the transformed subject's memory is wiped. As such, their awareness is impaired and they are compelled to rampage.
