Imit-Ultraman Belial (ニセウルトラマンベリアル Nise Urutoraman Beriaru) is an Ultra created from the experimentation on Ultraman Belial's cells. While appearing similar to the former's Reionics form, he sports a yellow-gold color scheme on his crest and claws.
Wanting to defeat the Tri-Squad and Ultraman Tregear, a trio of aliens, Alien Zarab, Alien Godola and Alien Sran, sought out Alien Chibu Mabuze, who was in possession of Ultraman Belial's generic samples. Together, they created a clone of Ultraman Belial who had his template's fighting prowess, but lacked intelligence.
- Height: 55 m
- Weight: 60,000 t
- Claws: Imit-Belial's yellow-tipped claws are able to scratch and batter enemies, and are even capable of shredding Taiga Photon Earth's armor.
- Kaiser Belial Ripper (カイザーベリアルリッパー Kaizā Beriaru Rippā): Simply by swinging his claws forward, Imit-Belial can fire a series of dark crescent energy projectiles to his targets. This is based on his template's persona as Kaiser Belial.
- Claw Lightning: Imit-Belial can shoot a stream of lightning from his claws. Unlike the original's, the bolts are yellow.
- Death Light Ring (デス光輪 Desu Kōrin): Imit-Belial can launch a purple circular saw of dark energy from his hand.
- Deathcium Ray (デスシウム光線 Desushiumu Kōsen): Like the original, Imit-Belial can perform his signature Ultra Beam through the same hand maneuver.
- Due to its recent creation and lack of intelligence, this Belial simply laughs and groans in this appearance, both of which are stock voices from one of the original's voice actor, Yuki Ono.
- His yellow crest and claws are references to the defects of Alien Zarab and Gregorl-Man during their impersonations of Ultra Warriors.
- The scene in which Imit-Belial and Ultraman Titas engage in a series of rapid punches while yelling their battle cries (Ultra-ra-ra for Titas and Beli-Beli for Imit-Belial) is based on the "Stand Cries" from the Japanese manga JoJo's Bizarre Adventure.
