- Super Oscillartory Ray: Mecha Gomora can charge up and fire a dark violet-colored Oscillatory Ray from his horn, like the original Gomora.
- Missiles: Mecha Gomora can fire missiles from his fingers and back.
- Mega Crusher Ray: Mecha Gomora can fire a Mega Crusher Ray from the pink light on his chest.
- Chain-Link Claws:Mecha Gomora's claws are linked to a chain that can retract and be fired from his claws via rockets.
When Reimon from an Alternate Universe was captured by the Alien Salome, his Neo Battle Nizer was confiscated and modifyed by their technology, creating Mecha Gomora as a result.
In Part I of the special, when Rei of the ZAP SPACY encounters Mecha Gomora, he send out his Gomora to do battle. However, Mecha Gomora prove to be a challenge to Gomora, and so the mechanical double easily beats down Gomora. Shortly afterwards, Ultraman Zero arrives, saving the ZAP SPACY and battles Mecha Gomora himself. The tides turn to Zero's favor as his own strength is enough to hold back Mecha Gomora on his own, destroying one of his head crest horns and both of his claws with his Zero Sluggers. Soon, Zero is confronted by the Robot Ultra Brothers and Mecha Gomora is called back for repairs, but not after taking out both Rei and Litra in the crossfire.
In Part II of the special, when Gomora attacks the Salome base, Mecha Gomora is repaired and unleashed to fight Gomora again. Much like last time, Mecha Gomora has the upper hand physically and beasts down Gomora with ease. The situation when Darklops Zero appears and calls Mecha Gomora to helping him double-team Rei's Gomora. Luckily, Ultraman Zero returns from battling the Robot Ultra Brothers and teams-up with Gomora to even the odds. With the help of both Reimons, Mecha Gomora is soon scrapped by Gomora.
- Mecha Gomora's appearance is an homage to the Toho monster, MechaGodzilla.
- Mecha Gomora's roar was made to sound more mechanic.
- During the beginning of Gomora's final battle against Mecha Gomora (while Ultraman Zero and Darklops Zero are fighting) Mecha Gomora's left head crest falls off after Gomora kicks him in the head. This is most likely a blooper that Tsuburaya tried to obscure with Darklops Zero, as Mecha Gomora's head crest reappears when fighting against Gomora again.
