First appearance: Ultra Galaxy Gaiden: Ultraman Zero vs. Darklops Zero, 2010
Belial's imitation Ultraman Zero soldiers. Darklops Zero, the prototype, first appeared in Ultraman Zero vs. Darklops Zero, whereas the finished versions first appear in massive numbers in Ultraman Zero: The Revenge of Belial.

  • Evil Knockoff: Of Zero
  • Actually a Doombot: Whilst they are always known to be robots, this trope is played with to explain their role. Zero even thinks for a brief second that Darklops Zero is a perfect copy of him, despite the clear differences Darklops Zero has.
    "I am Zero. Darklops....Zero."

Mecha Gomora

First appearance: Ultra Galaxy Gaiden: Ultraman Zero vs. Darklops Zero, 2010
Mecha Gomora is a robot replica of the original Gomora. It was once a normal Gomora that had belonged to a Rei from an alternate Universe. When the Alien Salome had kidnapped both Rei and Gomora, they took his Battle Nizer and modified it, transforming it into a robot that would serve the Alien Salome in Universal Conquest.

In part 1, the Alien Salome unleash him onto the ZAP SPACY crew when they arrive on Planet Herodia and he easily trounces Rei's Gomora in their first battle, but are forced to recall him once he gets beaten up badly by Ultraman Zero himself. In part 2, He is unleashed again when Rei and Gomora attack inside their base of operations and once again beats the crap out of Gomora. Things worsen when Darklops Zero joins the fray and they double-team Gomora for a brief bit. But Gomora is assisted by Ultraman Zero and when the Zeroes fight, Gomora is left to deal with Mecha Gomora, and with the assistance of Mecha Gomora's original owner, Mecha Gomora is destroyed.
