Return of UltramanEdit
A rat monster created by experiments by Alien Cygnus-61, Robonez was unleashed on humanity to try and kill Hideki Go (The host of Ultraman Jack) Instead, Robonez was confronted by MAT who fought hard but were unable to stop Robonez. Soon, Go had to transform into Ultraman Jack to fight it and the creature lashed out with its flames and tail, bringing the hero down and clamping onto it with his poisonous fangs. As Jack’s power began to run low, he launched his Ultra Bracelet into its jaws and Robonez was reduced to a skeleton that quickly fell part.
- Suit actor: Toya Takanobu
- Robonezu's roar are slowed down Pigmon grunts.
- Robonez's costume is a modified Kingstron suit. Extra spikes were installed on its shell and fur were glued on to its skin to give it a more mamalistic appearance. Interestingly, both kaiju suffered a similar death at the hands of Jack.
Powers and WeaponsEdit
- Poisonous Fangs: Robonez's fangs are coated with venom that can paralyze or potentially kill whatever living being he bites.
- Flames: Robonez can emit a deadly stream of fire from his mouth.
- Electric Tail: Robonez’s tail is extremely long and flexible, allowing him to use it as if a tentacle, ensnaring and throwing opponents around, or like a whip. When it has an opponent, Robonez can electrocute them with it.
