Mikonos

Alien Baltan's henchman, an alien gorilla whose purpose is to draw out Ultraman Joneus.

• Dumb Muscle: A strong combatant, but not very bright. He's easily outmaneuvered by Ultraman Joneus during their battle. But turns out that's precisely what its boss wants.

• Killer Gorilla: A giant alien gorilla sent by Baltan to destroy cities, in order to lure Hikari into becoming Ultraman Joneus, and subsequently allowing Baltan to analyze Joneus' fighting patterns and plan a strategy.

• Pet Monstrosity: Of Alien Baltan. Note that this is perhaps the first, and only instance in the franchise where a Baltan have a pet monster (discounting Builgamo from Return of Ultraman, being a robot that isn't sentient in any way).
