Character History

Ultraman Dyna

to be added


Soon after being revealed, a group of Sphires began to attack Mars, and Terranoid was sent out to fight them. However, while Terranoid was strong and defeated most of the Sphires, the machine soon began to weaken as any real Ultra would. the Sphires overpowered the robot, merging with it and causing drastic mutations across Terranoid's entire body. Her skin grew gnarled and dark grey, and her face became heavily distorted. Wing-like spines grew out of the imitation Ultra's back, and their body grew heavy and muscular instead of the thin and lightweight body an Ultra usually has.

Now with its mind completely destroyed by the mutation, Terranoid was re-christened as Zelganoid, and began to wreak havoc across the Martian Surface, quickly setting its sights on the Black Buster Corps base.

Behind the scenes



  • Along with Algyuros's Imitation Ultraman Agul form, Terranoid (as Zelganoid) is one of the few imitation Ultras to have exhibited facial expressions. While Zelganoid violently beats Dyna down, she gives off a malevolent grin.
