Kamen Rider Ginga

"I am of space and this planet's law does not apply to me. The unchangeable law that rules over the whole universe, there is only ONE!"

- Kamen Rider Ginga

"I will destroy everything you hold dear..."

- Kamen Rider Ginga upon his arrival on Earth.

Kamen Rider Ginga is a Kamen Rider from space seeking to conquer the entire universe and a major antagonist in Kamen Rider Zi-O. He is one of the Kamen Riders who emerged from the timeline created due to Sougo and Geiz's meddling. He is extremely powerful, able to easily overpower Zi-O Trinity, and because of his immense strength, he believes he has the right to rule over everything in the universe.

He is voiced by Tomokazu Sugita, who also voiced Demushu in Kamen Rider Gaim.

History
Kamen Rider Ginga arrived on Earth via a meteor during the Riders' fight against Another Kiva. Upon landing, Kamen Rider Ginga begins attacking everyone, including both the Kamen Riders and the Time Jackers and announces that he will be the one to destroy the universe. Sougo, Geiz and Woz transform into Zi-O Trinity to face him, but Kamen Rider Ginga easily overpowers Zi-O Trinity with little effort.
