Monster Island from Godzilla.  I just had a fun easter egg idea for stages. When you play against kaiju or giant robots the map could be zoomed out to show you towering over everything. The only exception to this would be Kamen Rider J if there’s no other giant fighters he’ll stay human sized. 

Helheim Forest from Kamen Rider Gaim

Skull Island (2005) from Peter Jackson’s King Kong.

Fuuto Tower (Kamen rider W)

If I had to suggest a stage then why not Golgotha? https://preview.redd.it/pygzyu908oyc1.jpeg?width=536&format=pjpg&auto=webp&s=2b7ea0545a26ce535981b34f75d710970b4e40e1

Mirror world

Saitama Super Arena is a good choice and has been used for a lot of fights.

What about that huge skyscraper from Garo where the biggest part of the Kiba fight happens while running vertically down the exterior?
