Cosmo Police Galivan is an action-platform arcade game Nichibutsu released in 1985, with a protagonist able to switch between his more agile human form and a heavy combat armor with more firepower, depending on what each stretch of the level demands. It's an uncommon design for its time, combining platforming with shooting in a single versatile character.
It had a sequel, Cosmo Police Galivan II, and although it never had much impact outside Japan, it's fondly remembered by those exploring Nichibutsu's mid-80s catalog.
