Why these designs were included in the second installment of a successful Sega franchise remains a bit of a mystery, members of the development team acknowledging it later on but also trying to pass elements like the Godzilla boss off as a “brontosaurus” despite looking nothing like that dinosaur. On initial release, a flamethrower-wielding enemy looked a lot like Rambo, a boss character that looked like Spider-Man fired webs down at you before transforming into a flying form that looked instead like Batman, and the most flagrant of all, one boss is undeniably based on Godzilla just with his back spines missing.

The Revenge of Shinobi was reissued a few times, so depending on the version you play, you might see varying levels of copyright infringement.
