I was thinking about a pretty cool concept for a Zelda game, where some of the bosses are previous incarnations of the Hero, all proper boss style. First Hero: The Hero of the Sky, Twilit Wolf: Hero of Twilight, and a two part battle against the Masked Savior: Hero of Time and the Hero's Shade
YES PLEASE! the idea of fighting a protagonist you spent time with getting stronger and stronger is like, the coolest thing to me! (best example of this would be trainer Red)
some, in particular, will make just about anything into friendly competition. Usually, something involving skills or experience. I wouldn’t say princesses though (whichever Zelda, it’s still Zelda)
