Just a thought i had given the nature of the Protagonist and how they are essentially immortal. My main thought was how does the interceptor return to life after dying? I feel like the Protagonist is linked to Xerneas. I don't really have much to base this on other than the fact that it truly makes our hero a foil to Madame X and her Yveltal, and the dex entries for Xerneas repeatedly state it can share eternal life. Just a thought. It'd be cool if we got to fight Madame X and her Yveltal alongside Xerneas in the climax.
