I also like to think, in the hypothetical Pokemon X-musical, that Xerneas’s awakening would be a fantastic affair. Like, I’m thinking Brother Bear’s Transformation here. Stunning visuals, breathtakingly beautiful music (a different set of emotions to Transformation, but just as gorgeous to listen to) and plenty of beautiful streams of light and magic coming out of Xerneas.
The room would be dark, dim and dull before Xerneas wakes up. Protag is in there on their own, basically the only significant light and colour is the glow of the ‘X’ on the tree and its reflection in the protag’s eye (interestingly the reflection makes their eye look like Xerneas’s eyes with the X for just a moment). Next minute, bam. Blue magic everywhere and Xerneas, in neutral form for a moment then suddenly transforming. Those colourful things on Xerneas’s antlers begin to grow, take colour, and twist their way through the antlers. Different colours stream out of them, winding into the blue and creating a spectrum that envelopes the dark room, blocking out Team Flare’s equipment just for a moment. The atmosphere is exciting, giving the impression that Xerneas is INCREDIBLY powerful, but a force of good.
And so darn pretty.
