>>57412883Fundamentally, my ideal for legendaries is that they should represent the mysticism of a world not yet fully explored or understood; the mysteries, wonders and discoveries still around in the modern age, a final frontier man has only glimpsed the fringes of and may never quite tame, the exceptional and supernatural in a world where the exceptional and supernatural is the norm. That mysticism, more than power or ability or anything else, is what you need to capture when it comes to depicting legendary Pokemon. It's what makes them what they are. Obviously, between their need to be used in marketing and overuse in villain plots, that's largely faded from canon, but you are no longer restricted by canon's bounds. If you want specific examples to crib from, the legendaries I'd study are Ho-Oh and the original Regis.
