I thought it was just to go hand in hand with the movie, showcasing Mewtwo's alternate form. If not, he might be used as an outlet to introduce players to Megalutions. Other than that, I have no idea. Seems kind of awkward that they'd put a lot of focus on an older Pokemon (despite the newer form) compared to the newer ones, especially the legendaries.
