I was just asking because Cheren appeared in anime and when I was looking at pictures, I saw Hilbert, Hildia, and Ash togther in anime. If you have some information please post. Thanks! :)
Big pictures :3
Hilbert / Hilda are rumored to appear in the new
ExtremeSpeed Genesect: Mewtwo Awakens
Although this isn't confirmed yet by Nintendo then we cannot be sure if they will appear in the film but it is not certain.
Another point is that the film cover art has no reference to Hilda / Hilbert so it maybe unlikely they make there first appearance in Movie 16.
Hope this helps ^^
