We've reached that time of the month where Japanese magazine CoroCoro leaks and brings us all the latest Pokémon news. This month's edition is fairly quiet, but it has confirmed that the recently revealed Mewtwo relative is actually a new form for Mewtwo and not a standalone Pokémon as was first suspected because of the original official announcement stating it as a "new Pokémon".
The recent leaks haven't given much away, but they do confirm that the new form, which was revealed during Pokémon Smash, will be playing a part in the up-coming 16th movie Pokémon: Extremespeed Genesect: Mewtwo Awakens and that in the movie we will see Mewtwo awaken into this form. The form currently doesn't have a name and CoroCoro didn't reveal anything in that regard.
A new trailer for the 16th movie is due to be released later this month, so we might learn more about this Mewtwo form then. If nothing else we should get to see it in action in the trailer. Either way it's nice to finally have a few more details regarding the thing and to know it is just a new form.
