We're down to counting hours until Pokémon X and Y's release, and despite the multitude of international retailers breaking street date and the onslaught of spoilers trickling onto the internet in the following days there's still much left unknown about the new titles. One such piece of information is the final count on Mega Evolutions, and to prove that it's still successfully kept a few secrets tucked away Nintendo unveiled a few more designs through CoroCoro Magazine.
Though they'd lacked formal announcements up until this point Mega Kangaskhan and Mega Gengar were old news, but with them came the debut of both Mega Tyranitar and Mega Aggron. The former maintains its old typings and abilities, but Mega Aggron appears to become a pure Steel-type and gains the Filter ability when it makes the change.
Once again, Pokémon X and Y. October 12th. 3DS and 2DS. I'm getting as tired of writing it as I'm sure you are of reading it.
