>>28884011Gen 1 pokemon get alola forms and Z moves. They get given to you by alola Oak who gives one to you and and asks you to carry an egg for you that hatches into an alola lucario. Charizard gets two, one is exclusive to each game. Mega charizard Z is revealed and can mega evolve as well as use a Z move, it doesn't use a stone like mega rayquaza and can also hold an item. At the climax of the game you travel through one of the portals like the one UB01 comes out of in the trailer. You fight Red there with who has a lvl 100 pikachu with the catasropika z move, as well as 5 mega chariZard Zs.
Not much post game but Sinnohs battle frontier is frequently mentioned. Sinnoh remakes come out on the NX but there's no battle fronteir, only a model saying its in the works
