I've heard it was awesome and I can't wait for it to be subbed, but that's not the big news. Origins featured something new for X & Y. We have a new Mega Evolution. Slight spoilers for Pokemon Origins.

So yeah, the other Charizard I guess is officially Mega Charizard Y. Mega Charizard X is Fire/Dragon type (FINALLY!!!) with the ability Tough Claw, which increases it's physical attacks. It also receives an attack stat boost.
