The second 10-minute demo, short as it was, held the flashier attraction: a Mega-Evolution battle that served as a hefty, story-driven boss encounter. While Arceus had plenty of big, strong Pokemon to encounter in the wild, Z-A's addition of Mega Evolution lets players face beefed-up versions of regular monsters in longer, more challenging fights.

Z-A isn't scheduled to release for another two months, Mega Dragonite is already making its franchise debut next week.
