Pokkén Tournament arcade machines across Japan have now received the Halloween version update, adding Mismagius and Ninetales as Support Pokémon.
It’s also presented another surprise, in introducing players to the special Shadow Mewtwo – which appears in an Extra Battle. The requirement to encounter the Legendary Pokémon is playing a single player match, but then going on to lose two out of the three matches.
A rival Pokémon Trainer will then challenge you, who uses Shadow Mewtwo in battle. This Mega Evolves into Mega Mewtwo X at the start of the battle, which has molten rock protruding from its body.
We have no confirmation as yet whether Mewtwo will appear as a playable character in the game, but it is seemingly a given considering Bandai Namco Entertainment have implemented a complete moveset for the rival character.
