Last month, the Poké Balls were concentrating on the legendary Articuno, Zapdos, Moltres, and Lugia. Now, there's a new Pokemon on the block: Mewtwo. The first appearance of Mewtwo took place during a Pokemon GO Stadium event in Yokohama, Japan.

This event, organized a year after the launch of this laureate game, hooked hundreds of people for six hours. By taking turns, and in a span of 15 minutes, the groups managed to capture all the 150 original Pokémon. Such has been the excitement that even some coaches have chosen to sell their passes to the gym doors.

Prices have reached up to 10,000 yen (77 euros).

Where is it available?

The Pokemon is currently only available in Japan, but the official website of the game indicate that, soon, the players from the West will see it too.

People could find it in the Exclusive Incursions, similar to existing ones, but with some distinction. Mewtwo will appear periodically in gyms around the world and the trainers who will be able to participate are the ones who have recently completed a successful raid on that gym. If eligible, they will receive an exclusive invitation allowing them to try their luck and increase their Pokédex.

Mewtwo will be the first Pokémon that can be captured in these incursions. There are, however, rumors about some legendary Pokemon of Generation II coming.

It now looks like Mewtwo, an extremely strong psychic Pokémon, could be the one to replace it, and become the target of the next Legendary Raid. Millions of gamers are still hooked on to Pokémon Go a year after it was first launched - and the arrival of the so-called Legendary Pokémon has given the game a new lease of life.

Legendary Raids give players a chance to catch rare Pokémon by working together to defeat gym strongholds that can be won or lost through battles.

Niantic has previously hinted that Mewtwo would be available to catch, with the character appearing right at the end of the Pokémon Go Legendary Raids trailer.

Announcing the Zapdos Legendary Raid, the company also made reference to "more legendary adventures" to come, leading many players to speculate that Mewtwo or Ho-Oh could appear next.

For the moment (trying not to have a really bitter wait), the Pokémon team has given good news. It offers coaches another chance to catch Articuno, Lugia, Moltres, and Zapdos, who will be available until August 31. So take your Poké Balls and catch 'em all!
