As the latest CoroCoro continue to leak online, news on another new Pokemon game have surfaced.

The new Pokemon game, according to Serebii, is titled The Band of Thieves & 1000 Pokemon. Reportedly, this game uses StreetPass to collect Pokemon to battle thieves.

What's more interesting is that the thieves in the CoroCoro leak are characters Riot and Marilyn from the upcoming Pokemon X and Y movie, "Diancie & The Cocoon of Destruction."

Marilyn Flame (and her Pokemon Delphox) is an antagonist in the Pokemon X and Y movie, and works with Ninja Riot and his Pokemon Greninja. From the "Diancie & The Cocoon of Destruction" trailer, it appears the pair are attempting to capture Diancie, but it is still a bit unclear how they figure into the movie.

The Band of Thieves & 1000 Pokemon will be available for a limited time on the Nintendo 3DS eShop in Japan starting on June 5. Reportedly, the download also offers a special Pikachu download.

Meanwhile, the Pokemon X and Y movie will be released on July 19 in Japanese theaters, and the still unreleased Pokemon Diancie will distributed in conjunction with the release.

The previous month's CoroCoro leak confirmed that the Diancie distribution event will give Pokemon fans a Level 50 Diancie, with the moves Diamond Storm, Reflect, Moonblast, and Return. It will also hold a Normal Gem.

The distribution event will be held during the theater run of the Pokemon X and Y movie from July 19 to September 30.
