Pokemon X and Y's Diancie event will begin on July 19 in Japan, and gamers for the first time will be able to legally obtain the character.

KPopStarz reported that this special game event will coincide with the Pokemon film, 'Diancie & the Cocoon of Destruction.' Those who buy a movie ticket will also receive the legendary Diancie. The event will last until September 30.

A short trailer has been released for "The Cocoon of Destruction and Diancie" and this time, some of the plot has been revealed. Released in Japan only, the short 90 second clip showcases Yveltal, Xerneas, Diancie, and a number of the starter Pokemon, as well as Mega Evolutions.

The movie will also feature, Ash, Bonnie, Clemont, and Serena, characters from the handheld game. According to Latin Post, the movie will focus on new legendary Diancie as it loses control of a "Holy Diamond," causing chaos to break out. Diancie will then seek the help of legendary, Xerneas, who is then attacked by Yveltal.

According to KPopStarz, X and Y's final starter evolutions, Delphox, Greninja, and Chesnaught will also be in the film along with their trainers.

The film is expected in Japanese theaters on July 19, and will then be dubbed and sent to the U.S. on Cartoon Network in October, reported Latin Post.

Pokemon has also released information about Diancie after images of the Fairy legendary appeared on the Internet after a gamer hacked X and Y and found one hidden in the coding.

"Diancie is an extremely rare Pokémon, created when Carbink undergoes a strange mutation. Its glittering pink body is said to be the most beautiful sight in the world," says the official Pokemon X and Y website.

"Diancie can create diamonds out of thin air by compressing the carbon in the atmosphere with its hands. It uses these jewels in battle to attack enemies and protect itself. Stay tuned for more information on how to get Diancie!"

Information of the movie was leaked last month along with two other hidden in game Pokemon, Volcanion and Hoopa.
