As the Pokemon X and Y movie "Cocoon of Desturction & Diancie" draws closer, a fan is showing their musical love for the newly discovered Kalos Pokemon.

From YouTuber MrLondonuts comes a self-composed theme song dedicated to the Diamond Pokemon, and it is definitely worth a listen before fans watch the Pokemon X and Y movie.

This is quite inspiring for Pokemon fans, as the Diamond & Pearl soundtrack has just been released on the iTunes music store. According to PokeJungle, it has 149 tracks, and can be purchased for $9.99.

And although there is still some ways to go before the Pokemon X and Y movie releases in Japan featuring Diancie, the anime is ongoing and earning a lot of buzz.

The most recent episode to air in Japan is episode 20 of the Pokemon X and Y movie, and it introduces Gym Leader Grant in the series.

In this episode, Ash and co. travel towards Cyllage City and encounter the Santalune City Gym Leader Viola. Viola informs them about Battle Chateau and they meet Grant. Viola and Grant battle it out at the Battle Chateau, but who will win?

You can watch the episode below thank to Pocket Monsters XY on YouTube.

What do you think of this episode? And do you think the official Diancie theme will sound as good as the fan-made contribution?
