This is the first time that Lavigne's songs have been used as theme songs for a Japanese film, and the first time that a One Piece film has used songs from an overseas artist. (The television series did use Folder5's "Believe," a cover of Lolita's "Dreamin' of You.") It is also the first time that a One Piece film has had two theme songs of its own.
Lavigne is engaged to Chad Kroeger, the lead singer of Nickelback. While Lavigne had already covered Jett's "Bad Reputation" song before, One Piece Film Z will use a new recording.
One Piece Film Z will open in Japan on December 15. The film will feature "Z" (Zetto), the Straw Hat pirate crew's "strongest enemy yet" who was designed by Oda. Oda also served as the executive producer for the 10th feature film, 2009's One Piece Film Strong World.

Now I am no One Piece fan, I just found it interesting that this song will be used for an anime movie: http://www.youtube.com/watch?feature=pl ... nBWGQK67R0
But during my angsty tween years I did love to listen to Avril Lavigne, when I really didn't give a damn about my reputation, oh how the times change

So what do you guys think?
