What region had the best opening within it's amount of seasons?What is that song?

I actually made a danh sách of my hàng đầu, đầu trang 10 yêu thích theme songs, bạn can view it bởi going to the bài viết section if bạn wish to. My yêu thích theme song is "We Will Carry On" from season 13. I think almost all the theme songs (with the exception of the theme from season 2 which I didn't find catchy), and "We Will Carry On" is the catchiest of all the theme songs in my opinion.

The japanese Pokemon XY: Opening 1.
FOR THE WIN!

Kanto, with the Pokemon theme song!
