What's Your Favorite Character Theme from ANY Video Game, Show, Etc.?

[Azure Sage]

There are a bunch of them that I like. It's hard to pick just one. But I think the one that stands out to me the most is Erza Scarlet's theme from Fairy Tail. I really like the tune. There are lots of soundtracks I really like more than this that aren't character themes, though. But, from just the character themes, I think this is my favorite.

This is tough, but for me, it's definitely a tie between The Eleventh Doctor's Theme and Aang's Theme.
