New character biographies have been released on the Nick.com official site for The Last Airbender: Legend of Korra, including Korra, Mako, Bolin, Tenzin and Lin Beifong which give us some insight into the character's backgrounds and personalities.

Ahh! So exciting!

UPDATE: Looks like we've got some new and improved pictures of the gang. (I love Bolin's!)

UPDATE II: Three new bios are now out for Amon, Naga, and Pabu!
