The character roster for Hyrule Warriors up to this point has been Zelda, Link, Impa, and Midna, leaving five more slots up for speculation.  Recently, Famitsu has revealed Lana, the White Witch who is featured in the Hyrule Warriors box art, will be a playable character.  According to Silicon Era and Game Jouhou, Lana is an original creation, and does not originate from the Zelda series, nor from the Warriors series.  The screens featured in the page reveals that Lana specializes in magical techniques (just in case you couldn’t gleam that from the term “White Witch”).  She is able to create a wall which can then be detonated to damage enemies.

If you gaze on over to the second page, you’ll notice a certain bug collector from The Legend of Zelda: Twilight Princess.  As confirmed from Silicone Era and Game Jouhou, Agatha will indeed be a playable character.  So far, all we know is that Agatha will be attacking with her parasol and is able to summon bugs.

Other details in the article reveal that characters will have access to the hookshot at some point, which will retain its use from the Zelda series as a tool to access places not reached normally.

Hyrule Warriors is set to release in the in August 14th in Japan, September 19th in Europe, September 20th in Australia, and September 26th in the United States.
