Nintendo revealed that Linkle, a new original character, is going to make her debut appearance in the upcoming Hyrule Warriors Legends for 3DS.
Linkle, a character concept for the original Hyrule Warriors release, is a woman who lives in a village of cuccos and favors dual-crossbows to dispatch her enemies. She also seems to favor a color scheme evocative of Link's shades of green, but in a cloak and hood as opposed to a tunic. Her special attack is a spinning kick.
In addition to the new character, Nintendo made sure to show off that Tetra, Toon Link, Skull Kid, and King of Hyrule (from Wind Waker) were also being added to the game.
When the 3DS title releases in March 25, 2016 in North America it will be paired with a free 3DS Home Menu theme for a limited time.
