Though only more hardcore Zelda fans are aware of this, Impa has been in the series since the beginning. Her look shifts from game to game, like her NES/SNES era look of an elderly, wise caretaker of Princess Zelda. More fans likely recall Impa as a tough-as-nails protector in Ocarina of Time, where the badass Sheikah warrior is also guarded imbued with magical power as the Sage of Shadows. Ocarina’s characterization looks to be more of the inspiration for Hyrule Warriors’ Impa.
Impa’s outfit looks to reflect her Sheikah heritage, and she’s more than ready to kill a few thousand Stalfos to save Zelda. Based on the images, Impa’s main weapon is a massive long sword, smacking down multiple Bokoblins in one swing. And it looks like she has some great aerial combos as well, so it looks like she’ll play a little differently than Link, at least with her standard arsenal of weapons.
