Proxi

Proxi is a Fairy from. She speaks on behalf of Link, hence her name. She meets Link in Hyrule Field during The Armies of Ruins Scenario while the Dark Forces are invading the kingdom, and accompanies him after he saves her from a horde of Bokoblins. In the Majora's Mask DLC, Proxi also speaks on behalf of Young Link with the same lines she says with Link.

Trivia
