"Warrior" is a song by New Zealand singer Kimbra, featuring Mark Foster of the American indie pop band Foster the People and Canadian electro house DJ A-Trak. The song was written as a part of "Three Artists, One Song", an annual series by shoe company Converse. The song was initially released as a free download in the "Three Artists, One Song" website. The song was later included in international and special editions of Kimbra's debut studio album, Vows. "Warrior" was released as the fourth single from Vows on 4 May 2012.
The music video premiered on the YouTube channel for Converse shoes on 5 April 2012. The video features a group of prisoners being forced to wrestle, and being brutally beaten, with chairs and other objects, for the enjoyment of a man wearing a red sweater. Scenes of Kimbra singing with her arms tied while watching the fight are cut into the video. At the end, the wrestlers turn on the man wearing the red jumper, and Kimbra knocks him out. The video ends with Mark Foster, Kimbra and A-Trak leaving the stadium. All of the wrestlers are wearing Converse shoes.
