iTunes wrote "Short for Best Absolute Perfect, BAP is a Korean boy band, and Warrior is its debut EP.

While the group's breakneck rapping and over-the-top imagery (check out the video) set it apart from the typical ballad-centric K-Pop offerings, BAP is most definitely a boy band, complete with matching dyed-blond hair and ultra-sleek production.

Kaylin Ro of Arirang Pop's in Seouls described "Warrior" "as a song in a new genre that blends the elements of krump and rock with an intense hip hop beat."

Ro added that "it contains a powerful message, speaking on behalf of those who face numerous challenges in their daily lives, and the spectacular performance on stage is definitely eye-catching.
