"Warrior" was lauded[citation needed] by various media outlets and netizens for its powerful and fierce imagery on its music video and live performances.

The documentary is based on the story of how six alien beings (B.A.P), who decide to become singers to dominate Earth, deal with adapting the life of a K-Pop idol.

[4] TS Entertainment wanted to debut B.A.P with a different musical direction unlike the "typical boy band route", thus coming up with the idea of dealing with the "heavy issues of our society".

A representative from TS Entertainment described "Warrior" as "a feast of splendid and grand sound combined with heart-throbbing rap and vocals".

[1] 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.

Tina Xu of MTV Korea commented, "'Warrior' features a gritty, industrial concept that clearly reflects the group’s hard, get-down-to-business image.

We’re loving their no frills, simple style of black wifebeaters paired with classic Timberlands, which, thankfully, doesn’t take away from the colorful production’s graffiti-heavy setting.

The song’s strong urban sound is further enhanced by some impressive breakdancing and step dance moves, making B.A.P quite the versatile group.

"[9] iTunes wrote "The title track sounds like something straight out of Step Up 3D, with gigantic drums, walls of synths, and a whistle punctuating the whole song"[10] Yun Seong Yeol of Star News Korea wrote, "The title song "Warrior" contains lyrics that criticize the current social system, which might be unfamiliar to many people who are used to today's friendly boy groups.

[1] Seo Mi-Yeon of TV Report Korea wrote, "'Warrior' has a fast, strong beat and its fantastic stage performance leaves an impression.
