As if latest single No Mercy doesn’t have enough bad boy appeal, the members of B.A.P took the tough guy act up a notch in a remix version of the song on the August 4 broadcast of MBC’s Music Core.

Don’t let their Crayola-colored wardrobe fool you, as the boys fill up the nightclub-esque stage, decorated with blinking lights, booming speakers and a line of percussionists.

Check out the high energy performance below!
