Kingslayer was released in 2020 on Bring Me The Horizon's Post Human: Survival Horror, a collaboration with Japanese group BABYMETAL that blends metalcore with electronic and J-pop elements. The opening became a favourite for short form edits because it builds and drops in under ten seconds, fitting intros and transitions perfectly. Fans of both bands shared the section across gaming, anime and fitness videos, where its recognisable pulse signals that something intense is about to happen without needing the full song.
