PopCrush's K-pop March Madness 2018 is a three-week competition to determine the Ultimate K-pop Supergroup, where fans can vote for The Leader, The Rapper, The Cute One, The Edgy One, The Dancer and The Pretty Boy/Girl.

Rap and hip-hop is a major part of the K-pop industry, and most K-pop boy bands and girl groups have at least one amazing rapper on their team—from BTS' fire-spitting Suga to BLACKPINK's bilingual Lisa. But which K-pop star would you choose as the main rapper if you could build your own dream supergroup?

Vote for which idol should be The Rapper in the Ultimate K-pop Supergroup, below, by selecting from Suga, Lisa, EXO's Chanyeol, TWICE's Dahyun, BIGBANG's T.O.P, f(x)'s Amber, Block B's Zico, Seventeen's Vernon, Heize and Mark from GOT7.

Voting for Round 1 is now over! VOTE IN ROUND 2, BELOW:
