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.

Every K-pop girl group and boy band has its reigning leader, from BTS' multi-talented RM to 2NE1's fiery CL, who's now a solo star but once led the (sadly defunct) fierce foursome. But which K-pop star would you place in the lead spot if you could build your own dream supergroup?

Vote for which idol should be The Leader in the Ultimate K-pop Supergroup, below, by choosing from RM, EXO's Suho and SHINee's Onew in Round 3!

Voting for Round 3, the final round, ends Sunday, April 1 at noon (EST).

Don't forget to...

The winning ultimate supergroup lineup will be announced Monday, April 2.
