K-Pop Soloists just as big as their own K-Pop Group?

The biggest examples I give is Jung Kook, V and Jimin because all 3 are the biggest BTS Soloists right now.

Another biggest examples are all the BLACKPINK Soloists especially Lisa, Jennie and Rosé.

Other biggest examples:

EXO's KAI

TWICE's Nayeon

MAMAMOO's Hwasa

4minute's Hyuna (After disbandment)

SHINee's Taemin

(G)I-DLE's Yuqi

BIG BANG's Taeyang

Can you guys think of other examples of K-Pop Soloists just as big as their own K-Pop Group?

I know it can be tricky for some people.
