Barca

바루카

Barca is an ice elf that appeared in the second season of Solo Leveling as the final boss of the red gate dungeon. He is a sadistic and egoistic S-rank magical beast, intelligent compared to its kind. He has blue skin and white hair and controls an army of elves. [Spoiler] He was able to defeat Kim Chul's squad and when the leader ran away he ended up facing Jin-woo. He had the upper hand at first, but was defeated after Jin-woo's shadow army defeated Barca's army and with the help of Iron and Igris. Jin-woo was not able to convert Barca to a shadow soldier.
