Warning: The following contains spoilers for Solo Leveling's manhwa!!AlthoughSolo Leveling's anime has shown Sung Jinwoo struggling to defeat some of his opponents, like Igris or Baran, the manhwa wasn't exactly known for having invincible villains, since after gaining more of the Shadow Monarch power, he became massively overpowered by the second part of the story. However, there's only one character in the manhwa who actually went head-to-head against Jinwoo to the point of being impossible to deal with on his own. That villain is none other than the King of Dragons and Monarch of Destruction, Antares, who still remains hidden to anime-only viewers.
