J is uke ٩(๑❛ᴗ❛๑)۶
Lee sa-young (ML) has a wider range in his attakes, resulting in mass destruction, since he has poison abilities, the downside is that it's kinda hard to control, inhumane, and can hurt others if inhaled or touched. While Eui-jae (MC) is more on super human abilities, it's more controlled and flexible. So Eui-jae is definitely the winner plus Eui-jae is resistant to his poison, so it's useless.
(Also fun fact, in the novel, characters would nickname lee-sa-young as "240" whenever his employees would complain about him in the forums bcuz the way his name was pronounced was similar to pronunciation of the Korean letters for 2,4,0, making up "i- sa- yeoung".)
Well most likely J cuz Sayoung is weak againsts monsters that has poison immunity or inanimate objects so J is definitely more versatile. And i dont think sayoung will win against J now since he's got basilisk poison immunity.
Tho technically Sayoung could win when it comes to mass destruction/aoe cuz he's a walking biohazard lol
I really wanna see combat between j and the top just to see who’s come out on top if they went all out.
