There is most likely not a direct translation for "逆天" which means "breaking common sense", but I'm just curious if there is a single word that can represent that phrase.
OP( overpowered ) is pretty good I think!
It's normally used between teens and the meaning is "pretty great". For example, if you have a great performance in your study, your classmates will say "太逆天了" which means you are pretty good.
It is hard to find a eqivalent word in English. Because in different Chinese context, there are different meanings. For example,他的能力逆天了 means "he is very capable" but in some context, it means unconscionable. I (a teacher from han bridge mandarin) hope my explanation can help you.
