Comic fan 1: I love Cyborg more than the Martian Manhunter!
Comic fan 2: I agree! Martian Manhunter is too OP in my opinion and his origin doesn't work with the knowledge we have on Mars.

Jeremy is such an op. I tried to cheat on my test, but he opped on me.

Please don’t op, bro. Don’t be a dick.
