Sinestro VS Mongul (Blackest Night)
How dense must you be to fight someone using a power item that they created? Of course they would put a safeguard on it so it can’t be used against them! Mongul using how many yellow rings against Sinestro is just hilarious. I think he would have fared better using his own skillset without the rings – he did manage to take on Superman on his own after all.
