10 Worst Things Harley Quinn Has Done To The Joker
6. Trying To Kill Him - Batman: Prelude To The Wedding
While the majority of Batman: Preludes to the Wedding is focused, unsurprisingly, on the Dark Knight and Catwoman preparing to get married, other storylines do make an entrance. The best of these by a long shot has to be seeing Harley try to stone cold murder her former lover.
Because Harley doesn't just try and kill the Joker in a regular fashion. No, she instead decides that she simply must murder him by drowning him in tapioca - the type of pudding that her "puddin'" hates most.
This fails, but Harley appears to actually hope it will. She spends the rest of their fight explaining how messed up their relationship was, before getting whacked in the head with an axe by the escaped clown.
But even this goes in Harley's favour, as the villain realised he moved the axe at the last second to avoid beheading Quinn - making him realise that he does actually care about her. And for someone like the hateful jester, that's the worst thing that could have possibly happened.
