10 Worst Things The Joker Has Ever Done To Harley Quinn
3. He Turned Her Into A Constellation
The Joker is one of the most formidable villains in the world despite not having any powers, so just imagine how bad things would be if he was a god.
In the Superman storyline Emperor Joker, the interdimensional imp Mister Mxyzptlk decided to grant the Joker 1% of his power. However, the Harlequin of Hate tricked him and ended up with 99% of Mxyzptlk's power instead.
Joker used his near-omnipotence to create a twisted version of the world, one where Bizarro led the Justice League and Superman was locked in Arkham Asylum for murdering Lex Luthor.
His crimes didn't stop there though and he also used his powers to finally kill Batman. He then resurrected the Dark Knight and began constantly killing him and bringing him back. He later grew bored of that though and moved on to bigger things like eating the entirety of China.
Eventually he was stopped, but towards the end of his reign, he committed one last act of villainy. As a "reward" for all of Harley's years of service, he killed her and transformed her into a constellation. In his words, she was getting "the best seat in the house".
