Wonder Woman is slain by none other than Harley Quinn, who manages to defeat the Amazonian warrior in the sickest and most disturbing manner possible.
1 WONDER WOMAN: Winner
In the end, it is painfully clear that Wonder Woman takes home the crown, leaving Harley Quinn in a puddle of her own tears. In fact, one might be so bold as to argue that Diana wouldn't receive a single scratch during their battle.
Ra's al Ghul is one of the most dangerous immortals in the DC Universe and while he and Wonder Woman have rarely crossed paths, he was able to take her down the one time she faced him and his forces on her own.
She was able to knock down men twice her size and flip onto a moving vehicle with little effort. Harley is also strong enough to break human bones. Harley was also able to easily run while holding a thirty-four-pound bag of dog food under one arm and was later able to easily hoist it into the air with one hand.
Harley isn't picky in her affections. She likes both heroes and villains, men and women. Wonder Woman happens to be one of the most attractive superheroes, and Harley, of course, noticed. She considered herself Diana's fan and when she learned the Amazon princess was in danger, she went to her apartment to protect her.
Harley Quinn's Biggest Fear is Poison Ivy and The Joker.
Powers, abilities, and equipment
Following her transition to the main DC canon in 1999, Harley Quinn was established as having immunity to toxins and enhanced strength, agility, durability, and reflexes, which she received after having been injected a serum concocted by Poison Ivy.
She was a highly-skilled psychiatrist during her time working at Arkham Asylum, having been trained in the field of psychoanalysis, and is stated to have a genius-level IQ.
Superman has finally been beaten by none other than Harley Quinn. A misadventure across time and space sees the antihero do the impossible and actually take out the Man of Steel in a surprisingly dark way.
Weakness: Harley Quinn appears to be fearless, yet she doesn't have enhanced strength, speed, or metahuman powers, making her vulnerable to physical attacks from her more powerful opponents.
The current Cheetah, Barbara Ann Minerva, is a former archeologist and treasure-hunter who sold her soul to the plant-god Urtzkartaga for power and immortality, not realizing she would be bound in eternal servitude to him. She, aside from Circe and Ares, is arguably Wonder Woman's deadliest archenemy.
Cheetah is Wonder Woman's biggest rival, with the most iconic version of her, Doctor Barbara Ann Minerva, starting out as Wonder Woman's friend. However, she eventually grows to hate her after her transformation into Cheetah, because she blames Diana for not saving her.
She has no convenient weakness. She used to be rendered powerless if she was bound or shackled by a man, but that's been phased out. She would also go mad when her bracelets were removed.
On an even ground, it seems Harley has what it takes to disarm the Deadpool and, at the very least, mercilessly beat him up.
While Harley could certainly hold her own for a bit against Spidey, she would definitely come out on the losing end. Arguably Harley's biggest fighting asset is her agility, but as agile as she is Spider-Man is even more so.
Harley Quinn may be a great fighter, but she is loud and proud. Catwoman is the exact opposite and would find loopholes in Harley's haphazard fighting tactics. Her skills in the shadows would be a hard challenge for Harley Quinn and could mean her ultimate demise against the cat.
Harley is much better than she used to be, but so is the Joker. His unpredictability and willingness to do anything to win will give him an advantage she can't overcome. He'll take advantage of her trauma, brutalize her, and finish her off with one of his patented Joker toxins.
If anybody from the MCU could defeat Superman, it's Scarlet Witch. After defeating five members of the Illuminati, consisting of Professor X, Captain Marvel, Captain Carter, Mr. Fantastic, and Black Bolt, we don't want to imagine what Scarlet Witch could do to Superman.
Harley Quinn started off as a villain, but lately, she's been portrayed as a superhero and an anti-hero.
Apart from his physical abilities, Peter is an intellectually-gifted scientific teen genius and has a prodigious aptitude in the physical sciences, with a high IQ level of around 250.
William James Sidis has the World's Highest IQ. Anywhere from 250 to 300 is his IQ score, almost twice the score of Albert Einstein. At the age of eleven, William famously entered Harvard University, becoming the youngest person to enter. He also claimed to be conversant in 25 languages.
The figures are between 2 3/4 and 2 7/8 inches tall (with Harley actually being taller than the Joker for some reason).
We get to hear Harley called The Joker “puddin'” and Batman “Batsy”.
Harley Quinn started gave the Joker the nickname of Mr. J when she was still a pyschiatrist at Arkham Asylum. She also often calls him Puddin.
The Joker does not reciprocate her love and is in fact incapable of romantic emotion as he sees people only as tools to further his own plans. Harley is in denial of this fact and prefers to view him as an antihero until she eventually has to come face-to-face with his complete disregard for her.
