From pretty bad to the just plain horrifying, here are the most toxic relationships ranked with the DCEU, aka the DC Extended Universe. Based on the superheroes and super-villains from the DC Universe, these live-action and animated films have captured the effects of being in an unhealthy relationship. Superheroes aren't known for their stability as they come in and out of relationships. Super-villains don't even care in the slightest how they are treating their significant partners. You're better off being on your own if you ever do decide to take a risk and give your heart to someone else.
When putting on a cape and covering your face with a mask, like Batman does every night, don't expect Bruce Wayne to suddenly show up on time and open up about his feelings. Even with someone as loyal as Superman, Clark Kent is always under constant danger from a menacing enemy. Even Wonder Woman was warned by her mother, Queen Hippolyta, that she should stay away from men, but she didn't really listen to her wise advice. Towards the end of a toxic relationship, someone is always getting hurt and their heart comes out broken.
10 Batman and Catwoman
When Bruce Wayne and Selina Kyle are in costume, they bring out the worst in each other and call it flirting. In The Dark Knight Returns, Selina (Anne Hathaway) sets up the caped crusader for a trap and directly leads him to the super-terrorist known as Bane (Tom Hardy).
The cat burglar doesn't even bother sticking around to help when Bane breaks the Batman's back. In Batman Returns, when the unmasked pair discover each other's secret identities, Selina (Michelle Pfeiffer) automatically assumes they are going to start fighting again.
9 Steve Trevor And Wonder Woman
Notice how Steve Trevor (Chris Pine) acts like he wants Diana (Gal Gadot) in the battlefield. When he's with the boys, including Sameer (Said Taghmaui) and The Chief (Eugene Brave Rock), Steve shows a different side of himself. Trevor doesn't actually believe anything that Diana honestly told him, especially that she's a goddess and the daughter of Zeus.
Even though Steve and Diana have been intimate with each other, he's hiding secrets behind her back and pokes fun of her origin story. Anything she tells him, he just doubts her at every turn.
8 Batman And Rachel Dawson
Though they were childhood best friends. Bruce Wayne (Christian Bale) almost put Rachel Dawson (Katie Holmes) in trouble when he secretly carried a gun with him in Batman Begins. Rachel actually had to knock some sense into him and slap him around after he reluctantly handed the loaded weapon over to her.
And then in The Dark Knight, Bruce wants to steal Rachel away from her true love, Harvey Dent (Aaron Eckhart). Out of pure jealousy, Bruce promises to give up the cape and cowl to win Rachel back, but he knows she is actually with a better and honest man.
7 Enchantress And Rick Flagg
Even though he's putting millions of innocent lives in danger, Rick Flagg (Joel Kinnaman) doesn't reveal the love of his life, June Moon (Cara Delevingne), has been taken over by her other personality, Enchantress. In Suicide Squad, Rick will do anything to save June's life even though Enchantress has complete control of her mind and body.
With Enchantress reigning down hell of earth, Flagg is willing to lie to his superior, Amanda Waller (Viola Davis), and risks the lives of Task Force X. Lying ate every turn, Rick thinks sacrificing his teammates will make everything okay.
6 Mera And King Orm
In Aquaman, Mera (Amber Heard) is quite manipulative when she is around King Orm (Patrick Wilson). Even though they are engaged and she is meant to be his queen, Mera is doing everything in her power to dethrone Orm. Mera just pretends to be romantically involved, even though she secretly hates everything that Orm stands for.
King Orm wants to conquer the world outside the waters and dominates over Mera in order to make himself feel superior. If their marriage was ever to take place, it would definitely be a loveless one.
5 Mera And Aquaman
Mera manipulated a reluctant Arthur Curry (Jason Momoa) to fight in a gladiator match against his own brother. Arthur and Orm hadn't even met before but Mera orchestrated events so that the two siblings had to duke it out for the throne. Even though Arthur is charmed by her beauty, Mera constantly mocks him everywhere they go.
Mera is endlessly surprised whenever he shows a hint of intelligence, especially when Arthur recites his knowledge of Italian history. Engaged to someone else, Mera is cheating on Orm with his own brother.
4 Green Lantern And Carol Ferris
Even though Blake Lively and Ryan Reynolds are married in real life, none of that chemistry between them appeared on screen during the Green Lantern movie. Carol Ferris (Lively) has feelings for an ace test pilot, Hal Jordan (Reynolds), but he's afraid to commit.
Even though their feelings are mutual, Hal sleeps around with other women. Hal then blames his responsibilities as a Green Lantern will keep him away in outer-space, making him unable to concentrate on their relationship. Hal is just using that excuse to escape from a serious relationship.
3 John Constantine And Zatanna
In the comics, John Constantine, the private investigator of the dark arts, has been known to drown himself in alcohol to deal with his inner demons. In the animated Justice League Dark, audiences learn Constantine was in a previous relationship with magician Zatanna Zatara.
Their breakup was so devastating to the former couple because Constantine and Zatanna refused to speak with each other afterward. Still stinging from their breakup, Zatanna was not very pleased to see Constantine again. Even though they were not on good speaking terms, he reluctantly had to ask for her help to save the world.
2 Harley Quinn And Nightwing
In the animated Batman and Harley Quinn, Pamela Isley aka Poison Ivy has been stirring up big trouble now that she teamed up with the Floronic Man. Reluctant at first, Batman believes the only other person who can help them is the Joker's ex, Harley Quinn.
Refusing to let her say no, Dick Grayson, also known as Nightwing, stalks after Harley until she changes her mind. Nightwing doesn't even bother listening to Harley as she says she just wants to live a normal life. After sleeping together, Nightwing avoids Harley as if she is a one-night stand.
1 The Joker And Harley Quinn
In Suicide Squad, the Joker (Jared Leto) plays mind-games with Harley Quinn (Margot Robbie) before she ends up diving into a vat of chemicals. The Joker just wants her to be completely obedient to him, with no questions asked.
Nothing Joker actually does to Harley is ever wrong, even when he starts acting like her pimp. Joker actually wants to sell Harley to a rival gangster, Monster T (Common). Always faithful to her man, Harley shows her undying loyalty as she attacks Batman (Ben Affleck) for ruining their date night.
