Top 30 Most Adult Superhero Cartoons

Top 30 Most Adult Superhero Cartoons

Welcome to WatchMojo, and today we’re looking at the most adult animated shows and movies to grace the superhero genre. As thematically mature as “Batman: The Animated Series” was, we’re limiting this list to cartoons more exclusively geared towards older viewers.

#30: “Batman: Caped Crusader” (2024-)

The latest animated “Batman” show combines the old with the new. This version of Gotham and the character designs harken back to Batman’s early days in the comics. At the helm is Bruce Timm, one of the key creative figures of “Batman: TAS.” Even if “Batman: Caped Crusader” doesn’t reach the heights of its predecessor, the TV-14 rating allows Timm to take this world to places he couldn’t always before. The results are disturbing, surprising, and dripping with a retro-gothic atmosphere. The serialized story also provides compelling arcs for Barbara Gordon, Dr. Harleen Quinzel, and - naturally - Bruce Wayne. While the show has a higher body than some of Timm’s past work, the complex characters are what make the show “adult.”

#29: “Watchmen Chapter I” (2024)

Seeing how Zack Snyder already gave us a faithful adaptation of the groundbreaking graphic novel, you wouldn’t think another would have much to offer. Of course, the medium shift from live-action to animation does provide a fresh perspective. While there was a novelty to seeing live actors play these characters, watching Dave Gibbons’s illustrations come to life one frame at a time is equally thrilling. This first half of this two-part adaptation not only captures the source material’s look, but also its hard-hitting tone. A murder mystery at its core, “Watchmen” strips away the romanticism we associate with superheroes. There are no beacons of inspiration here. It calls the very nature of masked vigilantes into question, almost making us grateful they’re largely contained to fiction.

#28: “Batman vs. Robin” (2015)

Since his conception, Robin has generally been the bright spot in the Batman Cave, appealing to a younger demographic. The Boy Wonder has gone to darker depths over the years, however. Being trained by the League of Assassins, Damian Wayne may be the angstiest Robin. In this 2015 film, Damian finds himself at odds with his biological father and his moral code. On the other side of Damian’s shoulder is the mysterious Talon, who feeds into his killer instincts. Whether or not Damian gives in, blood will be spilled as he fights his father, his new mentor, criminals, and the Court of Owls. The most intriguing conflict is the one inside Damian - torn between being a hero or an assassin. Either way, he’s nobody’s sidekick.

#27: “Harvey Birdman, Attorney at Law” (2000-07; 2018)

Boomers might recognize Birdman from his short-lived stint on Saturday mornings during the 60s. This isn’t your dad’s Harvey Birdman… or his Fred Flintstone, or his Scooby-Doo. Although Harvey’s clientele is comprised of childhood icons, they find themselves in serious legal battles concerning child custody, substance use, and organized crime. Did we mention that Harvey has left crime-fighting behind, pursuing a new career as a lawyer? Regardless, we say it counts as a superhero show, as Harvey still soars with the wings of justice… even if some of his clients aren’t exactly squeaky clean. But hey, every toon is entitled to a fair trial and legal representation! Plus, aren’t lawyers basically the superheroes of the courtroom? The defense rests!

#26: “Space Ghost Coast to Coast” (1994-2004; 2006-08)

Space Ghost ran so Harvey Birdman could fly. Well, technically Space Ghost spent most of his talk show sitting behind a desk. The point is the adult animation landscape would likely look different if not for Space Ghost, Zorak, Moltar, and a revolving door of special guests. Originally produced for Cartoon Network, “Space Ghost Coast to Coast” later became a flagship program for Adult Swim. It set a tone for many Adult Swim shows that followed with its surreal nature and irreverent humor. While there isn’t much crimefighting, being a superhero is still a big part of Space Ghost’s identity. It shows that superheroes can not only have lives beyond crimefighting, but careers as well. In Space Ghost’s case, he’s the host with the most.

#25: “Batman Beyond: Return of the Joker” (2000)

“Batman: TAS” and “Batman Beyond” struck a balance that appealed to kids and older viewers alike. With “Return of the Joker,” this continuity grew up with its younger audience, leaving childhood behind. Nowhere is this more apparent than in the horrors that Joker inflicts upon a young Tim Drake. The Joker’s fate is just as twisted, so much so that Warner Bros. initially refused to release the film in its original form. Given the recent tragedy at Columbine High School, that isn’t surprising. In time, though, the uncut version would see the light of day with a warranted PG-13 rating. Whichever version you watch, this is easily one of the darkest Batman films and depictions of the Joker (animated or live-action).

#24: “SuperMansion” (2015-19)

If you think this series looks like “Robot Chicken,” that’s because it was created by Matthew Senreich and Zeb Wells. In addition to stop-motion artistry, “SuperMansion” carries a similar comedic blend of casual dialogue, absurd situations, and bad taste that doesn’t taste half bad. The series is adult in more ways than one as team leader Titanium Rex faces his two greatest foes: old age and an evolving world. Along with his band of misfits, Titanium Rex strives to prove that there’s still a place for the League of Freedom. The series may not break new ground, but like “Robot Chicken,” the clever writing, sharp animation, and first-rate voice acting capture the essence of adults at play - putting their old toys in more mature circumstances.

#23: “Batman: The Long Halloween” Parts 1 & 2 (2021)

Ever since DC started adapting graphic novels and comic limited series into animated features, fans were eager to see “The Long Halloween” done justice. Written by Jeph Loeb with artwork from Tim Sale, “The Long Halloween” is one of the most involving Batman mysteries and arguably the definitive Two-Face story. While the source material would inspire a few live-action “Batman” movies, this two-part film is the retelling we waited years to see. This adaptation doesn’t disappoint as Batman sets out on a months-long endeavor to uncover the elusive “Holiday” killer. Batman combats other familiar foes along the way, seeing Gotham evolve from another crime-ridden city to a supervillain hub. Although the story spans several holidays, its overarching haunting tone is in the spirit of Halloween.

#22: “Kite Man: Hell Yeah!” (2024-)

Although we’re totally on board the Harley and Ivy ship, we admittedly felt a little bad for Kite Man. The good news is that Kite Man is doing just fine with his spinoff. He’s also found his true better half in Golden Glider. While their romance is surprisingly sweet, everything else concerning this show is depraved, ludicrous, and violent as hell. What’s not to love? The series essentially starts as a sitcom with superheroes as Kite Man balances his work and personal life. His desire to run a bar slowly snowballs into something more cataclysmic with world-ending stakes. As immature as the show is, there’s an emotional maturity to Kite Man and Glider’s relationship that gives it a beating heart.

#21: “X-Men ‘97” (2024-)

A sequel series that matured with its audience, “X-Men ‘97” picks up where its predecessor left off. Not just continuity-wise, but thematically. “X-Men” was never afraid to tackle serious issues like prejudice. “X-Men ‘97” is the next step in the story’s evolution. It’s harsher, heavier, and more morally challenging. As much as we want to follow Charles Xavier’s unifying example, Erik Lehnsherr’s extreme approach has rarely felt more justified. Maybe peace is beyond reach and the only way to ensure mutant survival is to speed up humanity’s extinction. “X-Men ‘97” is never black and white, though, often leaving viewers torn on who to side with. All we can agree on is that the theme song still slaps no matter how old you are.

#20: “Batman: Gotham by Gaslight” (2018)

Although the Caped Crusader has dealt with gruesome criminals before, he’s never done it quite like this. For one, this is a Victorian Era Gotham. There is also the fact that Batman isn’t chasing any of his infamous rogues. This time, he’s after Jack the Ripper himself. The memorable setup turns this gritty thriller into more of a twisted whodunit. And as with any murder mystery, the path to the culprit is littered with some very gruesome character deaths. “Gotham by Gaslight” is a coarse and violent affair that dives into the dark realities of grim detective work. While a good chunk of its cast ends up in body bags, it’s still a bloody good time.

#19: “Marvel's M.O.D.O.K.” (2021)

A show centered on a supervillain in suburbia practically writes itself. When that villain is also an incompetent, oversized head, you get “Marvel’s M.O.D.O.K.” This family comedy sticks out because its mature jokes and most brutal scenes are brought to life with stop-motion animation. Oh, and did we mention that “M.O.D.O.K.” just happens to feature a few superheroes? The show revels in making fun of Marvel icons with great cameos and sharp humor. They’re put into a number of situations that might even be too violent for the MCU. Despite getting canceled way too soon, the short lived M.O.D.O.K. is a good way to see Marvel heroes in an adult light.

#18: “The Awesomes” (2013-15)

These B-list heroes aren’t famous for their powers or reputations. Truthfully, they’ll always be remembered for pushing the envelope. Not just with sex, substances, and rock and roll - though, there’s still plenty of that. “The Awesomes” goes the extra mile by proving that social commentary is best delivered through gut-busting humor. While some might call it rude,that’s part of the charm. If anything, the mish-mash of tones is the reason the explicit humor lands so well. The show definitely pushes the boundaries of good taste. But once you get to know the characters, you might just be convinced that they’re all awesome.

#17: “The Death of Superman” (2018)

In recent years, the DC Universe Animated Original Movies series has adapted iconic moments in comic book history. “The Death of Superman” stands out as one of its most faithful and brutal. After an out-of-control Doomsday lands on earth, he carves a path of destruction and death through the world. Both civilians and heroes receive harsh and fatal injuries. At one point, Cyborg is nearly completely ripped apart. The film also beautifully fleshes out Superman’s life before he races into his rough battle with Doomsday. Epic in scale, emotionally-driven and tackling mature themes, “The Death of Superman” is everything a longtime fan needs.

#16: “Injustice” (2021)

Near the beginning of a movie, a grief-stricken Superman kills the Joker. And the events only get darker from there. It’s not just the sheer brutality of the characters that makes “Injustice” hard to stomach. What makes this movie so hard to endure is that Clark’s actions cause a civil war between once friendly heroes. Their ideological arguments eventually turn into shouting matches, fist-fights, and even deaths. None of them are merciful, either. No, they’re the “let me know when I can look again” type of death scenes. The “Injustice” movie amps up the ruthlessness of its source material to give us a shocking superhero civil war.

#15: “Hit-Monkey” (2021-)

In this case, the title pretty much tells you all you need to know. It follows a monkey… who’s also a hitman. Oh, and he’s mentored by the ghost of a dead assassin. Bloodshed, mania, and crassness ensue. “Hit-Monkey” is definitely a lot to take in. And yet, there’s just something undeniably thrilling about it, too. Maybe it’s the thoroughly unique premise. Or perhaps we like the way Hit-Monkey gets his paws bloody in just about every episode. Either way, this is totally a show worth going bananas over. Just brace yourself for the messy side of Hit-Monkey’s day job.

#14: “Batman: Year One” (2011)

Based on the critically acclaimed run of Batman #404 to 407, this film explores Batman’s early crime-fighting career and the foundation of his unique relationship with James Gordon. As with most of Frank Miller’s comic book work, Year One was notably dark and mature in its themes. The film definitely respects the source material in this regard. In addition to showing the more mature side of Gotham, the realistic injuries will make you wince. There’s also coarse language, adult professions, and scenes that are definitely not appropriate for kids. Batman’s first year out is undoubtedly a grown-up affair.

#13: “Hellboy: Blood and Iron” (2007)

Released between “Hellboy” and “Hellboy II: The Golden Army”, “Blood and Iron” featured voice work by the live-action film cast. Ron Perlman, Selma Blair, Doug Jones and John Hurt all returned for this grim story. In this follow-up, the storytelling is tighter, the tone darker, the threats all the more frightening. It doesn’t shy away from the horrifying world established throughout the “Hellboy” mythos. There are legitimately scary scenes that would frighten people of any age. At the same time, the movie never loses sight of its complex plot or intriguing character relationships. This mature animated film definitely lives up to its source material.

#12: “Suicide Squad: Hell To Pay” (2018)

“Hell To Pay” doesn’t spend a lot of time convincing you that the villains sent on a deadly mission are secretly good or have redeeming qualities. That’s mainly because its characters are far too busy assassinating rivals, avoiding death and using their skills in fatal ways. Every person in this motley crew of villains is capable of excessive violence. And true to the title, a good number of the squad members are killed off before the credits roll. Since this movie is every bit as dark as it is funny, it’s a joy to watch. It’s a great companion piece to other adult suicide squad tales like “Batman: Assault on Arkham”.

#11: “Justice League: The Flashpoint Paradox” (2013)

In this alternate timeline, Wonder Woman and Aquaman are at war, Bruce Wayne isn’t Batman, and Superman is a hollow shell of his former self. And yet, even against all of that, the most harrowing part of “The Flashpoint Paradox” is Barry Allen’s story. His desire to save his mom’s life created a reality where people are trapped in a hell on earth. Thankfully, the grim tone never distracts from the film’s empowering message of acceptance. It doesn’t let Barry outrun his grief. Instead, “The Flashpoint Paradox” tackles it with respect and sophistication. The movie’s strong morals turned an already-great and mature film into an absolute must-watch.

#10: “Justice League Dark: Apokolips War” (2020)

Did you ever wonder what would happen if the Justice League couldn’t stop a major villain? Well, “Apokolips War” has got you covered. This movie boasts one of the highest body counts of any DC movie to date. Most of the Justice League is either killed, captured or twisted beyond recognition. The Green Lantern Corp? Doused in magma. Oh, but surely The Teen Titans make it, right? Nope, not even they are spared from the war. Yeah, “grim” doesn’t even begin to cover it. “Apokolips War” is the bleakest of the bleak, and easily one of the most grueling films in DC’s catalog. After all, it’s saying something when the so-called “happy ending” consists of resetting the entire timeline.

#9: “Stripperella” (2003-04)

The late, great Stan Lee made innumerable contributions to the world of comic books. This creation, however… was his gift to his adult fans. Rated TV-MA, “Striperella” was an overtly adult series following a superhero/stripper by name of Erotica Jones. She was voiced by none other than Pamela Anderson. The series only lasted one season and turned away many potential viewers based on its very racy premise alone. However, it was more than a gimmick. “Stripperella” offered genuine laughs, clever moments and yes… plenty of adult appeal. It truly is an animated superhero offering that you’ll have to get an eyeful of to believe.

#8: “Batman: Under the Red Hood” (2010)

Within the first few minutes of this movie, Robin is physically tormented by the Joker, a building explodes, and Batman holds the body of his deceased sidekick. This opening sequence sets the tone for one of the darkest caped crusader stories ever. Batman’s failure to save his last Robin comes back to haunt him when the Red Hood goes on a violent tear through Gotham. Blood is shed, villains are savagely beaten, and heads literally roll. The film expertly uses its violent scenes to make a commentary on the audience’s tolerance for brutality. Through the tragedy of Robin and the Red Hood, we’re forced to question if Gotham can only be saved if villains die.

#7: “The Maxx” (1995)

Before “The Maxx” came along, people had never really seen a superhero cartoon like it. Come to think of it, even two decades after its release most people still haven’t seen anything like it. This one-of-a-kind series remains a gruesome and underappreciated cult classic of the MTV generation. “The Maxx” follows a homeless man who is also a mighty warrior in the surreal landscape known as the Outback. The animation is ever-changing, the tone absurdly dark and the subject matter is heavy. One villain commits such despicable acts that we can’t even say them here! While the series may be too dark and heavy for some, it’s undeniably brilliant.

#6: “Constantine: City of Demons” (2018)

Given the name, it shouldn’t come as a shock that this is less of a superhero flick and more of a full-blown horror film. While Constantine has always concerned himself with the occult, his stories haven’t always given us this much gory insight into his life. The movie is really not for kids...or honestly, anyone with weak stomachs, either. From the demon executions to a particularly steamy scene in a bar bathroom, the movie doesn’t hold back. Longtime Constantine fans will gravitate to the story because he and his dark world aren't watered down a bit. The devilishly entertaining and grim narrative truly reflects the dark nature of his stories.

#5: “The Boys Presents: Diabolical” (2022)

Thanks to the power of animation, this bloody spin off actually manages to be more violent and gruesome than the live-action series. Each episode of “Diabolical” has more expletives, more gore, and more insane twists than the last. An early career Homelander-centered story especially pushes the limits of gore. Since it’s an anthology series, “Diabolical” has license to blow up its premise after each episode - sometimes, literally. Once the credits roll, it all resets for yet another round of unhinged bloodshed. But it isn’t all just blood and guts. The show is full of tons of topical commentary about society and the superhero genre. As a result, “Diabolical” is the red-soaked gift that keeps on giving.

#4: “Batman: The Dark Knight Returns” Parts 1 & 2 (2012-13)

Released in two parts, the first in 2012 and the second the following year, “The Dark Knight Returns” is an adaptation of one of the most famous Batman stories ever published. A miniseries written by Frank Miller in 1986, “The Dark Knight Returns” explores an alternate future in which an aging Batman comes out of retirement and ultimately faces off against Superman. This story is about flawed heroes existing in a world made up entirely of moral gray areas. The violence on display is extreme, the language is strong, and vices are around every corner. It’s one of the best animated Batman films ever made. But wait until the young Bat-fans are older teens to share it with them.

#3: “Harley Quinn” (2019-)

Harley Quinn took her signature bat and smashed everyone’s expectations into smithereens with this series. Following Harley Quinn’s life after she steps out of the Joker’s shadow, this show is one of the most vulgar animated programs out there. Civilians die by the truckloads throughout the series. Since characters have no filters, expect lots of strong language and adult jokes. Fans will also get an eyeful because the show does not shy away from adult activities. Amidst all of the chaos, the show also manages to be surprisingly heartwarming. It’s all pulled together by the fantastic Kaley Cuoco, who spouts off Harley’s lines with incomparable comedic timing. This funny, crude and honest show never once apologizes for what it is.

#2: “Invincible” (2021-)

A teenager learning to balance heroics and everyday life sounds like fun for the whole family, right? Wrong. By the end of the very first episode, “Invincible” lays its cards on the table - and it’s 100% not PG. As it turns out, Mark’s growth into the titular hero is also peppered with bursts of gratuitous, red-stained combat. The series isn’t shy about showing it off either. Still, it’s not quite right to call “Invincible” “gritty.” It’s more akin to a fantastically-realized coming-of-age tale. Just one that has more than its fair share of bloody death matches. “Invincible” isn’t always an easy watch, but trust us, it’s definitely worth it.

#1: “Todd McFarlane's Spawn” (1997-1999)

From the same mind that gave us the iconic Spider-Man villain, Venom, the Image Comics character Spawn isn’t fit for young fans of any age, be it in comics, films or this animated series. Airing on HBO, “Todd McFarlane’s Spawn” debuted in 1997 and ran for three short seasons. Today, it is remembered as one of the greatest superhero shows ever produced. And in 1999, it even won an Emmy. The series follows a man betrayed and killed by a friend, only to return to earth as an agent of hell. His gruesome adventures were explicitly adult-only, and featured everything from sex to severed limbs. The series was often grotesque, but was also excellent.
