Following the traditions of other comic book crossovers, IDW Publishing utilized their recently licensed classic Cartoon Network properties by gathering together the characters from their best shows into a 6 issue mini-series Crisis Crossover. Shows included are Samurai Jack, Ed, Edd n Eddy, Dexter's Laboratory, The Powerpuff Girls, and Ben 10: Omniverse.
The story concerns Jacks archenemy Aku gathering together Vilgax, Mojo Jojo and Mandark from their respective worlds to form a League of Extraordinary Villains in an attempt to conquer the Multiverse. Together they then proceed to build a large army of robot mechas to invade their own worlds, capture their rivals, and bring them back to their space station (Ed, Edd, and Eddy are taken by mistake). The heroes are then forced to team up with each other in order to thwart the villains plans and return to their own worlds.
Beginning in June 2014, Super Secret Crisis War spanned 6 issues, written by Louise Simonson, with the addition of 6 one-shots. The one-shots will concern other Cartoon Network worlds the villains try to invade, and included two page back stories to the main comics. They include Johnny Bravo, Foster's Home for Imaginary Friends, The Grim Adventures of Billy & Mandy, Cow and Chicken, and Codename: Kids Next Door.
Not to be confused with CN's other, similar crossover, Cartoon Network: Punch Time Explosion.
Tropes for the main Story Arc include:
- Action Survivor: Writer Louise Simonson has stated the Eds' status as being this, since they're the only characters out of the group that don't possess any special abilities (other than Cartoon Physics).
- Badass Normal: Even though the Eds are still the weakest protagonists overall, they still manage to defeat one giant robot on their own using ingenuity.
- Chronic Backstabbing Disorder: Gee, do you think four villains working together would be willing to share their spoils?
- Crossover: A comic crossover between Samurai Jack, Dexter's Laboratory, The Powerpuff Girls, Ben 10: Omniverse, and Ed, Edd n Eddy, with the one-shots including Johnny Bravo, Cow and Chicken, Codename: Kids Next Door, The Grim Adventures of Billy & Mandy, and Foster's Home for Imaginary Friends.
- Crisis Crossover: The heroes have to work together to stop the villains from destroying their worlds.
- The Last of These Is Not Like the Others: Ben and Ed, Edd, and Eddy fulfill these tropes in different ways; Ben is the only protagonist whose show was still airing new episodes at the time, and was never a part of the Cartoon Cartoon Fridays block while Ed, Edd, and Eddy are the only protagonists without any combat abilities.
- MacGyvering: Dexter's means of offense is building guns out of destroyed robot parts, and he occasionally trades up for better guns as soon as they start destroying better robots.
- Morality Chain: Mandark is prevented from being truly evil because he's thinking of Dee Dee.
- Nice Job Fixing It, Villain!: Aku and Vilgax mistakenly sending Dynamo into the Eds' world when their robot mooks spill their drinks on the control panel. Though they are not seen as a threat, they eventually play an important part in bringing down their plans.
- Mojo Jojo's HeelFace Turn was partly motivated by how the other villains didn't take him seriously. Aku points out that he had expected Mandark to betray the villains first, since he had tricked him into almost destroying his own world.
- Aku and Vilgax both blame each other for this during their fight in the climax. Vilgax blames Aku for his over-zealous antics, while Aku points out how he complained so much.
- Robot Me: The cover of Issue #3 shows off evil robot duplicates of all the main heroes, minus the Eds. The Villains intended to use these duplicates to conquer more worlds.
- Magitek: All of Aku's robots and his space station function as this. Each robot is powered by an Oni Spirit.
- This Looks Like a Job for Aquaman: The only reason Dexter was able to build any devices after being captured was the Eds' knack for savaging parts.
- Shared Universe: Averted. Each show is split up into its own dimensions, as opposed to Cartoon Network's usual Cross Through.
- Shout-Out: The title is one to various crossover events of comic history, such as Crisis on Infinite Earths and Secret Wars (1984).
- Spanner in the Works: The Eds, and Mojo Jojo after his HeelFace Turn.
Aku: Not the super powered Heroes that are the templates for our army, but we might as well conquer their world, too.Vilgax: Judging by their level of technology, it should take about five minutes.
- The villains are quick to point out how the Eds are not much of a threat as heroes.
- Story-Breaker Team-Up: It's established that Mojo Jojo and Mandark both feel outclassed by Aku and Vilgax, and it plays a major role in the story.
- Villain Team-Up: In usual crossover tradition, the conflict is caused by the alliance of four Cartoon Network villains: Aku, Vilgax, Mandark, and Mojo Jojo.
- You Have Outlived Your Usefulness: As the Johnny Bravo one-shot shows, Aku is planning to kill his comrades once they've served their purpose. Later one-shots show that the other villains plan to do this as well.
Tropes for the One-Shot Stories include:
- Deal with the Devil: Chicken nearly signs a contract with Red Guy to get rid of one of Aku's robots in the Cow and Chicken one-shot, only for said robot (who short-circuited from getting wet with coffee) to attack after its systems came back online.Red Guy: Seriously?! You couldn't wait 5 more seconds?!
- Lawyer-Friendly Cameo: The "Life Coach" that Grim hires to get rid of the invasion robot bears a passing resemblance to Dr. Lawrence Jacoby from the 1990s Drama Twin Peaks.
- Precision F-Strike: On the Cow and Chicken one-shot, Chicken says a swear.Chicken: ...Damn...Red Guy: You Rang?
- Unsound Effect: Twice on the Cow and Chicken one-shot: "CWUSHING EMBWACE OF FWIENDSHIP" and "SIBWING WOVE" at the end.
