Saturday Mornin Mayhem is a freeware game developed from the
M.U.G.E.N engine by Derrick D. Rowell, better known as DDR Creations. Taking inspiration from Capcom's fighting games,
Looney Tunes and
Saturday-Morning Cartoon, the story's premise consist of how a clone of Saint Nick known as Saint Not! with the help of his computer creator Big Baby put heroes against other heroes by kidnapping their most prized treasures and blackmailing them to destroy other heroes with the mindset of crushing the remaining lone hero so he can obtain the love of the children and the world.
This game provides examples of the following tropes:
- The Atoner: Elmer's plot is about wanting to revive the wabbit that he killed in What's Opera, Doc?
- Sho Nuff becomes one in his ending, realizing the true masterhood he seeked after defeating Destroyous
- The Bad Guy Wins: In his ending, Marvin obtains back his explosive space modulator and accidentally destroys the moon in the process.
- Destroyous ending consists of going to betray his master for good after defeating every hero on the earth.
- Bad Santa: Saint Not! is an evil clone of the original Saint Nick designed by his DNA
- Brought Down to Badass: An intended example performed by Zeus by taking a potion to turn himself into a powerful mortal in order to defeat Opera Elmer and stop his havok.
- Chubby Chaser: Fat Albert's stage theme, "Large and Way N Charge," is a song describing the singer's love for someone's fatness and gluttony. It's not clear whether Albert himself is singing the song or the subject of it.
- Downer Ending: In the first years, if you downloaded some characters separately you will surely get one after clearing an Arcade mode in a Standard M.U.G.E.N system.
- Popeye is betrayed by his own nephew Sweet Pea who finishes him with a powerful energy ball
- Sweet Polly and Captain Caveman Jr are still being taken hostage by their kidnappers, with the heroes being unable to defeat their powerful kidnappers.
- For Marvin, getting a fake explosive modulator, damaging his cannon, and being teased by Opera Elmer. However, this is a good ending for the earth heroes, as neither the moon or the planet are destroyed.
- The Dragon: Is implied Saint Not! is the dragon of the computer, Big Baby
- Destroyous is this for Saint Not! himself
- Elmer becomes Destroyous' dragon after the robot promises he will revive his wabbit.
- Final Boss: Destroyous is the final fighter you fight in the story mode of the game.
- Fireballs: Momasusta attacks often involve those.
- Hated by All: Saint Not!. The children despise him and refuse his toys, all the heroes want to defeat him and even his robot Destroyous attempts to revel against him for its own gain.
- Heel–Face Turn: At the end of his individual story, Sho Nuff develops one as he feels a nice power inside him after defeating Destroyous and reaching his goal of becoming the master
- Honor Before Reason: Many heroes who fight other heroes so they can save their relatives
- I Have Your Wife: Played straight with Underdog, Captain Caveman, and Popeye, as their most precious relatives are kidnapped.
- I Just Want to Be Loved: Saint Not! laments in his intro that the children don't like him and his evil toys.
- Insane Troll Logic: The plan of Saint Not! of killing all the heroes so he can be the only "hero" for the children in the world is certainly one.
- Karma Houdini: As long as the sequel or his character aren't made, Saint Not! will remain as one of these
- Killer Robot: Destroyous qualifies, as he has been created to eradicate heroes.
- Nonstandard Character Design: All of the fighters, except Peter Griffin, have their sprites drawn by DDR himself, which possess a distinctively cartoony black line artstyle, while Peter was sprited by a different creator (Warner) and thus lacks the black lines everyone else has.
- Original Generation: Momasutsa, Fly Flea and Destroyous in the playable roster, as well as the non-playable Saint Not! and Big Baby. Momasutsa serves as the mascot for the game and for DDR's emergent "Dark Street Heroes" clothing brand.
- Papa Wolf: This is mainly Popeye's and Captain Caveman's reasons to fight everyone in the cast so they can save Sweet Pea and Captain Caveman Jr.
- Playing with Fire:
- Momasusta has a lot of fiery moves.
- Popeye can summon fire from his pipe
- Plot Hole: Opera Elmer has several in his story mode and gameplay.
- Despite claiming that he killed Bugs Bunny, some wabbit marks can be found in one of his battle intro animations and announces constantly that he will kill the wabbit in his attacks, a taunt and on one of his victory animations.
- There's no explanation of why he betrayed Destroyous for Zeus is in his ending, which it only can be after he loses a battle with Zeus.
- Sequel Hook: Numerous character endings have these, as they still haven't defeated Saint Not!
- Set Right What Once Went Wrong: Duck Dodgers's main reason to fight is to traveling thought time so he can save the moon of being destroyed by Marvin the Martian
- Shock and Awe: Opera Elmer, Duck Dodgers, and Zeus both use lighting on their attacks.
- Summon Magic: Mickey mouse can summon magic mushrooms as an attack.
- 10-Minute Retirement: Momasusta retires after years of fighting crime but she goes back into action after she realizes Saint Not! is a threat to her children.
- Turned Against Their Masters: At the beginning of his introduction Destroyous thinks of doing this to his master Saint Not! after defeating the last hero on earth.
- The Unfought: As much as he is involved in everyone's stories, Saint Not! doesn't fight in the game. Only time will tell if we ever see him fight.
- Voluntary Shapeshifting: Sorcerer Mickey can transform himself into a fairy, a bee, a dragon, a tree, a ballerina hippo, or a jumping mushroom in one of his specials.
- A Winner Is You: If you download the characters separately, you will get one of those in their respective endings.
- Also played straight with Fly Flea, as his character doesn't have a story defined.
- Wounded Gazelle Gambit: Peter can pretend to have his knee hurt in one of his specials and surprise his foe with a sneak quick attack.
