SMG3's Gang, also known as the Anti-Cast, the Dark Force, or the Snitchy Squad, is a group formed by SMG3, the evil counterpart of the SMG4's Gang to kill SMG4 for ruining his career, The group consists of resurrected villains from previous bloopers, and later doppelganger counterparts of the SMG4 cast. The gang serves as the main antagonistic faction of the blooper Super Mario 64 Bloopers: smg3's plan to destory smg4 cause he felt like it as well as The YouTube Arc.
SMG3 reappears and attempts to get Bowser to join his clan but Bowser disagrees and ends up being knocked off a ledge.
SMG3 was going to steal the Super Sacred Orb of Power from a shop but it was sold out. SMG3 returns to Bowser's lair and uses the damaged Nightmare Stone to resurrect many villains of the past including: X, Silent Guy, Bot, Robot Clone, Crazy Toilet Dude, Xboxfan996, John Gayham, The Monster, and Asian. Back at the castle, Xboxfan997/X senses that the villains are back and starts to spaz out on the floor, sensing doom. Mario and Toad notice this and Mario regards it as normal for X.
Back in Bowser's lair, SMG3 reveals that he resurrected the villains so he could destroy SMG4 and Mario. John Gayham suggests attacking the castle, but SMG3 refuses because it isn't cool enough. Asian suggests shoving cookies up Mario's *** and Bowser suggests having a picnic outside his lair. SMG3 refuses because his evil plan is the best. He gathers the villains and finds Bot crushing on the Nightmare Stone.
SMG3 and the villains plan to secure a death ray, which is under tight security. When one of the guards try to help, SMG3 shoots him. Silent Guy uses a bomb to blow up the security, allowing them access to the death ray. Once the death ray is operative, they use it to create a black hole in the sky.
SMG3 projects himself onto the window of Peach's Castle and tells how he created the black hole to destroy them. The heroes go with FM to find help.
SMG3 and the villains grow bored in the black void. SMG3 shows off his "death cannon", which is actually just a bullet bill launcher. Xboxfan996 gives SMG3 a nuke to fire out of it and a countdown activates.
Mario and friends see Bowser and he helps them defeat SMG3 because SMG3 called him fat. He hides them in a box and gives it to SMG3, leading him to believe its a box of cookies as an apology for not joining his evil scheme. Mario and friends jump out of the box to attack. SMG4, X, and FM are captured shortly after. SMG3 takes Mario to his stolen battle arena and they duel after Mario trips. Even though SMG3 is winning the fight, Mario won't die so SMG3 pulls out his death cannon with the nuke inside which he will use to blow up Mario. When the cannon gets jammed the two stare at each other for several minutes, waiting for the cannon to fire. When it does fire it blows Mario and SMG3 up and destroys the black hole.
Bowser, the villains, and the caged heroes see this and Bowser offers to take everyone out for burgers. To which everyone happily cheers.
SMG3 starts a audition for a play that loosely reenacts the episodes, SMG4: If Mario Was In... Splatoon 2, SMG4: Mario Gets His PINGAS Stuck In The Door, and the story arcs of the SMG4's series, while being disguised as a Cromulon from Rick and Morty. He has chosen the actors who are trying to get a role in the play, including Mario, Belle Fontiere, JubJub Boopkins, Rob the Scarecrow, Whimpu, a Luigi Doll, and a watermelon wearing Meggy's headgear, who had gotten the roles. After the play, the SMG4 cast realized the reenactments wasn't a original play and it turns out to be a production of Snitch Productions, and SMG4 ran off to find SMG3, who he knew had written the play.
After when both groups of SMG4 and SMG3 escalated into a fight. Mario then was able to stop the bickering between the two content creators, and led to a truce between two factions (although SMG3 still had a grudge). The two factions finally came to an end, calling for peace with each other, and both went their own ways.
