Brock came into Kali's room and saw a message.

"Dear Adventure Kids, we have Kali. If you want her back, come find us. P.S., Bring the cosmic buddies."

"I can't read." Brock says.

Albert soon saw the message in Brock's hands.

"Oh, no, this is not good. Your sister was taken." Albert says.

"What do we do?" Brock asked.

"We save her!" Ann says.

"How?" Brock asked.

"Oliver." Cynthia says.

"What can he do?" Brock asked.

"He has magic, remember?" Cynthia says "You'll help, right, Oliver?"

Oliver nods. "Of course I will." Oliver says.

"Let's do this! We don't have to do anything. Luke and Oliver's got this." Cynthia says as they go to rescue Kali.

Kali was tied up.

"Where am I?" Kali thought as she was in a cell with some rotting corpses. She shrieked, beginning to freak out.

"Brock, Ann, Cynthia?! Anyone?!" She cried, beginning to feel scared.

One of them looks at her.

"Ru..." he coughed before crawling to her. Kali shook. This was all kinds of wrong.

One of their organs was scattered as Kali felt sick to her stomach.

Another kid lost his eyes and an arm. One was burnt and there was even a dead baby.

Meanwhile

"Wait, we've never met the Golden Shooter. I think we're lost." Brock saye

"He didn't even leave a map." Ann realized.

Luke knew exactly where to find him as he had taken him on before, so he led the way.

"So you're on Angry Luigi's hero team?" Brock asked. Luke shook his head, explaining he took on the Golden Shooter without them at least a few times.

"That's weird. According to research. He's a bounty hunter, why hunt Luke?" Teeders asked

"Cause I'm good at basically anything." Luke says.

Meanwhile, Angry Luigi and Savannah arrived at Mike's house with Emma and gasped seeing Jane. Abby came downstairs and froze.

"What's going on?" Emma asked.

"Look, I can't take you back there, Abby." Mike says

Emma glared

"Mike, please, you can't..." Savannah says as Abby ran to her room, angry. Emma goes to check on her

"I'm staying to make sure they're okay." Angry Luigi says.

"Good idea." Savannah says as she goes with Mike.

Mike texted the Adventure Kids, needing help

"Okay, Brock and I will save our sister. You guys go find Mike." Ann says.

Later, Brock and Ann arrive with Luke and Oliver and see the Golden Shooter, who was holding Kali hostage.

"Give our sister back!" Brock and Ann shouted. A cage fell on them.

"Shoot!" Brock says.

"It seems Luke and Oliver came instead." the Golden Shooter says, annoyed.

"What do you want with them?" Luke asked, his eyes in angry slits.

"Nothing, honestly, the cosmic buddies were supposed to come. Not you." The Golden Shooter says.

"Well, too bad." Oliver says.

"But you're captured" the Golden Shooter says as a red blur rushed and grabbed Kali and landed. Nightbite landed next to the turtles as they had Kali.

"Kali, are you all right?" Mikey asked.

"I guess..." she groaned.

"Okay, let's send him to the scrapyard!" Leo says.

"Wait, don't destroy all of him." Donnie says as Raphael leaped up with his sai and dove down. The Golden Shooter teleported as Raphael blinked. The Golden Shooter reappeared.

"Raph!" Leo says as he tries cutting the Golden Shooter, who flew up, shooting missiles as the turtles dodged. There were explosions.

Donnie was figuring out how to open the cage as Nightbite tries to punch the Golden Shooter, who shot lasers at her.

Nightbite dodged, using her insane reflexes.

The Golden Shooter shot lasers as Nightbite leaped up and rushed towards it.

Donnie finally frees Luke and Oliver.

"Done!" Donnie says.

"Brock! Ann!" Kali says, hugging them.

The Golden Shooter teleported behind Nightbite and shot a laser at her as she dodged, but was starting to get tired as they moved around at high speeds. The turtles were having a hard time keeping up

Nightbite kicked the Golden Shooter who punched her as he shot a laser blasting her down badly

Luke transforms into Elemental Equalizer and glared as the Golden Shooter shot lasers at him

Elemental Equalizer dodged and tried shooting flames, but the golden shooter teleported and tossed gooey bombs. Elemental Equalizer dodges them all and soon finds the main system and short-circuits the Golden Shooter using a powerful water attack.

"That was easy." Kali says.

"Okay, let's go already..." Raphael says, walking off.

"You know he has anger issues like you, Luke." Leo says and walks off.

Nightbite got up. Thankfully, she was okay.

Meanwhile, Teeders and David arrived at the diner.

"Wait, where are the others?" Mike asked as he was there with Remy, Stephen, Lonnie, Savannah, Bill, and Colleen.

"Busy, they will be here." David says.

Meanwhile, Cynthia was keeping an eye on Jane, not trusting her in the slightest.

With Bill, he watched the cameras and noticed Chica at the door and closed it "Okay, what was that for?" Bill asked.

"I don't know, wake up Mike." Bill says as Teeders sees the sleeping pills

"Great...we're on our own." David says as Cecilia takes out knives.

"We'll have to fight our way out." she says as Teeders sees Bonnie and froze and closes the vents.

"We're doomed!" Teeders says.

"I'm sure they're friendly..." Savannah says as Foxy came in, cut Savannah's arm, and sent her flying.

"Oh, shoot!" Bill says as Foxy cuts Mike a couple of times. Bill tossed a lasso at Foxy. Foxy tried fighting out of it as Mike woke up.

"Holy..." he says.

"We should go." Bill says as they hurry out of the room and head for the door, which was locked.

Foxy was in the hallway as Cecilia walked up, being the bravest.

"Bring it on!" Cecilia says to Foxy. The lights went out as Foxy jumpscared the screen.

Meanwhile, Angry Luigi was looking for food when he turned around and saw a golden Freddy and looked nervous.

It glares at Angry Luigi, who took out a hammer and leaped towards it, trying to hammer Golden Freddy, who punched Angry Luigi in the face. Angry Luigi was on the ground.

"Hey, what's going on?" Jane asked as Golden Freddy tries to grab her, but Angry Luigi bounced off him and landed on his feet as Golden Freddy slapped him across the room. Angry Luigi crashed through a table.

Emma and Abby came down.

"Freddy!" They say, excited, but then see Jane. Golden Freddy knocked her out.

"Eh, no one will miss her." Emma says as Cynthia peeked over the stairs, seeing this as she gulped. She didn't want to follow them. She didn't have the strength to beat Golden Freddy and Angry Luigi was hurt.

Meanwhile, Cecilia woke up as she and the others were strapped to chairs.

"Where are we?!" David asked.

"Teeders, Bill, any bright ideas, you nerds?!" Cecilia asked, scared.

"The bolts!" They say as Bill's mini drones took it out as they barely escaped in the nick of time.

Meanwhile Angry Luigi and Cynthia ran outside, seeing the taxi drive off.

"We need to get them back!" Cynthia says "And since Oliver is busy, it's up to us!" she says

Mike and his gang were in their vehicle, smirking. Angry Luigi shrieked and ran off as he ran back and grabbed Cynthia and ran again, leaving dust in his wake as Mike flew after him.

"I'm starting to wish Luke was here!" Cynthia says as Angry Luigi runs behind a house and hits his Omnitrix, turning into Slapback and looking annoyed.

"Okay, not what I planned, but here goes nothing, hit my back!" Slapback says as Cynthia slapped it as Slapback split into 2.

"Clones? Neat! Looks like we can handle ourselves. I forget you have powers. Not as strong as Luke or Oliver, but enough." Cynthia says as Mike shot boxing gloves, but the Slapbacks counter by punching them away. They charge towards Mike, who drove into them as the Slapbacks hold it back.

Meanwhile, Vanessa found the others.

"You!" Bill says, holding his blaster. "You're behind this, aren't you?"

"No!" She says as the door was kicked down. It was Kali and the others.

"It wasn't her." Kali says.

Meanwhile, Angry Luigi and Cynthia hide in a room.

"Okay, Steve Reagan, we know you're behind this!" Cynthia says.

There was a recording.

"Steve? Well, not exactly, You're the only ones to question me, but you two should have come with Luke." the recording says.

Suddenly, the Golden Shooter came out as Angry Luigi and Cynthia froze and awaited their doom. However, a pipe rose up as Mario came out and saw this.

"Huh?" Mario asked

"Wait, is that the Mario?!" Cynthia asked.

"Mario, distract this guy. I need to save my sister." Angry Luigi says.

"Okay, let's-a go!" Mario says and leaped towards the Golden Shooter. As they began fighting Cynthia began to wonder, is Steve his real name?

Angry Luigi and Cynthia jumped in a pipe.

They arrive in a toilet as Alem tuber came out of the shower, cracking his knuckles

"Bro, someone took Emma!" Angry Luigi says. Alem tuber got dressed and growled.

He grabbed Cynthia and Angry Luigi and flew.

"My father is behind this and his name is William Afton" she says.

Raphael put a Sai near her. "You could have told us earlier!" He says.

"Yeah!" Teeders says

"And now they want Abby!" Mike growled.

"Well, we're the Adventure Kids and we're ending this." Kali says as her body emitted a small glow.

"Whoa!" Everyone says.

"David, you and Oliver will stop fighting or you're going to regret it!" she says.

"Yes ma'am!" they say, hugging in fright.

They arrive at the diner as Alem tuber flew in and tossed Angry Luigi as he fell, but Cecilia rushed and caught Cynthia and hugged her before actually crying.

"You're okay!" She sobbed as Cynthia smiled and hugged Cecilia like never before as everyone just let this moment play out. Cecilia was never like this.

"Cynthia, I love you, sis..." Cecilia sniffed.

"I love you, too. Hey, we're going to get through this. No one messes with my sister!" Cynthia said.

"Okay, who are you?" Alem tuber asked the Adventure Kids and turtles.

"Oh, you've never met the rest of my friends." Kali says

"No time to lose!" Alem tuber and Angry Luigi said as they were eager to save Emma.

"Go, Cosmic Machine!" The cosmic buddies says

"It's adventure time!" The Adventure Kids say.

"Twin power!" The twins say.

"More like annoying power..." Raphael says.

"Come on!" Leonardo drags Raph along.

Later, Mike and the Adventure Kids snuck through the vents. But they only saw Bonnie and Freddy on stage performing. Kali gave some hand signals, sending some of the others a different direction so they could get to the cameras in the office to search for the rest of the animatronics and be the gang's extra pair of eyes.

Mike, Kali, Teeders, and the turtles opened the vent and snuck up towards the stage before Freddy had the chance to see them. The big animatronic bear looked around a bit before he resumed singing.

"Let's turn these robots into a pile of scrap!" Raph whispered.

Mike then noticed some buckets of water and poured them out on the stage while Freddy and Bonnie remained unaware of him. Kali then nodded to Teeders and she nodded back, showing that she had a taser.

Teeders shot the taser right at the animatronics' feet, causing them to go haywire and fall to the ground. Freddy and Bonnie fell down.

"Now, let's find Chica and Foxy." Leonardo told the team.

Just then, everyone heard some familiar screams.

"Abby!" Mike cried.

"They're in the back room!" Cynthia told them through their radios as she was watching through the cameras in the office with the others.

"Hurry!" David added.

Meanwhile, Chica grabbed Emma, who put bubble gum in her mouth and was about to use her powers, but realized Chica was probably being controlled

Suddenly, Angry Luigi and Alem tuber stomp on Chica and kick her aside.

"Brothers!" Emma sobbed and hugged her brothers as they smiled and hugged back. Mike hugged Abby, grateful she's alive.

"Okay, let's blow this joint!" Oliver says.

Angry Luigi grabbed Emma, running the wrong way. Cupcake started chasing Angry Luigi, but Mikey used his nunchucks to knock Cupcake back. Cupcake leaped towards Mikey.

"Wait, wait!" Mikey shouts as Cupcake attacks Mike's leg. Abby is nervous.

"Abby, go!" Leo says and kicks Cupcake.

"Head for the exit through the dining room." David instructed them through their radios.

"But be careful." Cynthia warned. "We don't have eyes on Foxy."

"Guys, go with them" Kali told the rest of the Akids to go with Abby to protect her.

Angry Luigi skids to a stop seeing Golden Freddy.

"What is that?" Emma asked.

"New plan, go to the dining room. I'll handle this." Alem tuber says and rushes towards Golden Freddy, who punches Alem tuber, knocking him back. Angry Luigi took out an ice flower and shot ice balls as Golden Freddy powered through it. Ice Angry Luigi and Alem tuber attacked with a barrage of punches and kicks.

Meanwhile, Luigi was running as Mario and Fire Daisy stomped on The Golden Shooter, finally putting it down for now.

"Okay, let's see what this is about." Daisy says and reads some letters in a secret box after melting the lock.

"Oh, my God, this guy is a murderer! Mario we gotta stop him!" Daisy says.

"Luigi, let's-a go!" Mario says as Luigi was shaking in fear. Mario grabbed his brother and dragged him as Daisy chuckled.

Meanwhile, Foxy was on the hunt as Emma and Abby hid behind one of the machines.

"Nobody make a sound." Ann whispered, being on the other side of them with Brock and Teeders.

They nod as Emma was about to sneeze, but Abby saved her.

Foxy got closer and looked at the machine to see no one. Emma, Abby, Brock, Ann, and Teeders were in the ball pit

Freddy and Bonnie were slowly getting up and were about to move until Mario came in with Luigi.

Freddy tries to attack Mario. "Yippee!" Mario says, leaping on his head and stomping on him, which to his surprise, did nothing.

"Oh, no..." Luigi says as Bonnie walked towards him.

"Mario!" Luigi says, freaking out.

"Luigi!" Mario says as he took out a green shell and kicked it to Bonnie. Bonnie just looked annoyed as Mario did a slide kick, tripping Bonnie as Freddy approached Mario, who leaped over him. Luigi used his green bullet, knocking him back, but held his head.

Foxy was walking towards the ball pit as Emma was shaking, scared.

Meanwhile, Alem tuber growled, annoyed as he started punching Golden Freddy and kicked him, sending him flying as the Golden Shooter arrived for one last round.

"Oh, great..." Alem tuber says as it flies towards him.

"Hey, bro, find Emma and leave. I'll kill these guys." Alem tuber says as he got trapped in a gooey bubble.

"Crud!" Alem tuber says.

The Golden Shooter turned around seeing Angry Luigi, who gulped and sighed as he unleashed a dark aura, unleashing Bruty and shot a bunch of power fists at The Golden Shooter, sending him flying.

The Golden Shooter shot lasers as Bruty was sent flying.

"Hey, Chica, pizza time!" Mikey says, using Chica's love for pizza to gain an advantage.

"I'll deal with Foxy!" Raphael says and runs.

Emma and Abby felt someone getting closer as Emma got ready, but it was just Vanessa who pulled them out.

"Vanessa!" Emma says as Foxy turned, only for a sai to hit his eye as Raph smirked. He leaped and punched Foxy as Freddy walked towards Mario, but Leonardo slashed him with his sword, knocking him back.

"Mama-mia!" Mario says

"Great, a plumber just so happened to get dragged into this..." Leo says.

Mike and Kali were coming in, but to everyone's horror, a big bunny rabbit suit came out.

"Um, dudes, who is that?" Mikey asked.

"I think that's the one behind all this." Leo says.

Mike tries using a taser, but it didn't work.

"I got this." Raph says, but Springtrap knocks Raph into Mike.

"You couldn't just leave it alone, could you?" Springtrap says as Kali's body glowed a bit.

He then noticed Leo and Donnie charging so he grabbed them and slammed them into each other.

"Pathetic!" He says. "This is perfect. Children, wake up."

Bruty glared at Springtrap and unleashed Insanity, who smirked and tried punching him, but it seemed the suit had defense as Springtrap fought back.

He punched Insanity into Kali

Kali tries punching him but he grabbed her and tossed her outside as Insanity tries attacking again but sensed something.

"Asyaurd!" Insanity says as Springtrap shot a blast sending Insanity back as he reverted to Bruty, who tries holding it as he was outside, then he reverted to Angry Luigi as there was a huge explosion.

Kali and Angry Luigi were floating as they unleash dark auras and use their new powers.

"Thanks to my new friend I can kill more kids! There is nothing you can do to stop me!" Springtrap says

Angry Luigi and Kali look down and cross him as the screen shows a flurry of punches as Springtrap was sent flying.

"How is he getting powers?" Mike asked.

"Asyuard?" Bill asked

William took off the mask and was rushing for the others. Vanessa got in the way as he stabbed her.

Mario took out a metal cap


Mario smiled as metal climbed across his body as Metal Mario punched his fists


metal Mario punched him but the metal broke

Mario froze as Springtrap tries to finish him but Peach leaped and saved him

Donnie hits him with his bo as Mikey used his nunchucks to hit him. Raph punched him and Leo tries cutting him, but he knocked the turtles away and shot lasers to the others as Oliver used a magic forcefield blocking the attack

Kali unleashed insanity as Angry Luigi was confused not sure how Insanity got into Kali

Insanity flashed and punched William, sending him up and shooting a barrage of punches.

"Whoa!" The rest of the kids say.

Angry Luigi took out a cape feather and unleashed a yellow aura before crossing his arms as he had red electricity. He rushed and hit Willam with a spin jump.

Raccoon Mario and Raccoon Luigi flew in and stomp on Willam damaging him best they could.

Nightbite and Luke punched him down.

The power-ups wore off as Kali fell down as this was too much on her body

"You brats!" He says.

"Freddy, Bonnie, Foxy, Chica, are you going to let him get away with this?" Emma says as she and Abby show them a drawing.

Freddy and the others glare at Springtrap.

"What are you doing?! Don't you think of turning your back on me!" William says as Freddy gives Mario a nod. Mario nodded as Mike and Abby carried Vanessa out of there. As Freddy and his friends attack Willam

Kali vomited out a white ball as her body was back to normal. Her friends hugged her

Angry Luigi eats it as his powers was back.

"I guess the powers were only temporary." Bill says as they had taken Vanessa to the hospital.

"We should be heading back." Peach says

"Yeah!" Mario says.

"Hey, I know you didn't want to be a part of this adventure, but thanks, Cosmic buddies." Kali says

" Oh yeah thank you so much!" Mario says.

"Any time." Angry Luigi says as the Cosmic buddies, Mario, Luigi, Peach, and Daisy wave. They all go in the pipe as it closes.

Luke sighed and walked away. Today wasn't a normal day where he saved lives.

"Hey, Luke, thanks." Kali says.

"We did it! We saved the day!" Ann says. Cynthia kissed Oliver's cheek as Oliver howled. Then she kissed David so he couldn't complain

"What now?" Brock asked.

The next day, the Adventure Kids were in line to get tickets for Luke's concert. Oliver just smiled as he walked up to them.

"You guys don't need tickets. Because Luke personally gave you front row center seats." Oliver says with a smile. "And backstage passes!"

"Sweet!" Ann squeals.

Luke sat in his dressing room and sadly stared at his table calendar as he combed his hair.

In a week, it would be his birthday and he knew his siblings would forget. And he knew his friends would forget, too. His feelings began to turn bitter as he got ready.

He soon came on stage as Ann squealed. Luke had to smile for the sake of his many fans.

He soon performed with his band as the fans screamed with delight. And when the band broke into their rendition of "Jingle Bell Rock" as this was a holiday concert, Ann screamed as they sang.

Kali smiled. After that adventure, she needed a break

Meanwhile, in the Mushroom Kingdom, Toadsworth looked up to see the heroes arriving.

"Princess!" He says with joy.

"Yep, we're back." Peach says As the skies turn dark.

Bowser was seen on his ship, laughing. The Koopalings were there, too.

"Showtime!" Bowser says.

"Well, some things never change..." Savannah says. Mario and Luigi smiled as Angry Luigi got ready as they leap for the screen with Bil and Savannah as Delta and Chrissy grin.

Bowser raised his fists as bullet bills flew towards they heroes as they bounce off the bullet bills as Emma finally unleashed an acid bubble gum ball that she had been holding up as it caused a big explosion melting the airship as Bowser and his kids was sent blasting off. Everyone laughed.

At the concert, Luke and his band had finished and went backstage. Luke isolated himself as he sat alone in his dressing room.

He had been involved in an adventure and now waited.

The Adventure Kids came. "Hey, Luke, you did great." Brock says.

"Too bad we have to go back home." Ann says and hugged Luke.

"Thanks for everything. If you need us, give us a call." Kali says as the Adventure Kids prepare to head home after this big achievement.

Luke sighed and waved as Ann left him a present. Kali's crystal glowed as the Adventure Kids arrived home.

"Home at last." Cynthia says.

Luke also headed home, his head hung low.

The Louds held him as they were really worried.

Luke opened a gift, seeing a drawing of the Adventure Kids and Luke.

"Awww, you made some friends." Leni says.

He took the drawing and went to bed. He wanted to cry himself to sleep.

"What's wrong?" Lori asked. Luke just lays down, frowning, knowing his birthday will be overlooked, like always.

"We can't help if you won't tell us..." Luna says. Luke cried as he started talking.

"Overlooking my birthday in favor of your concerts and things!" Luke screamed and looked away.

"Dude, we're going to be there for your birthday next week..." Luna says.

"Yeah, right...you're just saying that so you'll leave me alone at home like you did last year!" Luke shouted.

"Eh, we've only known each other for at least 3 months." Lola says as the siblings hug him. "We won't forget."

The end

I'm not sure if this is canon or not, considering the events that happened, but hey, this was one fun ride.

"It's not canon." Cynthia says. A shark mask comes up as she runs off screen. Alem tuber laughed as Oliver kicked him off screen.

The credits show an image of Angry Luigi in the diner as Mario and Freddy play Sugar Rush.

The next image shows Cecilia and Cynthia relaxing together for once with the others

A 3rd image shows the siblings watching Leni plan for Luke's birthday.

The final image shows the Cosmic buddies, Adventure Kids, Mario, Luigi, Bowser, Luke, Oliver, Remy, Stephen, the turtles, Mike, Abby and Freddy on a stage.

Thank you for reading!

The screen closes in on Mario, who winked.

"See you next time!" Mario says as the curtains close on them.


The end

A/N: This was a big crossover. Teaming up with AdventureGirl5 and Crumbelina to write this was fun.
