Alrightie here's the crossover I've talked about.
It was another day at the Loud House, Lincoln was reading his comics in the living room while his sisters were doing their own things (Lori and Leni talking with each other, Luna playing her guitar, Luan watching her show, Lynn listening to Lucy's Poems, Lola and Lana jumping rope, and Lily playing with blocks when Lisa came down the stairs.
"There you are, I want to show you my latest invention." She said.
"Another invention?" Lynn Sr. asked as he and Rita came to the living room.
"Let's hope it's useful for once." Rita said.
The Family came to Lisa and Lily's Room, there was a watch on her desk.
"I give you the teleportation watch, it can send to anywhere across the world" Lisa introduced.
"You mean anywhere? Like France or maybe Mexico?" Asked Lori
"Correct Eldest Sister." Lisa grabbed the watch. "Any volunteers?"
"Me me me!" Everyone raised their hands. But Lisa had her eyes on Lincoln.
"Lincoln."
"Yes" He raised with a fist in the air.
"Awwwwww. I want to go see a dumpster in Hazeltucky" moaned Lana.
Lincoln grabbed the watch and put it on.
"Now type in where you want to go." said Lisa.
Lincoln typed in Dairyland and pressed the button and with a star of green light he vanished. After a couple minutes, a star with green light appeared and Lincoln came back with a Dairyland Hat on his head and an ice cream cone.
"Whoa that is so cool!" Lynn exclaimed.
"I know right?" Lincoln said as he licked his ice cream cone accidently spilling some on the watch.
"Careful, that Lincoln, the watch is sensitive to a dairy products." Lisa warned.
"I'm sure it be fine." Lincoln claimed. but much to his shock, the watch started to spark and fitz.
"Is it supposed to do that?" asked Leni.
"Stand back everyone!" Yelled Lisa.
Lincoln looked at the watch, the name Saga suddenly popped up on the screen. "Saga?! Where's that!?" Lincoln asked before being teleported away. The rest of the family were stunned by what just happened.
"Don't worry everyone, I'm sure Lil bro will be teleported back here in a few minutes." Said Luna slightly worried.
It was all calm and easy in The Franchouchou mansion. The Zombie Idols and their manager, Korato were talking about their last concert at the living room. Sakura, Saki and Ai were sitting on the couch while Junko, Yugiri and Lily were behind with Tae biting on Junko's head.
"Did you see your fans cheering for us?" Sakura said.
"Yeah, we totally hit it there!" Cheered Saki.
"I Agree." said Ai. "We should keep moving forward. Let's rehearse."
Just then a white-haired boy with an orange shirt suddenly appeared in the living room. The group were surprised to see how a human got into their mansion.
Lincoln looked around and saw that he was in a mansion of some sort.
"So this is Saga, wonder why I'm in this ro-"
The boy looked up and to what the group hoped to avoid was shocked to see zombies in front of him.
"Z-z-z-zombies! Ahhh!"
"This isn't good, that kid just saw that we're zombies! what are we going to do?!" asked Junko panicly.
The boy then looked at them again, they didn't seem to be hostile like the zombies in his VG gaming glasses or in the movies, in fact they seem to act just like any other person (aside from the one with the long black hair.)
"Don't worry, we had this before with Maimai, we just have to explain everything to him." said Sakura
"And just how are we suppose to do that seeing how he reacted to us?" Asked Lily
Lincoln then noticed something else, he looked at his hands and noticed that he looked like an anime character.
"Whoa when did I become an anime boy?" he asked. He then turned to the girls knowing that he could trust talking to them he asked them a question. "Excuse me, why am I an anime boy?"
The zombie idols looked at each other.
"What are you talking about?" asked Ai.
"I'm guessing this is normal to you." he said with shrug. "According to my watch, I'm in Saga right?"
"Yep, that's right, but ummmm...What watch?" Asked Saki.
Lincoln looked at his arm and noticed that the watch was gone. "Aahhh! Where is it!?"
"You mean this watch?" Sakura said as she held the watch up unbeknownst to her, Tae pressed one of the buttons. "Tae! You can't mess with other people's-" but before she could finish the Egghead Idol disappeared in a green star of light, much to the others' surprise.
"WHAT DID YOU DO?!" Yelled Korato.
"What happened to Lady Sakura?!" Wailed Yugiri.
"I don't know, your friend pressed that button that would sent her back to-" Just then Lincoln realized where the watch send Sakura. "Uh-Oh."
The Loud Family were still waiting for Lincoln to teleport back.
"Poo poo" asked Lily
"Just give it a few more minutes Lily." answered Leni.
"Wherever Lincoln's at, I'm hope I have a better flower to where. Hahahahaha Get it?"
Just before the family could groan at Luan's joke a green star of light appeared.
"About time." said Lola.
But the person to be teleported back wasn't Lincoln, but a pinked haired zombie girl with a school uniform and a spotted bow.
"I-is that a-a" said Leni in a shuttered tone.
"Zombie? Cool." said Lucy.
Sakura looked around. She was in a green colored room with lab equipment along with baby stuff. To make matters worse she there were a bunch of humans who saw her without her makeup.
"Oh no. What do I do?! What do I do?!" ask the zombie.
The family noticed that she wasn't hostile, in fact she seems to be Inteligent.
Lori was the first to Speak to the zombie.
"Uhmmm excuse me but who are you?"
Sakura turned around as she fidgets her fingers in her thoughts. "I'm not supposed to tell my real name to anybody but since they now know I'm a zombie I suppose there's no point in keeping it a sec-"
Just then Sakura noticed that her hands were cartoony, she looked at the rest of her body and noticed she was a western cartoon!
"W-Why am I a western cartoon?" She asked.
"What are you talking about?" Asked Luna
"Nevermind that, Where's Lincoln?" Asked Lynn.
"Lincoln? You mean that white haired boy with an orange shirt?" Asked Sakura.
"Yep that's him." answered Lana.
"Well, he suddenly appeared in my mansion and then one of my friends touched his watch and now I'm here."
"Speaking of which do you happen to have said watch in your possession?" Asked Lisa
Sakura gave Lisa the watch. The second youngest sibling looked at the damage.
"Just as I thought it seems that this will take some time for me to fix."
"Wait, Lincoln said that watch took him to someplace called Saga. Is that where you're from?" asked Lola.
"Um...yeah" answered the Pinked haired Idol.
"Where's that?" asked Leni.
"It's in Kyushu, Japan" answered Sakura.
"You know for a zombie, you actually look pretty Cuteshu." Luan joked "Hahahahahahahahaha Get it?"
The others except Lynn Sr. groaned.
Lily then walked up to her.
"You Zowbae?" She asked.
Sakura sighed. "Yes I am. Watch." She grabbed her head and pulled it off her body which surprised the others. She then reattached her head.
"Awesome." Said Lucy
"I can't believe it, a zombie who can talk and act just like a normal person." Said Lynn Sr.
"Guess you can't really believe everything you see on TV." replied Rita.
Meanwhile back in the Frachouchou Mansion, the gang were talking about what just happened.
"First a human suddenly teleported into our mansion, and now Sakura's gone missing. As if this day can't get any crazier." Lamented Saki.
"If I had to guess, I'm pretty sure she was sent to The Loud House in Royal Woods." Said Lincoln.
"Is that where you're from?" Asked Junko.
"Yep, It's a small town in Michigan."
"Michigan? As in the State in America?" asked Ai
"That's right"
Tae then walked up to Lincoln "Whaoughyargnamuhhh?" she asked.
Meanwhile in the Loud House. "You name?" Asked Lily
"Oh, my name?" Both Lincoln and Sakura said simultaneously, "It's Lincoln Loud/Sakura Minamoto!"
And there you have it! I decided to go with the Jimmy Timmy Power Hour approach by have the characters be in the artstyle when they enter each other's worlds. Please let me know what you think of the fanfic in the comments below! and Be sure to check out my other crossover too! Later!
