(Author Note: this a bit AU if Princess Mandie came after Mark in Timmy teen years and I might change the rating if I thought of a good chapter anyway enjoy this story,)
On a warm summer night in Dimmesdale sixteen-year-old Timmy Turner is walking back home after coming from the movie theater watching the latest Crash Nubla movie with his friend Aj. Timmy wore a pink hoodie, white shirt, blue jeans, white socks, black converse, and same old pink hat; Timmy still has his famous size buck teeth when he was a kid. Timmy even got his godparents Cosmo and Wanda they were are off on their wedding anniversary on a fairy cruise ship for a few days, and his parents went to pencil convection in Las Vegas that his dad was dying to see and his mom wasn't too thrilled about as he was. For Timmy, he had the whole for the two weeks since he too old for a babysitter, so his parents didn't hire Vicky to much of Timmy delight.
"This is great two weeks alone at my house sucks that Wanda and Cosmo went on that cruise ship but good for them. As for me, I'll kick back on the couch with no worries in the world," Timmy thought he happily whistled as he walks back home.
Up in space, a Yugopotamia spaceship race toward earth in full speed inside of the ship is Mark Chang freaking out and running around the ship.
"That hideous woman is going to find me at any minute I gotta get to earth mightiest warrior to help me," said Mark
Mark flies his ship into earth atmosphere than a long blue and white ship flies past mars and fellow mark ship to earth.
Back on Earth Timmy made to his house as he unlocks the front door Mark shipped lands on Timmy front yard, Mark comes out of the ship screaming his head off and coming up to Timmy.
"Timmy you got to help me out!" shouted Mark
Timmy put his hand over Mark's mouth and shush him "shut up Mark you're going to wake the whole neighborhood up, and they'll see an alien spaceship parked on my front lawn with a green alien screaming," Timmy removes his hand from Mark's mouth.
"But I'm in danger, and I need your help and your fairies,"
"Cosmo and Wanda are on their wedding anniversary they won't be back in a couple of days, but I can still help so what wrong?"
"An ugly beast is after me,"
"What did you do Mark?"
"I didn't do anything it's my stupid parent's fault,"
Timmy see a couple of the neighbor's house lights turn on "how about you tell me about it somewhere more safe to talk,"
"Okay, I got the perfect place,"
Timmy and Mark enter Mark ship as they fly out of Timmy front lawn and they fly to the city dump Mark, and Timmy get out of the vessels Timmy plugged his nose from the dump smell, and Mark breathes it in.
"What a beautiful place," said Mark
"Yeah, it's gorgeous now tell me what made you come to earth Mark?"
"My parents force me to be a marriage with an ugly girl that goes by the name Princess Mandie see for yourself," Mark pulls out a hologram of Princess Mandie.
Timmy jaw hit the floor "are you kidding me, Mark, she is smoking hot,"
"No, she isn't Timmy she is disgusting looking, and my true love is Vicky she is so rad I wanted to go out with her instead of marrying Princess Mandie,"
"Whatever floats your boat dude,"
"Timmy you got to hide me from her at all cost,"
"Why don't you just make yourself a disguise from your Fake-i-fier?"
"Your brilliant Timmy,"
Timmy pulled out his phone search a random image of a guy and found a picture "what about this," Timmy shows Mark an image of an early twenties long blonde hair guy wearing a green striped shirt, khaki pants, and brown sandals.
"Hm I'll give a try," Mark used his Fake-i-fier to turn into the image that Timmy showed him Mark looked at his new body "this body feels weird Timmy,"
"Don't worry you'll get used to it,"
Then the blue and white shipped arrive in eath and float over the dump that Timmy and Mark are standing in.
Mark looked scared "oh no she here,"
"Mark just relax you're in a disguise she won't recognize you,"
Princess Mandie comes down from her the ship in from a beam and lands in front of Timmy and Mark she pulls out a flaming sword.
"Alright, humans did you see a Yugopotamia around in this dump of a planet," said Princess Mandie
"No, we haven't right buddy," Timmy elbowed Mark's arm.
Mark felt petrified as Mandie stares him down in a panic he grabs Timmy and throws him down to the ground next to Mandie and points at him.
"He's the Yugopotamia your looking for!" Mark shouted
"What!" Timmy say in shock
"It's true why would any human have those size teeth of his,"
"You're right human nice try Mark in your ridiculous disguise of a bucktooth human teen," said Princess Mandie she grabs the back collar of Timmy shirt
"Wait I'm not Mark that blonde guy is I'm human," Timmy pleads to Princess Mandie.
"Shut up Mark," Princess Mandie speaks into a wrist device "beam us up," the ships beam up Timmy and Princess Mandie.
"Mark I'm going kick your sorry ass for this you asshole!" Timmy shouted out of angry
Timmy and Mandie get into the ship, and the ship flies out of earth Mark looked joyful with Princess Manide gone.
"I'm sure Timmy can handle himself, and that he won't stay too mad, he is a great guy for helping me," Mark thought.
