Young Sheldon 10

By: DoctorEd17

Chapter 1: And then there was 10

...

Earth 1989…

We go to a forest in Texas under the moonlight where we see an 9 year old boy running down a path. He has brown hair and blue eyes. He is wearing brown pants, a blue t-shirt and shoes.

His name is Sheldon Cooper and he was running away from a butterfly. At least until he noticed the butterfly was gone.

"Phew!" Sheldon said

He then noticed a green glow coming not too far from Sheldon's position. Because of his scientific curiosity. He decided to investigate the glow.

Sheldon walked over to the glow and noticed it came from…

"A watch?" Sheldon asked

We see it was a watch except the there's a green hourglass symbol where the clock should be. The rim of the dial is white and has four green arrows, and the area behind the hourglass is now the same color as the new wristband: medium stone grey. The outer band is black with green arrows, and the sides of the dial and the ends of the wristband are silver. The top of the grey wristband has a green hourglass underneath the dial.

Sheldon then reached for the watch to look at it when all of a sudden we see the watch jump up and attached itself to his left wrist.

"(Screams!)" Sheldon said as he tried to pull the watch off but it was like pulling on his own skin

After a while, Sheldon's scientific curiousity finally got to him as he realize that the device could not be a bomb.

He looked at the watch and noticed the triangle button. He pressed it and the core popped up and the hourglass symbol became diamond shaped. In the middle of the diamond was a silhouette of a humanoid creature are whose head is flame shaped.

"Interesting..." Sheldon said

He then turned the dial and the Silhouette changed to some sort of cat guy.

"Curious..." Sheldon said before turing the dial again

We see what looks like a humanoid frog Silhouette.

Sheldon then slowly and dramaticaly pushed down the core. Once the core reached the bottom we see a flash of green light surround Sheldon...

(We see Sheldon's skin turn gray as he shrunk down. At the same time we see his eyes turn yellow...)

When the flash of green light was gone, we see a Four inch tall humanoid frog. He has Yellow eyes with rectangle pupils and gray skin. He is wearing a green jumpsuit with a black stripe down the middle. A white hourglass symbol is on his back.

He looked at his hands and said, "Holy butter briskets!"

"I'm guessing that the device I am or was wearing is some sort of a DNA altering device. Capible of combining my DNA with the Genetic material of the life form I am now." Sheldon said

Sheldon's eyes widened as he realized something.

"Whoa! The life form I have become must've increased my intelligence tenfold!" Sheldon said

We then hear a branch break as George and Georgie arrived at Sheldon's location.

"Sheldon!" Georgie yelled

"Where could he be? He couldn't gotten too far..." George said

"I'm down here!" Sheldon yelled

The two Coopers looked down at and saw the frog creature.

"What the Hell?" George asked

"Looks cool. Can I keep it?" Georgie asks

"Yeah... you don't want me." Sheldon said

"OK... What the Hell are you?" George asks

"Your names are George and Georgie Cooper." Sheldon said

We then hear a beeping sound from the hourglass symbol as it flashed red.

We then see a flash of red light and once it faded we see Sheldon is human again.

"I can explain..." Sheldon said

...

We go back to the Cooper campsite where Sheldon just finished explaining his story.

"So that watch jumped up and clamped onto your wrist?" George asks

"Yeah. When I was that creature I was 10 times smarter then normal!" Sheldon said

"That frog made you more smart?" Georgie asks

"Yeah." Sheldon said

We then see an explosion not too far from the campsite.

"What the?" George asked

...

We go to a bunch of campsites where we see a giant red and orange robot terrorizing said campsite.

We go to a bush where we see the Cooper boys looking through.

"Is that..." Georgie asks

"A Giant robot!" Sheldon whispers

"First that watch, Now a Giant robot?" Georgie asks

"Dollars to Doughnuts it's after the watch..." George said

"And I doubt it is a friendly..." Sheldon said

"We better get out of here." George said

We see George and Georgie leave but Sheldon kept looking at the campsite. Then he looked at the watch before making his decision.

He activated the watch and started to select a creature.

George and Georgie noticed and George asked, "Sheldon?"

"With great Power comes great responsibility... If I have great power, then I need to use it responsibly." Sheldon said before pushing down the core

(We see Sheldon's DNA Altered as Orange fur grew all over his body.)

After the flash of green light we see a humanoid tiger alien. He has one claw sticking out of each wrist. He has green eyes and black and white eyebrows. The white hourglass symbol is on his chest.

"Clear a path for the Rath!" Sheldon yelled before running on all fours towards the robot

"Sheldon..." George yelled

We go to the robot where we see it pointing its laser at a family when...

"Hey Robot!" a Voice yelled

We see the robot turn to see Sheldon standing behind it.

"Let me tell ya something, Giant Robot... When you threaten a family. You threaten Rath and you should NEVER THREATEN RATH!" "Rath" yelled

Rath then launched himself towards the robot. The robot pointed its laser at him only for Rath to upper cut the laser with his clawed arm as a result laser was fired into the sky.

We see Rath claw the robots chest open and pulled out a bunch of wiring which made the robot stumble around as it malfunctioned. Then Rath pulled out another wire and the robot fell down as it deactivated.

"And stay down!" Rath said

Rath then noticed the family look at him before the little girl said, "That... was... cool!"

"Thank you." the man said

"No problem... That is what heroes do..." Rath said before walking into the woods

...

We go to the Cooper campsite where we see Rath just arrived before changing back to Sheldon.

We see George and Georgie wall over to Sheldon and George said, "Were you crazy?! You could've died! If you're going to be a superhero, you're going to need training."

"Say what?" Georgie and Sheldon asked

"I was proud of you. You could've used it for personal gain, but you used it for good." George said

"What about Mom?" Sheldon asks

"I think that we should keep it a secret from her for right now." Georgie said

"Agreed. If I am to be a superhero, We'll need complete secrecy. If people were to find out you guys and everyone I know would be in terrible danger." Sheldon said

"So no telling Mom, Missy or Meemaw. OK Georgie? " George said, "Or anyone else..."

"Okay... sure. I'm interested in that watch anyway..." Georgie said

...

The Next day...

...

We see the Cooper boys packing up for their trip back home.

After doing his share of the packing, Sheldon activated the watch and started turning the dial.

Georgie notices and asks, "Whatcha doing?"

"Counting the Aliens on this device." Sheldon answered

"Aliens?" George asked

"The Robot and the creatures I turned into last night are obviously not native to this world. They were either sent by God or Extraterrestrial..." Sheldon explained

"Sheldon, I don't think God would send a Giant robot to terrorize a camp site." George said

"Correct... So that leaves us with theroy number #2. They are from outer space." Sheldon said

"Space? As in Aliens?" Georgie asks

"Precisely..." Sheldon said as he turned off the device

"So... How many of those aliens does that thing have?" George asks

"So far... 10." Sheldon said

"10?" Georgie asks

"You would think that with a big Universe there would be more than that." George said

"You're right. But I only have access to 10 aliens right now." Sheldon said

"Maybe it's some sort of training wheel thing. You know like on those bicycles." Georgie said

"Yeah... You're probably right. Whoa. Never thought I'd say that." Sheldon said

...

We go to the car going down a road in Medford, Texas. Before the car got to the Cooper house. George said, "Remember, Keep the Watch a secret."

...

We go to the Cooper house where we see the boys enter through the front door.

"We're home!" George said

We then see Mary, Missy and Connie (AKA Meemaw) run to the Cooper boys and hug them in relief.

"Thank the lord you are Okay." Mary said as she hugged Sheldon, then Georgie then George

"What do you mean?" Georgie asks

"You're kidding. It's all over the News!" Connie said

She then pulled out a Newspaper and showed them the front page...

"ROBOT ATTACKS CAMPGROUND..."

"Last night a Giant Robot attacked a campground. Thanks to the actions of some sort of Mutant Tiger named Rath. Rath destroyed the robot before anyone got hurt...!"

There was also a picture of Rath fighting said robot.

"Wasn't that the campground you three went to?" Mary asked

"We saw the fight while we were hiding in the bushes..." Georgie said

"A big talking cat destroys a giant robot. How in the heveans name is that possible?" Mary asks

"I kind of like Rath... He's cute and can fight. That would make a good doll." Missy said

"Anyway mom I had a good time. Mostly because of what I witnessed last night." Sheldon said

"Good to hear Shelly." Mary said as she hugged Sheldon again

...

Here it is my 1st Young Sheldon and Ben 10 (Classic and Reboot) crossover. Hoped you liked it...

NEXT... George takes Sheldon to an abandoned factory so that Sheldon can learn his new powers.

If the Characters seem a little OOC. Then forgive me...
