Disclaimer: Yup! We know!
Note: Finally some action. This is what Ben 10 is all about.
EXT: BACKYARD
There are berry bushes everywhere. A tiny, purple alien hides behind a tree. It's quivering.
GWEN
It looks harmless.
Gwen walks up to the purple alien. It sees her and shrikes. Another alien, tall and gooey, strikes at Gwen.
BEN
GWEN, WATCH OUT!
Kevin darts toward Gwen. He pushes her out of the way. He holds his hands out. The gooey monster knocks him down. Ben turns the Omnitrix. It reveals a projection of JET RAY. He turns it again. It's GOOP. Ben slams the Omnitirx. He transforms into Goop.
GOOP
It's time to fight goop with goop.
Gwen shoots two energy blasts from her hands. She knocks the alien off of Kevin. It howls. Kevin touches a rock. His body is rock solid.
GWEN
Are you okay, Kevin?
KEVIN
Never better.
Goop jumps on top of the gooey alien. It howls. Ben shape shifts into a neck choker and hops on the alien's neck. The gooey alien struggles and melts into a puddle. Goop slides off. The gooey alien moves fast. Goop stands tall. Kevin and Goop chase the puddle. Gwen tries to hit it with multiple blasts. Suddenly, a water ball slams on Kevin's head.
YOUNG FEMALE
Bull's eye!
KEVIN
Where did that come from?
Gwen points at the roof.
GWEN
Look there!
Goop and Kevin look up. A blue water alien is holding a water ball. It drops it. Gwen uses her energy to form a shield over their heads. The water hits the shield. The gooey alien charges. He knocks Goop down. Gwen wraps her energy around the gooey alien. She lifts it high in the air, spins it, and tosses it. The gooey alien hits the tree. Kevin runs to the alien. He picks it up and tosses it against the house.
KEVIN
That should clean up the his act.
The water alien throws another water ball at Kevin's head. Kevin scowls.
KEVIN
Come down here and fight me!
PURPLE ALIEN
Leave my family alone!
GOOP
Cooper?
Goop returns to his human form. Him, Kevin, and Gwen pause. The purple alien reveals itself. The gooey alien stands up tall. The water alien jumps down from the roof. She lands as a puddle. Then she pops back to her alien form.
BEN
Cooper? Is that you?
COOPER
Yeah! And this is my dad and sister.
BEN
Today is full of surprises.
GWEN
How did you turn into aliens?
COOPER
We don't know. Just last night we were human.
Then we woke up—
ANITA
Ugly.
COOPER
I think those berries made us this way. They appeared out of nowhere.
BEN
Oh, no. Julie is going to turn into an alien.
KEVIN
That's one more thing you two will have in common
Ben glares at Kevin.
MR. BARTON
This Julie doesn't have much time. Come with us. We can chat more at the house
Mr. Barton slides open the glass door. The aliens crawl and slid inside the house. Kevin and Gwen follow them. Ben runs to the car.
EXT: STREET - NIGHT
Ben's at Kevin's car. Julie's gone. He searches the area. He pauses. He kicks the berry bushes. He heads inside the front door of Cooper's house.
