Maddison Matthews, best friend of Leo Dooley.
She looks like a normal girl, but she's hiding a big secret.
She is not human.
What will happen once she meets Adam, Bree and Chase?
I don't own the Lab rats and Arrowverse charac...
A couple of seconds later, Reign ran towards the heroes. She punched the heroines against the door of the elevator, making them bend.
As much as Chase wanted to help, he knew he needed to help Lena make the cure instead.
So, he and Valor rushed towards the Luthor woman with the rock.
The Worldkiller used her sonic screams on the D.E.O. agents present, making them fall.
- "We'll keep her busy." The Matthews man said.
- "Come on." The Davenport boy rushed to the table with the green-eyed woman.
They started to work on the cure.
Tim used his elastic arms to trip the villain, before she grabbed his arm and spun him around, until she let him go to crash until a wall.
- "Ugh." The Davenport man from the future groaned, in pain.
GreatGirl's eyes turned red as she super speeded towards Reign to grab her and throw her through the ceiling of the small room she has inside the big secret lab.
All the heroes looked around as the Worldkiller had disappeared.
Suddenly, she appeared behind Supergirl and threw her at a table across from the one Chase and Lena were working on.
The Daxamite clenched his jaw and rushed towards the villain angrily. He jumped on her, crashing through a wall of the small room with her.
The hybrid helped the Danvers woman up as Valor tried to punch Reig, but she dodged his fist.
The Matthews girl tried to do the same, but her arm was blocked, and she got punched instead.
The Matthews man kicked the Worldkiller in the stomach.
The blonde punched her chest.
The villain tried to grab Tim, but he stopped her arm and hit her throat with the side of his hand.
She coughed for a moment, before she started to attack them again.
The quadbrid grabbed her arm with her cape, as the Daxamite grabbed her foot with his own cape.
They both pulled simultaneously, making her spin in the air until she hit the ground.
The two scientist finished the cure and put it in a needle.
Supergirl and GreatGirl both grabbed Reign, keeping her still.
The bionic boy slid the needle on the ground to his brother-in-law.
Valor grabbed the needle and stuck it in the Worldkiller's neck, making her scream in agony.
The Davenport man from the future, quickly, pulled the heroines away.
Bright orange veins appeared on the villain as her eyes turned into the same color.
