Ester

Author's note: Sorry for the slow pace. I assume that you have watched Ben 10 Omniverse, but I still need to provide enough details in case someone hasn't.

Ben and Rook went through the tunnel and came to Undertown. Rook observed his scanner. The fusion device appeared to be nearby. At that moment, Ben spotted something peculiar.

Ben: "Uh, Rook? Don't bother with your scanner."

Ben and Rook see the thief girl running on the pipelines overhead. They grappled onto the pipeline and followed her. Soon, they reached a dead end.

Ben: "Hold it!"

The thief girl: "You turned human. Do you finally listen to my advice?"

Ben: "You should care about your own situation. We're the ones who have the right to question here. What's your name?"

The thief girl: "Oh, the first step to make a girl your girlfriend. Olay, I'm Ester."

Rook: "Ester, hand over the fusion engine, please."

Ester: "What if I told you I couldn't?"

Ben: "It's not a matter of "could". Two of us, one of you."

Ester: "You sure?"

A group of people emerged from the shadow and walked towards them, equipped with weapons.

Ben: "Who are you?"

A man who looked like the leader replied: "We're the Kraaho. I'm Seebik."

Next to him, a man said while shivering: "Uh, can we do this quickly, Seebik? I can see my breath."

Ben: "You're cold? What's your problem?"

Seebik: "You're the one with the problem. The fusion engine now belongs to us."

Ester smirked, she took the container and threw it to Seebik, who caught it with his elastic arm.

Ben: "Is everyone around here made of rubber?"

Ester laughed: "Only the winners."

Seebik: "Ester, stop talking to that cold-cut! Back to the hot spot!"

Ester winked at Ben: "Let's do this again sometime... This or anything else, I guess."

Then she and other Kraaho disappeared into the shadow.
