Roxy gasped. "Dr. Chen could be Brain Invader!"
General Waltz nodded. "I think she is."
"Don't worry, General," Roxy said.
"I'll stop her. First I have to catch Private Benson and Mighty Man.
They stole a lot of . . . General Waltz?"
The general was gone.
Roxy scratched her head. Then she groaned.
"Ugh! He tricked me! Maybe he's Brain Invader.
I hope Dr. Chen's okay."
She opened her watch and called Dr. Chen.
The scientist didn't answer.
Roxy flew to the lab.
She went inside and looked around.
"Rocket Girl!" Dr. Chen was locked in a cell.
"I'm glad you're here! General Waltz is Brain Invader!
He locked me in here!"
Roxy opened the cell door and bit her lip.
What if General Waltz was telling the truth?
What if Dr. Chen was lying?
"Ugh," Roxy thought. She didn't know who was telling the truth!
"General Waltz said that you're Brain Invader," Roxy said.
"He said you refused to use the cure."
Dr. Chen sighed. "I was going to use the cure.
But he controlled my mind and made me stop.
I had several doses of the cure on my workbench. He stole them."
Roxy took a deep breath.
"I believe you. But how will we stop General Waltz?"
Dr. Chen smiled. "I have one dose left.
I hid it in my pocket."
"You're a genius!" Roxy said.
Dr. Chen chuckled. "Well, I am a scientist."
"I'll cure General Waltz," Roxy said.
"Then he won't be able to control anyone."
"He's probably at Army Headquarters," Dr. Chen said.
"But if you go there, he'll control you."
"Nope!" Roxy said. "Steel blocks his power.
I hope you don't mind. But I need the steel from this cell."
"Go ahead," Dr. Chen said.
Whiz-hoo! Roxy's eye laser beams cut a piece from the wall.
Using her heat vision, she heated it up.
It grew soft. She bent and twisted the steel.
Soon she had a helmet.
Roxy kept working.
A few minutes later, she wore a shiny steel suit.
"Now the general can't control me."
"Perfect!" Dr. Chen gave Roxy the device.
"I'll make more doses for Private Benson and Mighty Man. Oh, and the skunk."
Zoom! Roxy shot out of the lab.
She flew toward Army Headquarters.
"Stop right there!" a voice shouted.
Roxy gulped. Dozens of soldiers blocked the entrance!
