Roxy felt a blast of heat. An orange bubbling liquid covered the floor.
"Lava, hot!" Bippo said.
A walkway extended over the lava, connecting to a large platform. A gigantic robot stood on the platform.
Wukong gulped. "That's the biggest demon I've ever seen!"
Cozlin's eyes were wide. "Meltron!"
Roxy flew up, floating in front of the giant robot's face. "We're here to destroy you, Meltron!"
"Someone else tried to destroy me once," Meltron said. "It didn't work."
Roxy raised an eyebrow. "Huh?"
"My creator threw me away," Meltron said. "I was much different back then. I was getting old and a bit rusty. My creator built a new robot and tossed me into a pile of scrap metal. I might have been a simple farming robot, but I was smart. I fixed myself. Over the years I've made myself bigger and stronger. And I've made sure that nobody will ever throw me away again!"
"Your robots are destroying planets!" Cozlin said.
"Bad, you!" Bippo said.
"The planets are fine," Meltron said. "But I assume you're upset because living things can't survive on them anymore. Living things get rid of robots and other machines all the time. Now it's time for robots to get rid of living things!"
Suddenly dozens of robots flew into the room. They shot toward Roxy and her friends. Wukong swung his iron bar. One robot shattered and fell into the lava. More robots attacked him. Wukong flipped through the air, twirling his iron bar in every direction.
Whiz-hoo! Roxy's eye laser beams blew up a robot. A piece of it hit a second robot, and they both splashed into the lava.
Cozlin leaped into the air. Roxy watched as Cozlin seemed to disappear. All Roxy saw was a blur zipping back and forth. Everywhere this blur went, robots exploded.
"Wow!" Roxy thought. "Cozlin is really fast!"
A robot grabbed her arm. Bippo fired a laser. Pew! The robot exploded. Boom!
"Nice work, Bippo!" Roxy said. But then she groaned as more robots flew into the room.
"There are too many of them!" she thought.
Meltron laughed. "You'll never stop me!"
"We'll see about that!" Wukong leaped toward Meltron's head. He muttered a spell and became tiny. Then he squeezed through a small hole in the side of the robot's head. Wukong looked around. Strange glowing objects hummed and buzzed all around him.
"I have to find that controller!" Wukong said.
"Your Majesty!" A government worker ran into King Radnik's office in the bunker. "We just received a message from our allies in the Quill Region. Three more planets have been invaded by robots!"
King Radnik bit his lip. "This is bad!"
On Hulzar, the portal makers hid in their laboratory. The robots' drills rumbled above them.
"Those robots will reach us soon!" Flix said.
As Roxy battled Meltron, she heard her watch beep. "Mayor Bloom! What's wrong?"
"We have a big problem, Rocket Girl!" The mayor walked to the window of his office. Roxy saw robots in the street.
"Oh no!" Roxy cried. "Meltron's robots are invading Earth now!"
