Lifts and swings a Dragon Ball that's weight increases from a small mountain to a small planet

The alien youth's face turned completely transparent and both golden spheres glowed with a green light. Suddenly, Gohan felt his dragon ball being pulled straight down. He started to shift it to his other hand to get a better grip, but realized it wasn't being pulled—it was simply far, far heavier than it had been an instant before.

Across the Lookout, Vegeta grabbed the ball with both hands, beginning to strain. It was hundreds...no, thousands...no, tens of thousands of times heavier, and was growing heavier by the second.

"You wanted to test the limits of your strength against the limits of my magic?" asked Majcnavn coldly. "Well, here you go. Right now, both dragon balls weigh as much as a small mountain. In a few moments, they'll have the mass of an average comet. I wonder: will they slip from your fingertips before or after they weigh as much as the moon?"

Gohan's muscles bulged, and his aura flared brighter as he willed himself to maintain his grip. How could something so small be so heavy? If the ball was larger, he thought, it would be easier to keep his handhold, but he didn't know how much longer his strength would last.

The prince had dropped to one knee and was clutching the dragon ball with both hands, the muscles and tendons of his shoulders and back pulled taut. Even so, he grinned. "Is this...the best...you can do?"

Majcnavn smiled darkly. "The balls are now heavier than the average asteroid," he said. "How much more strength do you have?"

Vegeta forced himself up to a standing position. He had locked his fingers around the ball and was straining even more. "What do you expect me to do? Throw it to you?"

"That would work, yes," laughed the dragonspawn.

"Fine." The prince powered up even further, and began spinning around in a circle. Arcs of electricity crackled around his biceps and chest as he started turning faster and faster in place.

"Don't do it, Vegeta!" shouted Gohan. "As soon as you let go, he'll just teleport it to himself! He wants you to throw it at him!"

"The boy's right," replied Majcnavn, "but if that's what you insist on doing, I won't stop you."

The older Saiyan said nothing. His eyes were closed as he spun in place more and more rapidly, the ball whirling around in his grasp like a stone in a sling.

"YOU WANTED TO TEST MY STRENGTH?!" shouted Vegeta with exertion, his arms a blur as he whipped around and around. "WELL HERE...YOU...GO!"

Majcnavn raised one hand, readying himself to catch the ball. But then there was a flash of lightning and Vegeta vanished.

"Whaaa—"

Vegeta rifted into view right next to him.

CRRRAAAACCKKKKKKKK!

The dragon ball smashed into the side of the dragonspawn's head with the momentum of a small planet. He skidded across the tile, nearly falling off the edge before he could stop himself. When he reached up, he felt blood pouring down the side of his head and out of his nose. His vision swam and he felt an overwhelming sense of nausea. He probed the wound, and his fingers came away with splinters of bone clinging to them.
