Outside Earth.
At that moment, a "small asteroid" was heading toward Earth.
This "small asteroid" was called the Dark Planet, a "planet" made up of large amounts of discarded machinery.
The person who had created this planet was a Tuffle named Dr. Lychee.
Dr. Lychee had originally been the top scientist on Planet Tuffle. When the Saiyans wiped out the Tuffles, he completed the Destron Gas Amplifier, Hatchiyack. He had planned to flee Planet Tuffle with the device, but the Saiyans killed him before he could escape.
Later, he was "revived" by the Destron Gas Amplifier he had created, and began carrying out his plan to take revenge on the Saiyans.
The Death-Extinction Qi on Earth was his doing. He had launched missiles to drop devices that released Death-Extinction Qi onto the planet.
Dr. Lychee now knew that someone had destroyed the Death-Extinction Qi devices he had deployed on Earth.
"Damn it! I never thought those Saiyans would act so quickly. They've already destroyed the devices I deployed on Earth!"
Dr. Lychee clenched his fists and spoke furiously.
Just then, a figure suddenly appeared in front of Dr. Lychee.
It was Son Gohan.
"S-Saiyan!"
Dr. Lychee was startled.
He hadn't expected Son Gohan to find him so quickly.
Son Gohan looked at him coldly.
"The Death-Extinction Qi on Earth was your doing, wasn't it?"
Dr. Lychee immediately burst out laughing.
"That's right! I'm going to use Death-Extinction Qi to wipe out you hateful Saiyans!
"If it weren't for you hateful Saiyan monkeys, the Tuffles wouldn't have been wiped out. I'm going to avenge my people!"
"Is that so?"
As he spoke, Son Gohan gathered golden energy in his right hand and fired it at Dr. Lychee.
Dr. Lychee was startled and hurriedly formed a green barrier in front of himself
