Chapter 1: Training Begins and a New Evil Rises
Two years have passed since the fateful battle between Goku and Frieza, and a lot of events have taken place during that short amount of time. The Z Fighters used the namekian dragon balls to resurrect those who were unable to be resurrected twice with the Earth's own dragon balls, restore Planet Namek (now called New Namek) and finally transport all the namekians back where they rightfully belong.
Also Frieza came back, as a cyborg and tried to get his revenge against Goku by killing him on Earth, with his father, King Cold as his back up. Long story short, both Frieza and King Cold get sent straight to Hell by the hands (or sword in this case) of Future Trunks, a teenage saiyan hybrid from the future who warns the Z Fighters that in 3 years time, two androids will destroy the world if they're not stopped. Goku finally returns home from Planet Yardrat, with a newly learned technique called Instant Transmission, a technique where one can sense a person from miles away and instantly teleport to his/her location, then Future Trunks continues by saying that also Goku will die of a deadly heart disease that wouldn't be cured until years after he dies, luckily Trunks was able to give the cure for the heart disease Goku will have to take when he needs to. So Trunks then leaves and now the Z Fighters will start to prepare for the arrival of the deadly androids, to Chi-Chi's dismay, since Goku and Gohan will be training for the event.
So, where are they now?
Several months have passed and everyone is doing well with training, especially Gohan since he has both his dad and Piccolo to train him near his home Mount Paozu.
Right now, Goku is teaching Gohan how to keep up with his opponents at high speeds since he will have to be super nimble when going up against the androids.
BOOM! BAM! POW!
Both father and son, creating sonic booms all across the sky and the very ground of the Earth itself shakes due to the intense training that's taking place.
Then, it all just stopped. With Goku looking rather unfazed compared to his son, who is about a few seconds away from fainting.
"Phew...How am I doing Dad?" Gohan said in a out of breath manner.
"You're doing great son!" Goku exclaimed, "I'm impressed that you can catch up with me at such a young age."
"You have to thank me for that Goku, without me, Gohan wouldn't have made it this far after Vegeta and Nappa's attack on Earth." Piccolo said confidently.
"Speaking of which, where is Vegeta?" Goku curiously asked, "It's really been a while since we've heard from him."
"Last I heard, he's been training at Bulma's house" Piccolo stated to Goku. "I still don't why she even puts up with that arrogant prince, after all he's done to us."
Bulma's Gravity Machine Training Room
"Huh!?" "Why do I get the feeling someone is talking crap about me?" The saiyan prince exclaimed, "Oh, when I catch the culprit, I swear to Kami, there will be hell to pay!"
Back to Mount Paozu
"Maybe Bulma sees something inside Vegeta that we cannot see at the moment, besides he inadvertently helped us out with the Ginyu force and Frieza."
"Until he got his ass handed to him that is." Piccolo retorted, "Anyways, Gohan now it's time to teach you one of the most important things to do in a battle, how to dodge."
"Oh brother, here we go." Gohan groaned.
"The trick for dodging attacks is to always expect the unexpected."
"But how would I know to-" Before Gohan was about to finish his sentence, suddenly, a giant ki blast was heading towards him!
"Woah!" Gohan exclaimed while narrowly dodging the blast. The blast ended up destroying a large boulder near the training grounds.
"Like that." Piccolo said with a smug look on his face, looking rather pleased with himself.
Meanwhile, on a far off planet in the outskirts of the universe...
There lies a ship that looks just like one of Frieza's own ships, but instead of Frieza coming out of the ship, three soldiers come out of the ship. One was a tall, brown, reptilian like alien named Neiz, the second one was a large, muscle bound, green skinned humanoid alien named Dore, and the last one was a turquoise skinned humanoid alien named Salza, who was not only smaller than Dore and Neiz, but he's the commander of the two soldiers.
However, when they walk towards this throne that stood in the middle of nowhere, they start to bow down to the one who was sitting on the said throne. He was a tall, deep-purple skinned, lean-built alien with several armor-like carapaces on his head, shoulders, shins and chest, a long tail, and a pair of menacing blood red eyes that can pierce into one's soul.
"My Lord, I regret to inform you that both your younger brother and father have been killed." Salza explained to his master.
The mystery man just sat in silence for what had seemed like forever, until he finally responded to Salza's unfortunate news.
"Is that right?" The mystery alien exclaimed, "And who was responsible for my brother's death?"
Salza froze for a second or two, worried about his master's reaction to what he was about to say next.
Then he spoke in a rather frightened manner, "It..it was...a saiyan my Lord."
"I knew that would be his ultimate downfall one day, this what happens when you spoil your child, father." The alien exclaimed in a rancorous tone.
"Salza, do you have any other information on this saiyan?"
"It would appear that this saiyan is from a planet called Earth."
"Very well then, set the course to Earth, It's time to do what should've been done all those years ago."
Then Salza felt the need to ask his master,
"Are going to avenge your brother my Lord?"
Suddenly his master stood up out of his throne and then proceeded to destroy it with a ki-blast before replying..
"I could honestly care less about my incompetent brother, all I care about is restoring honor to my family name, and that saiyan who killed my brother shall fear the name of Cooler! The first born son of King Cold and the new supreme emperor of the entire universe!" Cooler vigorously exclaims.
"And vengeance my fair henchman…Is a dish best served COOL."
