It's over, it's finally over. Goku defeated Kid Buu with the spirit bomb that was made with energy of all inhabitants of the Earth. After many lost battles, the Z Fighters won the war. Thanks to our brave warriors we can live in peace again, but..
One and a half year passed since the death of Kid Buu, everything was peaceful again and life on Earth was going its normal and used way. Gohan was busy studying while Goku and Goten tried to spend as much time as possible together because Goten has not seen his father for seven long years.
"Daddy, can I ask you a question?" Goten asked as they were lying on the grass and watching the bright blue sky next to the river where they always go fishing. "Of course, son. Go ahead.", answered Goku. "Are you the strongest fighter in the universe?", asked Goten. It took Goku a few seconds to answer the question, then he smiled at Goten and said: "I don't know, son. Maybe I am, but maybe not. The universe is so big there could probably be fighters we have never heard about, but I'm not even sure if I am the strongest on Earth. You saw what your brother did to Buu before he absorbed Piccolo, Trunks and you. And Vegeta, he is always good for a surprise and hell of a fighter. I'm sure he is training at this moment. He is a very proud warrior. He would never admit it but he loves his family more than anything, he would die for them without thinking about it for a second. This love give him an unconceivable if his loved ones get in danger.". Goten looked a bit confused but didn't say anything. "Come on, son, let's see if Chi Chi and Videl are finished with lunch. Bet I will be there first?", asked Goku and started running. "Wait for me, daddy.", Goten replied and started running after Goku.
Meanwhile, Vegeta was training with Trunks in the gravity chamber created by Bulma's farther, Mr. Briefs. "Kakarot, we may be friends now, but that doesn't mean that I don't want to be stronger than you. I'm the saiyan prince and i have to be the strongest warrior in the universe!", thought Vegeta while throwing punches at 700 times stronger gravity. "Daddy, this is too hard for me. I am so exhausted I have to take a break." "It's OK Trunks, you can go train outside, see you later." Vegeta replied. " How did Kakarot manage to go Super Saiyan 3? I have been training for one and a half year at 700 times stronger gravity for 8 hours a day and still I'm not able to turn to the next level. Of course I got much stronger than I was when fighting Majin Buu, but Kakarot is still better than me. Even his elder son is way stronger than me,the ritual of Old Kai gave him enourmous powers. I think he is even stronger than a Super Saiyan 3. Goku had also no chance against Buu with Gotenks and Piccolo absorbed.", suddenly Vegeta got interrupted by Bulma: " Vegeta, you have been training now for seven hours. Why don't you come out of the chamber to eat something and relax a bit? You can later continue your training." Vegeta decided to listen to Bulma's recommendation and go for a walk to get his mind free.
Nobody has a clue what horrible thing is about to happen. Babidi, the magician that freed Majin Buu from his egg has a new plan for taking over the world. This time he has much stronger company. Like Dabura or Vegeta one and a half year ago, this time he has Frieza, Cooler, King Cold, Cell, Broly, Bojack, and even Kid Buu under his control, calling them the Majin Fighters. They are much stronger than before Babidi transformed them into their Majin form. "So master Babidi, how will we manage to break out of hell?", asked Majin Cell. "Be patient Cell, we are the strongest army in the whole universe. Nobody can stop us this time, I will reign over the whole world and revenge for what this guy called Goku did to me!", yelled Babidi. "Don't worry master, i have some unfinished business with Goku, he embarrassed me on Namek years ago and now he is going to pay!", said Majin Frieza. "Kakarot, this time I'm going to kill you!" added Majin Broly shouting.
