Tyranny of Lord Yao
After a few weeks of training with her brother and cousins, Pan informs them that King Yao is rampaging and has gotten stronger than ever. Wanting to test their strength, they go off to find the Demon King. As they landed in the northern side of Mount Paozu, they see Yao terrorizing a village. Goku Jr quickly jumps into action and kicks him in the face. After regaining his balance, Yao transforms his arm into a sword and attacks Goku Jr. Chi-Zu, who was absolutely worried, told Tora and Riku to help him. All three flew up to help their cousin, with Tora firing a Kamehameha, Chi-Zu a Masenko, and Riku Special Beam Cannon. When they all hit Yao , he flew back into a mountain. Thinking they've won, Chi-Zu begins to cheer, until Tora ensures her that he's still alive. Yao then bursts from the rubble and fires his arm cannon at the Saiyans, who quickly dodged. Immediately they all turn Super Saiyan and attack the Demon King. But, as they tried to land punches on him, he blocks every last one of them. He then transforms his arm into a mace and bashes Riku and Tora into a mountain, smashes Goku Jr to the ground and kicks Chi-Zu into a boulder. As she, Tora and Riku unconscious, Goku Jr turns Super Saiyan 2 and kills Yao with a kamehameha. After they all regained consciousness, he quickly converts to his base form and lies saying that Yao fell into a lava pit. Riku then makes the realization that they just saved the world from destruction, making them the New Z Fighters.
Attack of Kuriza
A couple of weeks after the defeat of King Yao, the Saiyan quartet decides to go back to training. But their training is put on halt when they feel a massive power heading for Earth. They quickly head towards Gizzard Wasteland, where they found a space ship similar to Frieza's. Suddenly, a wave of soldiers pour out of the ship and attack the Sons. They quickly dispose of the soldiers and happily thanking them for the warm up. Kuriza then steps out of the ship and congratulates them for beating his soldiers. He then sees Tora and sarcastically asks how Ryun was. As the others were confused, Tora explains how Kuriza is the heir of the Cold family and how he and Ryun was kidnapped and how they escaped. Kuriza then attacks Goku Jr with his tail, sending him flying. Chi-Zu, Riku and Tora attack Kuriza, who dodges every attack. Goku Jr then gets back up and uses his Kaio-Ken and kicks him in the face, sending him flying. Stopping in midair, Kuriza then send a barrage of ki blasts at the Sons. Frantically trying to dodges the blasts, Goku Jr and the others use the After Image Technique to confuse him. Frustrated, Kuriza charged at them with a Destructo Disc, which multiplied by x12. As they dodged the discs, Kuriza got even more frustrated. Angry, he transforms into his final form. Sensing that he had surpassed their power, all 4 Sons transforms into Super Saiyans. As they attacked Kuriza, he easily dodges and blocks them. Soon, he starts thrashing them around, badly injuring them. Thinking it was their last hope, Goku Jr gathers energy for the Spirit Bomb while Riku, Chi-Zu and Tora stall Kuriza. As they continued to fight, Chi-Zu sees that the Spirit Bomb would take to long and tells Goku Jr to convert the energy into a Power Ball so she and Riku transform into Great Apes. Goku Jr and Tora become surprised at the decision, knowing that neither have experience with the form. After a few more minutes, Goku finishes the Spirit Bomb and fires it at Kuriza. After the dust cleared, Kuriza angrily shoots Tora with a Death Beam. He also tries to shoot Goku Jr, only for him to use his remaining power to block it with a kamehameha. Kuriza then fires another one, which is blocked by Ryun, who then slices Kuriza in lightning speed and finishes him with a kamehameha.

After given a Senzu Bean, Chi-Zu persuades Goku Jr, Riku and Tora to help her gather the drago balls to wish the killed soldiers back. Returning to the Son residence, they retrieve the 4 star dragon balls and the Dragon Radar. After Goku Jr and Riku retrieve two dragon balls, Chi-Zu goes to a jungle to find one. Soon, she was getting close to it, but a teenager by the name of SVX, grabs it before she can. Determined to revive the soldiers, she ordered him to give her the dragon ball. Seeing her tail, SVX implies that she is of Saiyan blood and tells her he was too and flies away. Quickly following him, Chi-Zu uses the Solar Flare technique. As SVX drops the dragon ball, she swoops down, catches it and flies away. Soon, she finds herself in a desert, where SVX is as well. As they race to the dragon ball, Chi-Zu asked him what he wanted it for. He tells her it's not her business. He then grabs the dragon ball and flew away in lightning speed. Regrouping with Riku, Goku Jr and Tora, Chi-Zu sees that the dragon balls are heading for a certain location. Quickly setting out for the dragon balls, Goku Jr and the others find Asper, Sharotto, and SVX with the dragon balls they have. Chi-Zu then threatens them to give them their Dragon Balls.
