It was now dark and everyone was now asleep. Everyone, except for a lone Saiyan who was staring at the sky through a window once more. He didn't feel the effects of the full moon anymore which was speculated to be caused by his newly acquired transformation. He didn't know why he was up at the moment but he couldn't seem to get any sleep. He heard someone shift in his makeshift bed that was laid out on the floor next to several others. The majin girl got up and rubbed her eyes, noticing that her humanoid teddy bear was wide awake.

"Kuzuku why are you awake? You should get some sleep, your injuries will recover faster that way." 21 yawned. Kuzuku was shook out of his thoughts smiled at her innocent question.

"No particular reason. I've just been thinking that's all." Kuzuku smiled. 21 raised an eyebrow.

"Thinking about what exactly? About the delicious food you scuffed down earlier." 21 teased. Kuzuku laughed at her jester.

"Maybe, but that's not quite it." Kuzuku said

"Then what is it then?" 21 who was now curious, questioned further.

"Well, after so many years, I finally was able to take revenge over Nana's death and despite that..." Kuzuku paused. 21 was now fully wondering on what the problem may be now.

"Despite that I still feel empty. As if taking revenge didn't quenched the feeling of losing Nana even after all these years of trying to forget." Kuzuku admitted. He realized that taking revenge did absolutely nothing to satisfy his grief. He still felt solemn over what had happen. 21 pulled Kuzuku into a hug, making the Saiyan to instinctively hug her back.

"Its okay if you need a shoulder to cry on. You must of been holding it in all these years. The feeling of grieving any further and trying to put on the best happy going impression since that day. So now that no one is aware or awake, how about you let it all out?" 21 smiled. Kuzuku began to shake, eventually giving in. He began to cry on her shoulder. The pent up emotions of grief that were postponed after Nana's burial were being let out like a river flowing into the ocean. This continued until the two fell back to sleep again, this time in the embrace of each other.

Next Day

The gang was loading supplies that were provided by the villagers onto the ship as they were getting ready to take their leave. The damage that has been caused had been reversed thanks to the dragon ball used on Earth. When they finished they faced the hoard of villagers that were seeing them off.

"Thank you for your generosity Elder. I hope that someday we meet again." Kuzuku bowed.

"No my boy, it should be us that should be grateful to you and your friends. If you haven't appeared on this planet then everyone and everything would of been destroyed." Kashu said. A little boy came running to the Saiyan with a piece of paper. Kuzuku was confused on what he was doing when he stopped in front of him, handing him the paper in his hand.

"I drew this for you! I hope you like it!" Said the boy as his mother pulled him back and apologized. They walked away, leaving the dumbfounded Saiyan with the picture. He took a look at it and smiled. A childishly drawn picture of him in Super Saiyan 3, beating up Aereos. Kuzuku folded it up and put it in his back pocket. He felt that he's been finally accepted by the villagers that despised him for so long. The gang boarded the ship and waved their goodbyes to the people of planet Codia and having their ship to departure off, leaving a small twinkle in the sky as they make their way back home.

4 Days Later

Goku, along with everyone else were standing in the landing zone in Bulma's yard. Kuzuku's friends heard the new that they've defeated Aereos and were coming back home today. Goku was getting a tad bit impatient until he felt a familiar ki signature approaching fast.

"About time they've arrive." Goku said out loud. Everyone except Vegeta, Goten, and Trunks were confused by his sudden claim. The ship was made visible in mere moments as it was descending fast until it stopped immediately at the platform. It slowly touched the ground before starting to power down. Everyone began to wait with anticipation as the door slowly opened. Out came first was Piccolo, followed by Gohan who was accompanied by Zugo, Hudo, and Riley. Last but not least was 21 and Kuzuku. Everyone ran over to congratulate them on their return.

"Congratulations on your victory guys! I knew you could do it!" Goku cheered.

"Yeah, you gotta be tired from being one so long. We've set up everything for your guys return party!" Bulma said.

"Wow that's awesome Bulma! I can't wait to eat some good food! I would of eaten on the way back but a certain someone kept eating all the food 21 made for us." Gohan said referring to Kuzuku.

"Hey, its not my fault you guys don't make it to the kitchen fast enough." Kuzuku teased. Everyone laughed and went on to enjoy the party. Bulma was having some girl talk with the gals (That includes 21) while Kuzuku's friends were practically dancing to the music. Piccolo did his usual meditation thing while Gohan was reading one of his books. Krillin and played with the kids as 18 watched in amusement at her husbands antics. The full blooded Saiyan trio on the other hand were chowing down along with Majin Buu, like there was no tomorrow. As they were eating Kuzuku took notice of Goku staring.

"Hmmm? Whpht is it Goku?" Kuzuku asked with a mouth full of meat. He swallowed it down and wiped his mouth with a napkin. Goku slurped up a endless stream of noodles and swallowed it whole. Vegeta cringed at the sight and nearly choked on his food, causing Kuzuku to give him some water so he can swallow it easier. Vegeta gladly accepted and chugged down the glass in seconds. Kuzuku then turned back to wait for his answer.

"Okay now that's settled, mind telling me whats up?" Kuzuku asked again.

"I heard from Elder Kai that you've unlocked an unseen form. He said he calls it a Super Saiyan 4." Goku said. Vegeta began to raise an eyebrow.

"Is that what's it called? Well I guess it sounds about right but to answer your question, yes I did and I used it to defeat Aereos in matter of seconds." Kuzuku answered

"Great, mind showing me its power?" Goku asked.

"Uh sure thing. I think I can transform into it again." Kuzuku agreed. Goku motioned Kuzuku to fly over to a barren area with Vegeta following suit. Everyone took notice of this and got in one of Bulma's jets and chased after them. They then found themselves at a rocky plain with high winds. Bulma let everyone off the ship to go see the sight of two Saiyans facing each other. It was a good thing Kuzuku was already wearing his combat Gi. He was stretching his legs and once finished, got into a more offensive stance. Goku smiled as he was ready for the challenge he was about to face. Vegeta flew next to the group, mostly making sure that his wife was going to be endangered.

"Vegeta, why did you guys suddenly fly off to the middle of nowhere?" Bulma asked.

"It seems Kakarot want to test out Kuzuku's new found strength." Vegeta uttered

"Hmm? Do you mean his training with Whis? I mean, I know he's probably gotten stronger but you guys have Super Saiyan Blue right? Are you telling me he's achieved it to?" Bulma asked but was interrupted by Kuzuku's voice.

"Alright Goku so how are we going to start this?" Kuzuku questioned.

"I have an idea. How about we go right off the bat?" Goku said. Blue aura coated his body with godly light, eventually bursting, revealing him in Super Saiyan Blue. This was the first time that Kuzuku was able to accurately feel the power of this form. He was simply amazed and even thought that if Goku or Vegeta were on Codia with him, then Aereos would of gotten destroyed effortlessly.

"Now it's your turn Kuzuku. Show me that new power." Goku smiled. Kuzuku closed his eyes and thought back to how he transformed into a Super Saiyan 4. He remembered how it felt and started to power up, flaring his energy to its limits before bursting into a giant dome of light. It then burst instantly, revealing smoke that circulated the area. Everyone stared for a moment before finally catching the glimpse of a golden light standing in the center. Kuzuku's Gi was blown off but revealed his red fur and orange iris with black pupils. His hair longer and was similar to a Super Saiyan 4 Goku except two bangs stood over his face.

"So that's the form Elder Kai mentioned?" Vegeta muttered.

"Vegeta what is the meaning of this?" Bulma asked. Gohan decided to explain.

"You see, when we were fighting Aereos, he was practically beating all of us at the same time. Kuzuku at Kaioken x10 was the only thing that could compete with him but still that wasn't enough. Somehow later, he transformed into a Great Ape and lost all sense of himself. He was brought back by 21 and all of a sudden he transformed again into what you see now." Gohan explained.

"So this is some new Saiyan evolution?" Bulma asked. He nodded to affirm her question.

"So what do you call this one?" Chi Chi asked a bit annoyed that yet another Saiyan transformation appeared.

"According to Elder Kai, he says that it is called a Super Saiyan 4." Vegeta said.

"Super Saiyan 4 huh? Well I know one thing is for sure and that is his power is simply incredible!" Krillin awed. Goku and Kuzuku stood face to face, smiling as they wait to get this fight started. The air was thickening by the pressure of their two strongest forms squaring off against each other. Kuzuku charged at the blue hair Saiyan, pressing his fist against his blocking forearm. Goku moved his hand aside and kicked Kuzuku in the ribs. He grunted as the kick stung a bit but eventually cast it aside. Goku was impress that he was able to take such a blow. They broke out into a exchange of strikes, each one being deflected and parried. Kuzuku broke the exchanges and landed a overhead kick. He then elbowed Goku in the cheek while following up with a reversed kick to his side. The red-furred Saiyan proceeded to uppercut him in the chest, launching him into the air. Kuzuku went in for a kick but missed when Goku vanished from his sights. He read the blue hair god's movements and countered his roundhouse kick with an elbow, generating a shock-wave. The two vanished again and countered each other once more, this time Goku launching a knee and Kuzuku hurling a punch. The Saiyans disappeared once more but were seen as blurs when clashing against each other. Kuzuku flew around Goku's punch and slammed him back to the ground but it had no effect at all as he landed on his feet, leaving a cracks beneath him. Goku looked up and launched a energy wave at Kuzuku but was dodged rather easily. Kuzuku then generated and fired three Ki orbs at the blue saiyan, each one being dodged as he jumped backwards for each one. Kuzuku appeared in front of Goku, launching ten punches that would be countered by Goku's fists. The Super Saiyan 4 kept up his onslaught and delivered a barrage of punches that would be blocked by one hand. Seeing this, the red-fur saiyan vanished and overhead kicked Goku in the back and appeared in front of him to elbow him in the chest. Goku tanked the hit and blasted him away, causing Kuzuku to slide back as he was getting pushed by the blast. When he deflected it upwards and was able to block Goku's fist in time, leaving a large blast mark behind him. With rapid movements, they once more parried each other with their strikes. Goku's kick was blocked by Kuzuku hand. Kuzuku's punched was stopped with a cross-counter. Goku's high kick was blocked by Kuzuku's forearm. It then stopped when they clashed elbows and struggled for control. Kuzuku broke the hold and fired several Ki blasts, causing Goku to defend against each one. This left him wide to a kick to the stomach, forcing his guard to drop. Kuzuku followed up with a knee to the face and punched him away, instantly firing a Kamehameha. Goku flew upwards, dodging the blast and fired one of his own. Kuzuku saw it coming and deflected it away and proceeded to fire a barrage of Ki blast through kicking. Goku dodged the first four and deflected the last before flying from above to meet Kuzuku's fist with his foot. This created yet another blast mark beneath them. The two vanished and clashed in a series of punches and kicks as they flared their energies, eventually breaking apart.

"Let's wrap this up shall we?" Kuzuku said charging up his Kamehameha

"Agreed, lets end this." Goku said.

"X10 Kamehameha!" Kuzuku yelled

"HAAAAAAAAAAA!" Goku fired. The red and blue beams collided like fire vs water. Kuzuku then felt himself slipping as Goku was putting more force into the blast while he was trying his hardest to fight back. Goku made one last push resulting in Kuzuku's beam to be overpowered. The wave engulfed Kuzuku, damaging him as it passed before dissipating. Kuzuku stood still for a moment and muttered.

"Incredible..." before deforming and passing out. Goku landed on the ground panting a bit before deforming himself. He walked over to Kuzuku and gave him a senzu bean, allowing him to wake up and recover instantly. The tailed Saiyan dusted himself off and exhaled deeply.

"Man, despite achieving a new form, your still one step ahead of me." Kuzuku said.

"Well that's probably because of Super Saiyan Blue. If we were to fight at any other level then I may of been beaten. That goes to say that you may be stronger in terms of normal Saiyan power." Goku chuckled

"Yeah but I feel that there is more to a Super Saiyan 4 than it meets the eye. I mean I did gain a stronger boost compared to using Kaioken x 10 but something feels like I haven't begun to tap into its potential." Kuzuku said. Goku smiled at his enthusiasm. They walked back to the group her were by the ship.

"Sorry for leaving guys. I just wanted to see how strong Kuzuku's gotten and oh man that Super Saiyan 4 is something else." Goku laughed. As Goku was being his usual cheering self, Kuzuku could only watch as he knew that he was holding back by a lot.
