Zaiko

"*Your tenacity is admirable, but it only prolongs the inevitable.*"
— Zaiko to Enemy 1

Tobashi (uncle)

Belseria (grandmother)

Sayuki

**Zaiko** (ザイコー*Zaikōh)* is a half-breed and one of the most powerful characters in the Ultra Ball series. He is the son of Kado Ryuuga and Rena, and the nephew to Tobashi & Takadon.

Like his father, he wishes to travel the Multiverse, alongside his mother. He also fights alongside them when the time calls for it. He possesses a special power that gives him a spot among the strongest warriors.

## Concept & Creation

The concept for this character is inspired by several different characters: **Broly**, **Goku Black**, and **Meliodas** from the Seven Deadly Sins.

## Personality

Like his parents, Zaiko possesses a sheer force of willpower that allows him to keep pushing himself. However; he’s adapted Kado’s habits of distancing himself from others - if he’s not spoken. Showing that he too has social anxiety. Though; he’ll be himself around people he’s familiar with including his comrades.  He can be enthusiastic, enjoying being around his loved ones as they’ve become his reason to get stronger - to protect. His Saiyan characteristics have him eager for the next fight, wanting to train with his parents every chance he can get to be just as strong as them someday. There will be times where he becomes arrogant or too proud of his strength if he manages to succeed in battle. Kado reminds him to not get too full of himself as there will always be someone over him, including himself in his statement. However, that doesn’t stop Zaiko.

In the midst of battle, Zaiko can get overly excited to the point where he could be perceived as sadistic. He’s aware that his pain will turn into power. If he’s in a situation where he’s losing to an enemy, he would memorize that feeling and become driven to see the battle all the way until he or his opponent is down for the count. This is due to Rena’s aggressive nature and Kado’s negative traits, making him a force to be reckoned with. He will get easily irritated if he or anyone in his inner circle is on the verge of being hurt which will make him react out of anger.

## Biography

Rena was pleased when Zaiko was born since she had been able to give birth to a newborn boy. She promised to raise him to be a fantastic warrior. Kado was overcome with emotion; he didn't know how to show his happiness for his first kid, whom he helped with basic needs during his early years of existence. He had no idea what to do in this situation; this was a completely new experience for him. Sayuki helped as well, and she was overjoyed that they were starting their own family. Despite the fact that she was not her actual mother, Sayuki promised to do everything she could to protect Zaiko. She could see Kado's enthusiasm as she mocked him for it, forcing Kado to shift the subject every time. When Zaiko was able to walk, he unconsciously began flying on his own; unfortunately, he lacked the control to modify his direction, leaving him doomed to crash on his face. The kid's quick development astounded Kado, Sayuki, and Rena. When Zaiko was a youngster, his emotional instability activated the telekinetic energy within his head, causing everything around him to rattle, shatter, and/or break. Kado saw that Zaiko had been endowed with the capacity to employ Psychokinesis due to his Kadonian ancestry. Rena made the joke that Zaiko and Kado may be twins because they were both part Saiyan and part Kadonian. Sayuki thought it amusing, but Kado did not, so he walked away in an attempt to put an end to the talk before it progressed any further. Sayuki and Rena both agreed that Kado adored Zaiko but refused to declare it since his pride prohibited him from doing so. Especially when he found it difficult to express his feelings.

When Zaiko was 7, Rena taught him the fundamentals of battle while Sayuki instructed him on various fighting methods and Ki Control. She taught him Karate, Judo, Muay Thai, and Aikido as part of Rena and Sayuki's lessons. Despite these training sessions, Zaiko's body was thrown through the wringer over the first several weeks, but each time he returned stronger than the day before, improving his bodily functions. It wasn't long until he had a well-defined physique for a child his age. Kado was first hesitant to work with Zaiko because he was used to training alone. Rena and Sayuki, on the other hand, persuaded him to reconsider. Zaiko learned how to use his Telekinetic Talents by exhibiting his own abilities after Kado left to welcome him in to train: Using his mind power, he was able to move ordinary items and lure a glass to his palm. Zaiko had a migraine only from using it a few times. In that time of pain, Zaiko was curiously delighted to experience it, leaving Kado perplexed as Zaiko inclined his head, saying that the suffering would make him stronger, which he confirmed with a nod of his head. Zaiko was overjoyed to hear this, so he hugged his father and left Kado dumbfounded. This gave Zaiko hope that he may become a great fighter one day.

As Zaiko got older, his adventure continued…

"*Incredible… he’s grown so much in just four years… I remember back when he was just 7 struggling to control his flying.*"
— Sayuki to Rena & Kado

Despite being a teenager, Zaiko has shown to be a prodigy with unusual intrinsic skill and development, much like his father. When he was smaller, he began flying subconsciously while Rena was playing with him. Furthermore, he inflicts multiple bursts of strength in his moments of rage, equaling his power level or even beyond his father’s power level when he was Zaiko’s age. This proved that Zaiko has a large room for growth as he gains more experience and grows, which only is shown when he’s in great emotional stress which causes him to either start showing the sadistic side of his personality or pure rage and anger - the condition varies depending on his condition prior to the transition. Losing most of his cognitive thought in the process, however; when he calms down the power buff decreases to its original level. However; this shows that Zaiko has the ability to draw out more of his potential, he just needs the right push to bring it out permanently. Being half Kadonian, he has the ability to manipulate Telekinesis along with a good amount of mental power, allowing him to heighten his sensory and perform different tricks with it. Even by normal standards, Zaiko has more body strength - like his mother, allowing him to use that raw strength to assist him in battle. Sayuki perceives the untapped potential lurking around in his body, declaring he’s going to be able to utilize more of that power as he gets older. However; for the times that he does reach the point where he’s too emotionally unstable, Sayuki created a crown that holds the power to restrain Zaiko right in his tracks, sending a high voltage shock through Zaiko’s bio. This idea was suggested by Sayuki as where Kado or Rena wouldn’t have to beat him back to his senses.
