Story
Captain Kaizo made his debut in Season 3, Episode 20 as an unknown, uncredited character talking to Bago Go and became one of two witnesses to Ejo Jo's escape.

He made another appearance in Season 3, Episode 24 with a more major role. He showed up with his spaceship to easily defeat his rival and his PETAI robots with the help of his alien, Lieutenant Lahap. Later, he threatened BoBoiBoy and his friends to hand over power their Power Bands and told Fang to fight with BoBoiBoy because of his refusal to hand them over.

After being defeated by BoBoiBoy and his friends with Fang's aid, Kaizo accepts his defeat before congratulates them for proving that they worthy with their said powers, and revealed that he was embarked on a mission to save the galaxy from a tyrant and required necessary resources to do so. He offered them to cooperate with the said mission, only for them rejected it due to his extreme ways. After returned them to Earth, he asks Fang whether he would return to him or stay on earth, in which Fang chooses the latter.

Before his departure, he warned BoBoiBoy that after him, the others would come to Earth, foreshadowing an epic battle between BoBoiBoy and his friends against Tengkotak.

Appearance
Kaizo a well-built individual with dark purple hair and bright red-magenta eyes. He dons a helmet-mask that can come down and cover his face at well. He has noticeable similar features with his younger brother, Fang. Since he greatly resembles a regular human being, it's hard to tell that he's actually an alien.

He wears a blue and purple trench coat, armed with white shoulder guards. Kaizo sports a golden watch with a cyan face and wears a pair of dark fingerless gloves. Around his waist, Kaizo wears a white belt with a orange hexagonal shape as it's buckle. He has dark ultramarine pants, the same color as upper shirt, decorated with patches of blue.

Personality
Kaizo is a strong, confident, and sometimes arrogant individual. He is not one to shy away from what others may deem immoral, including using violence to get his way. Kaizo is not easily intimidated by others and has been implied to hold his own against powerful aliens such as Bora Ra and Ejo Jo, making his name out as the 'Legendary Space Rebel'. Kaizo is confident and calculating and seen to be a very smart individual, as he was able to figure out that Fang had gone against him before he even revealed himself. Kaizo doesn't hesitate to use force to get what he wants, even to his own brother.Despite his cold demeanor, Kaizo is shown to be honorable, best shown when he offers BoBoiBoy's gang a second chance to fight him and Lahap to prove that they could keep the Power Bands. After seeing their full potential, he offers BoBoiBoy and friends positions in his team, but when they refused, he respected their decision and warned them of future dangers. Although he is quite cold and indifferent to the people around him, he has never mistreated Fang and shown to value his brother.

Skills and Abilities
There is a reason why he's known as the 'Legendary Space Rebel' and that's the proficiency and strength of his skills. He doesn't only on his powers of his mask, but also on his raw skills that he had learned, probably from a solider-esque background. Kaizo is shown to be incredibly agile and durable, even able to survive after BoBoiBoy and Fang's most powerful attack. He can also summon an Energy sword, which he uses along with his exceptional swordsmanship.

He derives his power from his masks and gives him the power of Energy Manipulation. With this method, he is able to a wide array of skills. With the mask, he is able to power up his strength, giving him the power to knock even the largest opponents away with a single punch or kick. With his Energy Manipulation, he can also enhance his speed, even to keep up with the likes of Thunderstorm, who is considered to be BoBoiBoy's most powerful form attack-wise. He can also overload objects with raw energy to cause them to implode. To protect himself, Kaizo can summon a barrier which can absorb most attacks.

His only known weakness is that Kaizo is unable to focus his energy on more than three targets, shown that when he needed to enhance the power of the sword, he had to disarm his energy handcuffs and shield.
