He now sports a golden watch on his right wrist with the face of the watch being cyan. The crevices to his silver-gray mask are neon blue. His belt buckle remains golden in colour as well as hexagonal in shape, but it seems to be attached to a white harness (in which he uses to sheath his sword).

In BoBoiBoy Galaxy, his outfit was changed into light blue coat with amber lines and black trousers, with navy blue gloves and red belt with yellow lines and some pockets. His mask is now colored gray with blue eyelines. There's a TAPOPS badge on the right arm of the coat. He still has the scar on his left cheek that he got from the battle at the final episode of the original series.

~ Lieutenant Lahap describe Captain Kaizo "between friend or foe"

Captain Kaizo is a very proud, extremely serious, mysterious and a sarcastic individual. To reach his goal, he is willing to do anything to achieve it, even if it requires violence. According to Fang and Lieutenant Lahap (Kaizo's loyal sidekick), he is one of most dangerous and strongest alien in space, proved that he got the title as "Legendary Space Rebel", he was able to easily defeat Ejo jo, rumored over since he fought with the Tengkotak leader, Bora Ra and also has very powerful powers and abilities, especially from his ergokinesis.

Kaizo and Fang relationship

Even known as a rebel, Kaizo is very calculated and honorable. This has proved that he challenged BoBoiBoy to have fought with him to prove that he is worthy to had got his power band or not. After their battle and loss, he accepted his defeat and believed that BoBoiBoy and his co. are worth to get a power band. He wanted to recruit BoBoiBoy and the others to join his team. But since his way is too extreme to resolve his missions, they refuse to join his side besides his goal actually good. Kaizo didn't force their decision even it's his own brother's decision to choose stay with BoBoiBoy instead of returning to his team. He also warned to them that there is another alien that will come to earth before his departure, which it later to be the Tengkotak.

Although Kaizo is quite cold and indifferent to the people around him, he can still show affection to his younger brother, best shown in Kaizo's pet name for Fang, 'Pang'. Kaizo's affection for his brother was showed yet again when he gave up his shield to protect his brother and risked himself from getting hurt himself when he tried to save him from Jugglenaut


Captain Kaizo commands to Private Pang (Fang) to search a power band at Rintis Island, he told to him to keep his true identity by giving a false name, and to use violence if it is necessary. He decides to leave him alone and state that Fang needs more time to search and observe it, and he will return in the right time.

Later on, he is seen talking with Bago go and witnesses Ejo jo who escape in the Bago go hospital. He finally returns to earth with his partner named, Lieutenant Lahap, defeat Ejo jo and his robot, P.E.T.A.I who wanted to revenge from BoBoiBoy. He introduces and reveals himself, and also reveals Fang's true identity was a Alien. We wanted to take a power band from him and his co. , but they refuse to give it. Kaizo tells to Private Pang to destroy them, but he is unable to do it and state that he is BoBoiBoy's friends and that they will never have a fight after their clash. Lahap is very furious to hear Private Pang's statement but Kaizo calms him down and he decides to finish him with his own.

After his battle with BoBoiBoy Thunderstrom, he begins to lose his interest to have a fight with them and order Lahap to eliminate them with dangerous toxic from his bag. Shocking with Kaizo decision, Private Pang stop at them and stole his friends power band and give it to Kaizo, persuade to him to forget about them. Kaizo applause with his decision and accept his apology.

He return to his spaceship along with Fang and Lahap.No longer after that, he was chased by BoBoiBoy and co. who decide to retake the power band and save Fang with Adu du and Probe help. Kaizo welcomed them, and challenge at them to fight with him, which BoBoiBoy accept it. He finally defeated by BoBoiBoy and Fang, and honorary accept his loses. He later let BoBoiBoy and co. to take their power band and accept Fang decision to stay with them instead him. Before his departure, he warned at them about the other aliens who will attacking earth and drop them back to Rintis island.

Power and Abilities

Captain Kaizo main power was a energy manipulation, thanks to a mask that he wear. When he use it, he able to manipulated the energy with any form like a shield, energy sword, energy punch and many others. His energy shield and barrier know is very powerful and difficult to destroy it. Aside this, he also display some natural abilities like swordsmanship ,agility ,durability and flexibility. This shown how he very easy to  dodging and counter-attacking BoBoiBoy Thunderstorm's attacks, and still able to stand up after being thrown away by Fang and BoBoiBoy's golem combo attack.

In BoBoiBoy Galaxy, he also have second tier of his ability which called as "Amber Mask". In this stage, his energy change into amber-colored, become more powerful than the previous stage

His weakness is he can only focus his energy on one to three techniques at a time. This is shown when he concentrated large quantity of energy force into his sword, so large that the Energy Handcuffs and Shield were disarmed. It is unknown why Kaizo didn't activate this form from the beginning, but Fang's reaction implies that it has a possible weakness.


Why would I follow my brother? He’s already strong. I would need to take care of... huh?
~ Fang's comment about Kaizo

Fang/Private Pang is Kaizo former follower and Little Brother. They have good relationship even both of them shown more look like commander-private relationship rather than normal sibling, but Kaizo never mistreat him even he said and shown that he willing to punish or attack Fang if he disobey his order or feeling betrayed. Fang shown very loyal toward him and also toward his friends, which causing Fang didn't want to see Kaizo and Lahap eliminate his friends, and taken their power band so Kaizo and Lahap didn't attack them. When Fang decide to choose stay with his friends instead return to his team, he didn't force him and agree with his decision.

Their relationship also shown again at BoBoiBoy Galaxy. Even though Kaizo arrogantly told to him do not intervene his battle against Jugglenaut, its shown his warned actually he doesn't want everyone especially Fang getting hurt by Jugglenaut.
