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 appeared again in Season 3, Episode 24 with a more major role. He showed up with his spaceship to easily defeat his rival and his P.E.T.A.I. robots with the help of his alien, 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.

Physical Appearance
In a concept photo first released by Animonsta, Captain Kaizo has dark blue hair, brown eyes and light skin. His attire is mainly coloured orange, dark grey and dark blue. The orange jacket he wears is edged dark blue with a high collar, dark blue shoulder attachments and a dark grey pattern that extends from his shoulders to about half way down his sleeve. His jacket is worn open and he has a black shirt underneath. His yellow belt has a hexagonal buckle and a dark blue covering. On his head, he wears what looks like a helmet and earpiece (this later turns out to be a mask) coloured various shades of grey with light orange streaks in the crevices. He also wears gloves that are similar to Fang's.

In his official series appearances, his outfit has changed dramatically, particularly the colours. His spiky hair is now dark purple, very much like his brother's, and his eyes are changed to having a reddish hue. He also wears dark blue fingerless gloves in a similar fashion to  Fang. The high-collared jacket he wears is now mostly blue in colour with ultramarine colouring the parts where his shoulders are all the way to nearly reaching the elbows. There also seems to be metal plates decorating the shoulders of the jacket. The turtleneck shirt Kaizo wears underneath the open jacket is ultramarine as well. 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). His pants are the same ultramarine as his shirt, and the same blue fabric of his jacket seems to decorate and cover most of the upper half of his pants.
