Jin is a paled, slim young man of average height. He has black hair with a grey-white streak on the right side. He has red eyes and wears a black and purple suit outside of a white shirt and a grey vest. He wears a pair of maroon skinny jeans and dress shoes.

As a little child he used to wear a white t-shirt with red sleeves, khaki shorts, black socks and trainers. His hairstyle was almost the same.

In Danball Senki W, he wears jeans and a teal shirt to match his new LBX, Triton, with a black and purple vest over it. His hair also grows a little.

In WARS Jin wears a white t-shirt with black vest, gray pants and navy blue jacket. His hairstyle appears slightly different. He also has a silver pendant.


Kaido Jin is a prodigy with a high degree of knowledge in technology. He is distant from others and tends to be silent, but he enjoys playing with LBX. Because he was raised from the rich Kaido family, he has a very social polite manner towards people, friends and otherwise. After becoming friends with Ban Yamano, he becomes more open.

He then appears in Blue Cats Cafe, entering the Underground Vicidus Tournament. In episode 12, he competes in the first round of Angra Visdas and also defeats his opponent. He watches Ban’s battle against Gatou, and is shocked when Ban uses his missile to implode Gatou’s missiles back at him. He makes it to the quarterfinals where he battles Ami. Ami tries to surprise him with a quick attack, but Jin anticipates it and Emperor strikes down Kunoichi in one quick hit. Jin advances to the semi-finals where he faces off against Kazu.

In episode 13, Jin and Kazu battle. Hunter tries to snipe him, but Jin’s  fast movements allow Emperor to completely avoid every shot, He jumps down and strikes his mace into Hunter’s shoulder joints as he wins the match in 9.9 seconds.

Ban tricks him into getting Emperor in the air and uses Advance V-Mode to gain the upper hand in battle. Jin is shocked, but smiles even as Emperor’s health drops by 25 percent because now he can fight seriously. Jin speeds up Emperor’s movements in further, blinding Achilles with rapid fire attacks from all angles and  causing Ban to lose Advance V-Mode in the process. As the fight drags on, Jin uses his hissatsu function: Impact Kaiser to defeat Achilles. The energy and the eruption is so fierce that half of the diorama is engulfed in magma and Achilles is buried. Jin thinks he’s won but is surprised by Ban sharing victory and Achilles getting up from the rubble. The two are evenly matched, and him and Ban prepare their finishing moves. However, Jin’s CPU stops responding. His responses were so fast that they overloaded the connection between his quick manual control and Emperor. With Emperor unable to react, Ban wins the tournament. Jin walks off, but gives Ban the coordinates to where Professor Yamano is located to help find his father.

In episode 16,  Jin challenges Van to a rematch with his new LBX, the Emperor Mark 2. His butler blocks off Kazu’s attempts to escape by warning them that Jin could trip the alarm if he wanted to. Jin comments on his ensured victory now that his processor’s been updated and what happened at Artemis won’t happen again. When the Emperor Mark 2 and Achilles both use their finishers, they knock each other temporarily unconscious. Jin is shocked that he cannot seem to defeat Ban, even with a new computer processor. However, his grandfather’s henchmen come in his room to capture Ban and co, so Jin tells them to leave.
