The strong silent type. Along with Dan, Shun co-created the rules and regulations of Bakugan and is a master of the game. Shun is a loner, a boy of very few words, yet is willing to help his friends at every turn. He approaches the game like a Ninja warrior, very calculating. Shun uses the wind attributes in battle. Many fans like to pair him with Alice, although throughout the series he has shown tiny interest in Julie Makimoto.

Shun's outfit in Bakugan Battle Brawlers was a black shirt covered with a thin purple triangular-backed ending. He also had black pants with a brown zipper like designs on around them. His black hair consists of two layers. The first layer of hair is the front all one his forehead, and his second layer is the straight hair tied up with a ponytail. His light brown eyes are in an upset mood.

In Bakugan Battle Brawlers: New Vestroia, Shun's outfit consists of a fully black sweater-like turtleneck, gloves that reach to his elbows, black Vestal jeans that he stole along with the rest of the outfit from when he infiltrated the Vestals after he saved Ingram. He has black rubber boots that almost goes to his knees. He later wears a long green vest up to his knees with a belt on the side when its open. He when he is on Earth he wears black pants with a black shirt with green markings. Shun's hair is almost the same only the difference is that he cut off his ponytail and his hair is up to his neck.

In Bakugan: Gundalian Invaders, he wears a green ninja style shirt with purple and gold trimming, black pants, black wrist bands and purple and green boots.

In Bakugan: Mechtanium Surge, Shun sports a light green shirt under a white shirt with dark green trimming, a dark green choker, tan colored pants and light brown boots.

Shun is one of the calmest brawlers in the series. He rarely gets flustered or annoyed, and even when he is annoyed, he maintain's a cool voice (although he voices his displeasure). Shun is a lone wolf and always focuses in battles.

Shun Kazami lives in the province, and is a Ventus attribute player. He is also an aspiring ninja, receiving training from his grandfather. He is a loner, yet is willing to help his friends at all costs. Together with Dan Kuso, his best friend and childhood friend, he invented the gameplay for Bakugan. He had been the first ranked battler until Masquerade and his minions dominated the rankings, and because his grandfather didn't let him play, ending up in 6th place. After defeating Komba, he ends up fifth. Shun is currently in 3rd place.

His mother is really sick, and it was when she slipped into a coma that Shun gave up on Bakugan, mainly because his grandfather stated that since he has to take custody of Shun until his mother gets better, he can't play the game anymore and has to concentrate on his training. His grandfather lets him brawl again, though. Shun's mom eventually dies.

Shun, now 16, appears in Bakugan Battle Brawlers: New Vestroia with a new Bakugan, Ingram.

He is first mentioned when Dan complains about not being able to reach him. He makes a cameo debut after Marucho passes out from his battle against Mylene Pharaoh. We hear Mylene tell him that she doesn't want to keep losing to him, and asks him if he wants to join the Vexos. When he doesn't reply, she takes that as a no. Shun then leaves, leaving Mira to wonder if he was her brother.

Later, Shun reappears to aid Dan Kuso in his battle against Spectra Phantom and Gus Grav. He tells the Brawlers how he was in the mountains, practicing his ninja skills when a portal suddenly opened, sending him to New Vestroia. Soon he met Ingram when the Bakugan were being sucked up by the Vexos, and he saves her by grabbing onto her ball as she was being teleported. Ingram told him about the Vexos, and he agreed to help him save the Bakugan. When he noticed Dan's battle, Shun activates his Gauntlet and uses Ingram and Hylash to fly over to where Dan is and help's defeat Gus. Once Baron reveals that they've reached Alpha City, Shun tells them, that he was heading there to rescue Skyress, thinking she might be there. He becomes an offical member of the Resistance.

Shun is seen competing in a battle in Bakugan Interspace with the synthetic Ventus Hawktor as his partner. He battles Shuji in arena F-12. He is ranked the second best brawler in Bakugan Interspace, right between Dan and Marucho. Shun still seems to distrust Ren, much in the same way as Ace distrusted Keith Clay when he first joined the Brawlers.

When Fabia Sheen appears and battles Dan , Shun is the first to suspect that Ren's story about the Neathians attacking Gundalia is not true. After Dan defeats Fabia and she leaves, Shun finds her and asks for her side of the story.

After learning from Fabia what was really going on, he and Fabia work together to expose Ren for lying about the Gundalian-Neathian war saying that the Neathians invaded Gundalia when it was really the other way around. Ren flees which Shun says only proves their theory correct. Marucho yells at him and runs after Ren.

Shun reappears in Bakugan: Mechtanium Surge with Ventus Taylean. Shun is now 4th strongest Brawler in Bakugan Interspace, behind Dan, Anubias, and Sellon, respectively. However, this is due to him not battling as much as he used to - due to his ninja training. He is starting to get suspicious of what Dan and Drago are doing. Later, he is seen commenting on whether Drago and Zenthon are connecting - due to the timing.

He has figured out that Dan is hiding something but Dan keeps on making excuses. Later, during Dan's battle with Anubias - Shun and Marucho realize that Dan is holding Drago's power back and that is what he has been hiding but they do not know why. He will battle alongside Dan against Sellon and possibly Zenthon. In the preview, he also comments that things have been strange since they returned from Neathia and that if they do not figure out what to do with Dan and Drago's problems - the Brawlers could be destroyed for good.
