Bakugan: Mechtanium Surge
Jaakor made his first appearance in Evil Arrival as Shun's latest partner. He battled Drago in the Bakugan Tournament and resulted in a horrible defeat. Later, as Mechtavius Destroyer was formed, he and Radizen aided Drago, only to be later knocked out by the fierce Destroyer.
In Wiseman Cometh, the mysterious brawler named Wiseman appeared, and Jaakor aided in the battle against him. Dan and Drago were forced to summon Dragonoid Destroyer, so that Reptak and Jaakor could launch a jumping attack at Mechtavius Destroyer.
In The Prodigal Bakugan, Jaakor is seen training with Shun to learn how to overcome his weaknesses during a battle. After the training session, it is revealed that Jaakor has two friends, Skytruss and Orbeum, in Bakugan City. They both want Jaakor to leave with them because of Wiseman and their distrust for humans. After meditating on this and talking to Shun, he decides to leave with them. However, when he feels that Shun was in trouble, he goes back and helps him fight Wiseman and his Bakugan. He is easily able to handle them, but when the two Bakugan fused together, Jaakor was overwhelmed by their strength, even with Orbeum and Skytruss's assistance. Jaakor fused with his students to become Magmafury, and defeated the fused Bakugan. Jaakor would stay with Shun as he sees his two students take off to protect the other Bakugan on New Vestoria.
In Combination Impossible, he is with Shun and the other Brawlers discussing his battle with Wiseman and his Bakugan. He and Drago get on Radizen's case about when he will he be able do a combination with another Bakugan, which causes Radizen to leave the room.
In Enemy Allies, he battles some of Wiseman's Bakugan and was doing well until Mechtavius Destroyer was summoned and took out Dan and Drago. Orbeum and Skytruss were summoned and they became Magmafury but even that wasn't enough to stop Mechtavius Destroyer. Runo then gave Shun a new Battle Suit, Fortatron. With it, Jaakor was able to block Mechtavius Destroyer's attack and create an opening for the Brawlers to exploit for them to defeat Mechtavius Destroyer.
In Gunz Blazing, Shun summoned him to battle Wiseman but it turned out that the Brawlers were tricked by a Wiseman hologram.
In Countdown to Doomsday, he appears again to battle Wiseman but loses against Mechtavius Destroyer.
In Evil Evolution, he fought against Mechtavius Destroyer and combined with Skytruss and Orbeum, alongside Duomechtra and Betakor, but lost and was banished to the Doom Dimension alongside Dan and the other Brawlers after Gunz arrived with the Nonets.
In Blast From the Past, he and the Brawlers locate Mechtavius Destroyer on the volcano island.
In Beginning of the End, he and the Brawlers fought against Mechtavius Destroyer. He combined with Skyruss and Orbeum to form Magmafury but was defeated easily. However, Jaakor rejoined the fight, but with Fortatron, and summoned Thorak.
In End of the Line, he was seen watching Dragonoid Destroyer defeat Mechtavius Destroyer alongside the other Brawlers.
