Nelvana Enterprises produced an English version which aired on the Canadian television network Teletoon on July 8, 2007.

[3] In North America, eight DVD compilations were released by Nelvana in Canada and Sony Pictures Home Entertainment in the United States.

[5] The battle begins when the story of how the game of bakugan was created with the help of Dan Kuso and many other children, and how it quickly became popular around the world.

The battle continues with Marucho barely managing to win with the pop idols element combination working against him.

Shun's grandfather attempts to attack them but Runo and Marucho accidentally pull out their Battle Cards and stop time.

Alice Gehabich is worried about telling Runo about her grandfather being Hal-G, the human who corrupted Naga's mind.

He gets home and sees that his grandfather left him a message stating that "things are gonna change under my house rules."

When all the Brawlers, minus Julie, get there they find a video recording from Dr. Micheal that explains how bakugan entered the human world and how he was involved in that.

The brawlers have settled down to eat dinner but no one except Dan seems to have an appetite as they are concerned about Julie who returned home depressed after the battle.

It then switches to the brawlers as they return to Marucho's plane as another day of searching for the infinity core and a door to Vestroia ends in failure.

Surprisingly, Dan opens his Gate Card at the same time as Runo, Marucho and Julio and is dragged into the battle.

The episode starts with the brawlers realizing that Naga has not yet reached the level of Ultimate Evolution as he is still trapped within the Silent Core.

Billy also tells them that Masquerade had shown him, Klaus, Chan, Julio, and Komba Naga who used the negative energy to brainwash them.

Shun remains quiet throughout this and later leaves the team as he feels none of them will be able to beat Masquerade — Dan and Runo always quarrel, Marucho moans over the loss of Preyas.

Dan, Runo, and Marucho are able to take down the remainder of Klaus, Chan and Julio's bakugan until only Sirenoid, Foretress and Tentaclear remain.

Just as their conversation stops the ground begins to shake and when they go outside they see Marucho's plane with Dan yelling 'I'm home!'

At the same time Shun receives a challenge letter from Masquerade and he and Skyress come up with a plan to find Dan and Drago.

The six bakugan introduce themselves as Pyrus Apollonir, Haos Lars Lion, Aquos Frasch, Subterra Clayf, Ventus Oberus and Darkus Exceedra.

When the brawlers demand to know what the ancients what they explain that they are searching for new warriors to save Vestroia from total destruction.

But there is a condition, the brawlers must face the ancient warrior of their attribute in battle...and win or else they will remain in the Doom Dimension forever.

The brawlers agree but Dan adds to the stakes saying that if they win all of the bakugan trapped in the Doom Dimension will be freed.

The ancients agree then in a flash of light they separate the brawlers sending them in different directions with julie and Gorem being the first to be tested.

Joe reveals that he and Wavern defeated Masquerade thanks to the vast positive energy and power of the Infinity Core.

After that, all the Brawlers minus Alice are over at Dan's watching the news reports about all the strange weather occurring around the world, then out of the blue Joe is challenged by Masquerade to a battle for control of the Infinity Core.

Klaus flies Alice to the Vestroia portal, where as she jumps and skydives toward it, she summons Masquerade's mask and transforms into him one last time to get his support to help Dan and Drago.

Naga's ultimate goal is to capture Wavern and to take the Infinity Core and with the Brawlers out of the picture, it looks like he will succeed.

Battlers from all over the world, including top brawlers Chan Lee, Klaus Von Herzon, Billy Gilbert, Komba O'Charlie, and Julio Santana, answer Joe's message and with their Bakugan, go on the offensive against Naga and his team.

Dan is informed that Hairadee, Centorrior and Druman are also approaching the city following Tayghen's death and Tricloid's defeat.

With the power of all six attributes, Drago overwhelms Naga and destroys him, releasing the Silent Core and absorbing it.

After the group shares a tearful farewell, Drago opens a portal to Vestroia, allowing all Bakugan to begin their journey home.
