Julio Santana (ジュリオ・サンタナ, Jurio santana?) is a character in Bakugan Battle Brawlers.



Bakugan Battle Brawlers

Julio is a Haos battler and his Guardian Bakugan is Haos Tentaclear. Julio was the fourth ranked Bakugan player until Masquerade defeated him. He is presumed to live somewhere in Europe. He is also shown to have a strong rivalry with Runo for being the best Haos brawler. He also sometimes gets called "Q-Ball" by Runo.

Julio, along with other Top Brawlers in the world comes to a "party" created by Masquerade, it is there where he is sent to the Silent Core and put under the control of Naga. When Julio is under the control of Naga, he fights against Runo and Dan, and ends up losing although he sends four of their Bakugan to the Doom Dimension. After that defeat, he fights Dan, Runo and Marucho in one final battle alongside Chan Lee and Klaus von Hertzon, but loses again and is freed from Naga's control. Julio is next seen when Masquerade defeats him and sends Tentaclear, along with 2 of his other Bakugan, to the Doom Dimension off-screen.

He chooses to stall Tricloid when Naga's minions invade Earth. He reappears to help the Brawlers fight Naga's forces when he battles Hairadee alongside Komba and Shun.

Later he joins Klaus Marucho Julie and Billy to battle Centorrior and Druman along with Dan and Runo. They easily take them down. When Naga is beaten he is crying when he has to let Tentaclear go.

Bakugan Battle Brawlers: New Vestroia

In Duel in the Dunes, Julio briefly appears in the group picture taken back in Season 1 shown by Dan.


Julio is currently ranked 9th.

  • His appearance is somewhat similar to Sid Arkale from Gundalian Invaders and Ben from Mechtanium Surge. Even their Japanese voice actors are the same.
  • Of all the five top ranking brawlers controlled by Masquerade, he is the only one who is seen setting his Doom Card upon his first battle against the Brawlers. Billy and Komba set it off-screen, while Chan and Klaus never actually set it in their first battles, which is an error.
