Rubanoid, Rubianoid (ルビアノイド, Rubianoido?) in the Japanese version, is a ruby-coated, dragon-like Bakugan. He plays a major role in Bakugan: Gundalian Invaders, where he was Sid Arkale's Guardian Bakugan before Sid's passing, and was entrusted to Ren Krawler until he became Linus Claude's new Guardian Bakugan after the death Neo Ziperator. His Battle Gear is Destrakon Gear.

He was a playable Bakugan in Bakugan Dimensions.


Crimson armor protects Rubanoid effectively from attacks. He shoots red energy waves from his mouth and attacks by shooting hard blades fast and mercilessly.

Bakugan Dimensions[edit]

Rubanoid attacks by shooting his hard claws out fast and mercilessly, and his crimson armor protects him effectively from opponent's attacks.[1]


Bakugan: Gundalian Invaders[edit]

He first appeared being used Sid Arkale and was equipped with Destrakon Gear. He can talk, meaning that he is infact a real Bakugan, and not mechanical.[2]

He appeared again fighting alongside Contestir against Linehalt and Drago. He and Sid won while Zenet and Contestir lost (Zenet sacrificed Contestir to take out Drago's JetKor).[3]

He appeared again, fighting alongside Buz Hornix against Coredem and Akwimos. He and Sid lost, but they told the brawlers their secret, which was to stall time so that Ren could kick the brawlers out of Bakugan Interspace and not allow anyone from the outside of Bakugan Interspace to come in except the Gundalians and their brainwashed human army.[4]

He appeared to face Drago and lost when Drago evolved after merging with the Element, back in Gundalia after Emperor Barodius dismissed Sid, Rubanoid was furious saying that their loyalty and services demands respect, but was knocked out by Krakix and Kazarina said that she could use him in her experiments before transporting him. He was transported to her lab for experiments.[5]

Sid, Lena, Jesse, and Zenet were shown to not be dead but trapped in Kazarina's Lab. Sid and Rubanoid were the only ones to escape. He then battles alongside Ren and Linehalt against Dan and Drago. After losing, he was given to Ren before Sid was disposed of.[6]

He was used by Ren to battle against Aranaut after Linehalt lost. He lost too, even though he used Destrakon Gear's Level 2 Class ability.[7]

In the final events of Gundalian Invaders, Linus and him team up to help fight the Gundalians. When the Brawlers arrive, he says "A couple minutes earlier would've been helpful!"

In the Japanese version, he appeared in a special tank with Linus because he was badly damaged by Aranaut's Battle Crusher attack in Forgiveness.[8]

He decides to stay on Neathia as a Castle Knight along with Linus Claude.[9]

  • Rubanoid is one of the two only non-Mechanical Bakugan illustrated with computer graphics. The other is Dragonoid Colossus.
  • In Bakugan Dimensions, he and Viper Helios had the same attack action.
  • Along with Aranaut, he is the only Bakugan to have three owners.
    • Coincidentally, both of their first brawlers are deceased and the second one gave it to a Castle Knight.


The "Rub-" prefix of his name is derived from the Latin word rubeo, which means "to be red." (The word "ruby," present in his Japanese name, is derived from the same Latin word.) The suffix -oid means "to bear a likeness to."
