Rubanoid (Japanese version Rubianoid (ルビアノイド, Rubianoido?)) is a ruby coated dragon-like Bakugan. He was used by Sid Arkale, but then entrusted to Ren after Sid passed away. His Battle Gear is Destrakon Gear. Ren then went on to give it to Linus Claude as his new Guardian Bakugan after the loss of Neo Ziperator.

He, like other Gundalian Bakugan, have a great hatred of Drago, which lasted up until the final events of Bakugan: Gundalian Invaders.


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

Bakugan: Gundalian Invaders

He first appeared being used Sid Arkale and was equipped with Destrakon Gear battling Helix Dragonoid and Akwimos tagging with Phosphos He can talk, meaning that he is in fact 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 tagging with Avior to fight Venoclaw and Buz Hornix. He attacks Buz Hornix using Jewel Thevor while Avior took Venoclaw out using Bolting chain. Later he fought alongside Buz Hornix against Coredem and Akwimos. He sits most of the battle out but joins when Buz Hornix had a rock thrown on him. Sid puts on Destrakon Gear on him and uses his battle gear ablity. Buz Hornix uses queen riot causing his opponets damage. Jake Vallory opens up Darkus battle audence causing Coredem an Akwimos to become darkus. Akwimos uses heal blue to heal up him and coredem then punches Buz Hornix knocking him out. Jake puts Rock Hammer on Cordem while Marucho puts Gigarth on Akiwmos. Sid opens up ruby storm to give him an advantage. He uses his battle gear leval 2 ablity and has his foes down for the count. Coredem and Akwimos use their battle gear abblties causing him and Sid to lose, 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 evolving into Lumino Dragonoid, back in Gundalia after Emperor Barodius dismissed Sid, Rubanoid was furious saying that their loyalty and services demands respect, but was knocked out and beaten by Krakix attacking him from behind 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. After escaping he battles alongside Ren and Linehalt against Dan and Lumino Dragonoid. but all Bakugan ended up losing round 1 to due the battle gear hitting each other. In the second round Dan brought out Jakalier for Drago to use causing him and Linehalt to pull out there battle gear. Drago than departed and used his battle gear. The attacks all hit but him and Linehalt lost despite it being 2 on 1. 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]

He appeared healing himself in a special tank with Linus as he was badly damaged by Aranaut's Battle Crusher attack in his last battle under Ren's ownership.[8]

In the final events of Gundalian Invaders, Linus and him team up to help fight the Gundalians with him battling a hypnotized Contestir. He loses and later battles Plitheon, Phosphos, Contestir and many Gundalian Bakugan alongside Raptorix and Neathian Bakugan. When the Brawlers arrive, he says "A couple minutes earlier would've been helpful!"

  • Rubanoid is the only Bakugan to appear as translucent in the anime.
  • Like Phosphos, his name sounds similar to an element on the Periodic Table of Elements, Rubidium.
  • Strangely, he and Viper Helios have the same attack action on Bakugan Dimensions.
  • Along with Aranaut, he is the only Bakugan that had three owners.
    • Coincidentally, both of their first brawlers are deceased and the second one gave it to a Castle Knight.
  • Had him and Sid not escaped from Kazarina's lab they would have been brainwashed by her.
