Aranaut, Various episodes

Aranaut (アーナウト, Ānauto?) is a Haos knight/ninja-like Bakugan from Neathia. He is Fabia Sheen's Partner Bakugan in Bakugan: Gundalian Invaders and previously was the Partner Bakugan of her fiancé, Jin. He becomes Captain Elright's Partner Bakugan in Bakugan: Mechtanium Surge.


Aranaut partners with Fabia of the Bakugan Battle Brawlers. His whole body sparkles like platinum. A skilled fighter, with abilities that are balanced between attacks, defense skills, speed and reflexes. Aranaut is equipped with a unique ability to emit an electromagnetic field from both his hands.[1]

Bakugan: Ultimate Handbook[edit]

What's that shining in the sky? A rocket? No, it's Aranaut, with a body that sparkles like platinum.

Some Bakugan are strong in one area, like attacks, but weak in other areas, like speed. Not Aranaut. His skills are evenly balanced between attacks, defense skills, speed, and reflexes. That makes him a good match for almost any kind of opponent.

When Aranaut does attack, he emits an electromagnetic field from his hands to paralyze foes.[2]


Bakugan Battle Brawlers: New Vestroia[edit]

Aranaut first appears along with Coredem, Hawktor, and Akwimos when they show up in Bakugan Interspace. He then battles alongside an avatar version of Baron created by Bakugan Interspace against the real Baron and Saint Nemus. He then manages to defeat Baron after combining with the Battle Gear Battle Crusher.[3]

Bakugan: Gundalian Invaders[edit]

His digital clone appeared, but Jake chose Coredem's clone over Aranaut.[4]

The real Aranaut is used by Fabia to fight Helix Dragonoid. Fabia also used the Battle Gear known as Battle Crusher, which was seen in a previously. In the end, Fabia and Aranaut failed to defeat Dan to bring him on the Neathian side, so she teleported off to a corner in Bakugan Interspace where Aranaut asks Fabia if they should return home, but she refuses to go back empty handed. Then Shun appears and asks Fabia for her side of the story.[5]

Aranaut used Battle Crusher to fight Plitheon alongside Fabia, but lost due to a bug in the arena that Ren set up for Drago.[6]

He and Fabia speak with the Brawlers while they are searching for Marucho about the true facts. They were similar to what Ren said to the Brawlers prior and also mentioned that his digital clone sent back a message to him after it was defeated and informed Fabia about a strong Bakugan (Helix Dragonoid) that could help Neathia.[7]

He was introduced to Dan's mother like the rest of the Neathian Bakugan and Fabia. Later, Fabia and Avatar Marucho battled against Lena and Zenet to stall for time while Marucho hacked Bakugan Interspace. Avatar Marucho used the digital clone of Aranaut to battle but the two Aranaut's eventually fallen. The battle caused the real Aranaut to become drained, almost trapping him and Fabia in Bakugan Interspace until Marucho and Akwimos showed up.[8]

He battles Lumagrowl, but they are interrupted by the Sacred Orb, which transports the Gundalians and the hypnotized children back to Gundalia.[9]

He battles Plitheon and Lythirus, alongside Hawktor. He manages to beat Plitheon mostly and later they won.[10]

He and Coredem battled against Plitheon and Linehalt. Plitheon beat them both in the first round, but Coredem and Aranaut took the second and third ones.[11]

He and Akwimos battled against Sabator and Linehalt. However, the battle was undecided due to the Sacred Orb's dimensional twister.[12]

He battled Koji, who had an Impalaton, alongside Drago and Raytheus.[13]

He battled Strikeflier; it seemed like he won until Lumagrowl came in and used Barias Gear. He wasn't able to beat him, and lost to Lumagrowl in the succeeding episode.[14]

It is revealed that he used to belong to Fabia's fiancé, Jin, but was captured by Kazarina and taken to her lab. However, Fabia snuck in to her lab and rescued him, as he is her last link to Jin. Aranaut, however, lost his memory of this event and believes he has always been Fabia's partner. Later in the episode, he defeats Linehalt and Rubanoid in a battle to prove Ren's loyalty.[15]

Aranaut and Sabator fought Lumagrowl and Lythirus. The two were doing fine until Lythirus used an ability that flooded the whole arena. He managed to rescue Fabia from the strong current but unfortunately couldn't do the same for Nurzak and Sabator.[16]

He took Fabia throughout the Gundalian castle.[17]

He revealed he never forgot about Jin and he was lying the whole time because Fabia was so grief-stricken over Jin's death.[18]

He battles Lumagrowl, Krakix, Strikeflier, and Lythirus alongside Hawktor, Akwimos, Linehalt, Coredem, and Blitz Dragonoid. They are victorious, but he and Fabia stay behind to fight Kazarina.[19]

He continues to battle Lumagrowl with some help from Mason and Avior. At the sight of Kazarina's dead body, Lumagrowl is shocked, causing him to be defeated. The two Bakugan realize that this must have been their fate and Aranaut watches Lumagrowl run off.[20]

He returns to Neathia with Fabia, Mason, Avior, Nurzak, and Sabator. They are held up by Gill and Krakix, but manage to hold them off long enough for to get away. On Neathia, he battles an army of Gundalian Bakugan and defeats them, only to be blasted into submission by Phantom Dharak.[21]

He is later woken up by Linehalt's forbidden power and says goodbye to the humans and Gundalians before he teleports the Humans back to Earth.[22]

Bakugan: Mechtanium Surge[edit]

Aranaut reappeared in Gundalia Under Fire, where he and other Neathian Bakugan went to Gundalia to help the Gundalians in their fight against Mag Mel and his Chaos Bakugan alongside his new Mobile Assault, Rapilator.
