Aranaut (アーナウト, Ānauto?) is a Haos knight/ninja-like Bakugan from Neathia. He is Fabia Sheen's Guardian Bakugan in Bakugan: Gundalian Invaders and previously was the Guardian Bakugan of her fiancé, Jin. He becomes Captain Elright's Guardian Bakugan in Bakugan: Mechtanium Surge.
Aranaut is partners with Fabia of the Bakugan Battle Brawlers. He is incredibly loyal to Fabia and the Castle Knights, often noting that he will defeat his opponents in the name of the Castle Knights when he stands. His whole body sparkles like platinum. He is a skilled fighter with offensive abilities, defensive skills, speed, and reflexes. He is shown to be a gentleman, such as when he met Dan's mom in episode 9. He is also equipped with a unique ability to emit an electromagnetic field from his hands. His Battle Gear is Battle Crusher.
Aranaut first appears in Phantom Data Attack 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.
The real Aranaut is used by Fabia in The Visitor 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.
In True Colours, 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.
In Escape From Darkness, 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.
In The Secret Switch, he battles Plitheon and Lythirus, alongside Hawktor. He manages to beat Plitheon mostly and later they won.
In The Secret of the Orb, he and Akwimos battled against Sabator and Linehalt. However, the battle was undecided due to the Sacred Orb's dimensional twister.
In Forgiveness, 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 into 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.
In Redemption, he and Sabator fought Lumagrowl and Lythirus. The two were doing fine until Lythirius 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.
In Final Strike, he took Fabia throughout the Gundalian castle.
In Dream Escape, he revealed he never forgot about Jin and he was lying the whole time because Fabia was so grief-stricken over Jin's death.
In Gundalian Showdown, 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.
In Broken Spell, 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 runoff.
In Code Eve, 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 to get away. On Neathia, he battles an army of Gundalian Bakugan and defeats them, only to be blasted into submission by Phantom Dharak.
In Destiny Revealed, he is woken up by Linehalt's forbidden power and says goodbye to the humans and Gundalians before he teleports the Humans back to Earth.
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.
