==Information==In {{Nihongo|''Battle Planet'' and 'Nillious'Armored Alliance'', Nillious was |ニリアス|Niriasu}} is a bipedal multiple-headed hydra/dragon-like [[Bakugan with two heads - ]] from the left with one hornreboot series, and the right with two horns. Part-way into debuting in ''Geogan Rising[[Bakugan Battle Planet]]'' A [[Nillious (Magnus Black)|Darkus variant]] appears in the anime, however, being the design only-one-of Nillious was changed significantly, giving him a third head with three horns and adding an additional pair of legs, changing his body plan to be more reminiscent of a centaur. Initially, instead of traditional draconic wings, Nillious had mechanical wings with turbines inside of them - this was changed in ''Armored Alliance''its-kind, and kept into ''Geogan Rising''. Despite thisowned by [[Magnus Black]], some as well as being the main rival of Nillious' attacks are still seen emerging from where the turbines once were[[Drago (Dan Kouzo)|Dragonoid]].

The double headed Nillious main motive in brawls is to kill - not to win. He does not like fighting as a team with his partner, Nillious is out satisfy only himself. He likes to go rogue. Each head has own personality and ability. Untamable and vicious Magnus has his hands full keeping Nillious in line.<ref>[https://web.archive.org/web/20220127211045/https://bakugan.com/en/bakulog Nillious' BakuLog entry]</ref> ===Appearance===In ''Battle Planet'' it appears as a two-headed hydra/dragon with mechanical wings. Later on ''[[Armored Alliance]]'' has a more organic aspect, with natural dragon wings instead of mechanical ones.<br/>In ''[[Geogan Rising]]'' becames a three-headed hydra/dragon/centaur; and then, into an Elemental Bakugan on ''[[Evolutions]]''.<br/>''[[Bakugan: Legends]]'' reverted the changes made to Nillious, changing him back into a two-headed bipedal Bakugan for his Nova form; however, his Nova Strength form retains the third head and centaur body design.

===''[[Bakugan Battle Planet]]''Major Appearances===Nillious joins Magnus in his attempt to turn the [[Awesome Ones]]' new Bakugan against them, a [[Darkus (Reboot)|Darkus]] Bakugan named [[Artulean]]. After Magnus' plan works and he reveals his disguise, Nillious brawls [[Lightning]] and [[Howlkor Ultra]], but after the rest of the Awesome Ones return, Magnus flees riding on Nillious.<ref>''[[Dog Daze]]''</ref> ===''[[Bakugan: Armored Alliance]]''=== ===''[[Bakugan: Geogan Rising]]''=== ===''[[Small Brawl Stories]]''==={{Non-Canon}}In ''[[Tin Pan Alley]]'', while Drago is practicing his abilities on paper targets, [[Nillious]] hides behind one of the targets and surprises Drago by attacking with [[Shadow Breath]] and [[Darkus Blast]]. To expose Nillious, Drago uses [[Back Draft]] to incinerate the target.<ref>''[[Tin Pan Alley]]''</ref> In ''[[Teamwork Makes the Dream Work]]'', Nillious attempts to taunt [[Dragonoid (RebootMagnus Black)|Drago]] into a brawl as Drago, [[Cyndeous]], and [[Gorthion]] watch up. Instead of listening to Drago's advice and staying hidden, Gorthion steps out and uses [[Drum Wave]], but Nillious uses [[Reflection]] and sends the wave back at Gorthion, incapacitating him. After the failed attempt by Gorthion, Cyndeous steps in and uses [[Volcanic Lance]] against Nillious, but misses and is taken out by [[Shadow Breath]]. Drago then appears, and uses [[Guard Sphere]] to trap Nillious in a bubble, leaving him unable to attack further.<ref>''[[Teamwork Makes the Dream Work]]''</ref> {{-}}==Evolutions=====''Battle Planet''===<tabber>Hyper Nova Mode={{BBP Bakugan Infobox|name = Hyper Nillious Nova Mode|image = [[File:BBP-Hyper Nillious Nova Mode anime.png|250px]]|attribute = Darkus|power = 800}}{{Nihongo|'''Hyper Nillious Nova Mode'''|ハイパーニリアス・ノヴァモード|Haipā Niriasu Novua Mōdo}} He is the attack mode of Hyper only Nillious in ''[[Bakugan Battle Planet]]''.|-|Hyper Shadow Mode={{BBP Bakugan Infobox|name = Hyper Nillious Shadow Mode|image = [[File:BBP-Hyper Nillious Shadow Mode anime.png|250px]]|attribute = Darkus|power = 800}}{{Nihongo|'''Hyper Nillious Shadow Mode'''|ハイパーニリアス・シャドーモード|Haipā Niriasu Shadō Mōdo}} is species that appears on the defense mode of Hyper Nillious in ''[[Bakugan Battle Planet]]''.|-|Titan Nova={{BBP Bakugan Infobox|name = Titan Nillious Nova|image = [[File:BBP-Ultima Nillious Nova anime.png|250px]]|attribute = Darkus|power = 1000}}'''Titan Nillious Nova''', {{Nihongo|'''Ultima Nillious Nova'''|アルティマニリアスノヴァ|Arutima Niriasu Novua}} in show; and its the Japanese version, is the second evolved form of Nillious that splits into its own entity in ''[[Partner Bakugan Battle Planet]]''.|-|Titan Shadow={{BBP Bakugan Infobox|name = Titan Nillious Shadow|image = [[File:BBP-Ultima Nillious Shadow anime.png|250px]]|attribute = Darkus|power = 1000}}'''Titan Nillious Shadow''', {{Nihongo|'''Ultima Nillious Shadow'''|アルティマニリアスシャドー|Arutima Niriasu Shadō}} in the Japanese version, is the second evolved form of Nillious that splits into its own entity in ''[[Bakugan Battle Planet]]''.</tabber>{{-}} ===''Evolutions''===<tabber>Strength Mode={{BBP Main Bakugan Infobox|name = Nillious Strength Mode|image = [[File:???.png|250px]]|attribute = Darkus|power = 800}}'''Nillious Strength Mode''' is an Elemental Evolved Form of Nillious in ''Bakugan: Evolutions''.
