Changes

Early into the season, it is revealed that he is the long-lost {{nihongo|'''Keith Fermin'''|キース・フェルミン|Kīsu Ferumin}},<ref>''[[Beta City Blues]]''</ref> the older brother of [[Mira Fermin]] and the son of [[Clay Fermin]], the Vexos' lead researcher. His pursuit for power and obsession with creating the strongest Bakugan, a vision he shared with Helios, put him at odds with not only the [[Bakugan Battle Brawlers Resistance|Resistance]] that Mira led, but eventually with the rest of the Vexos themselves. At the end of the season's first arc, he is labeled a traitor by others, causing him and his loyal aide, [[Gus Grav]], to become free agents. Though the two continue to clash with the Resistance, they eventually become allies as they fight their common enemy, [[Zenoheld]].

Spectra appears in the video game ''[[Bakugan: Defenders of the Core]]'' in his ''New Vestroia'' persona, serving as the game's main antagonist.

Spectra removed his mask and outer coat, happily reuniting with his sister [[Mira]] and reverting to the name of his original persona, [[Keith Fermin]]. It was also revealed that Keith had begun to miss his partner [[Gus Grav]], and how Keith had obtained his [[Battle Gear]] was found out. Keith decided to get [[Dan and Drago]] a [[Battle Gear]], but to do so, he needed to engage Dan in battle again in order to test if the [[Battle Gear]] in question was right for Drago's body. He put his mask on once more, becoming Spectra yet again. He then challenged [[Dan and Drago]] in [[Bakugan Interspace]], finalizing [[JetKor]] as Drago's [[Battle Gear]].

Despite the Brawlers' plan to leave in the early morning to defeat [[King Zenoheld]] once and for all, Keith left on his own and challenged the King himself in the guise of Spectra, later with the help of [[Gus Grav]], whom Spectra was shocked to see alive. [[Zenoheld]] also revealed the [[Alternative]] Weapon before the end of the battle. At that time, the Bakugan [[Resistance]] arrived, and they will attempt to destroy the [[Alternative]] with the help of Keith and Gus. As the fight continued, Keith and his sister Mira managed to find a way into the [[Alternative]] by blasting a hole into it via Keith's [[Helios MK2]] and his new [[Battle Gear]], [[Zukanator]]. They found their father, who wished to protect his creation. When the others [[Resistance]] members managed to destroy the power reactor of the [[Alternative]], they also managed to escape, but [[Clay Fermin|Professor Clay]] was trapped behind and left behind when he saved [[Mira]] from being crushed by falling debris. The group reluctantly returned to the [[Vestal Destroyer]] as the [[Alternative]] blew up with [[Clay Fermin|Professor Clay]], [[Prince Hydron]] and [[King Zenoheld]] either inside or within the explosion's range.

===Bakugan: Mechtanium Surge===

In ''[[A Hero Returns]]'', [[Zenthon]] appears but [[Drago]] couldn't control him and, because of that, attacks all the Brawlers' Bakugan, included [[Infinity Helios]]. Spectra seems disappointed and sad about Dan's attitude and leaves the interior of the [[Bakugan Interspace]].
