He is suspicious and it seems as if he is going to betray Prince Hydron shown in Return of a Friend. In Unmasked, Mira's suspicions of Spectra prove to be true when he removes his mask and is, in fact, Mira's brother, Keith. In Brotherly Love, Viper Helios gets upgraded to Cyborg Helios. In Final Countdown, the Vexos ditched him and set the palace on self destruct mode. He managed to escape with the help of Gus Grav. In Spectra Rises, Cyborg Helios was upgraded to Helios MK2. He now is working to take the Perfect Core energy from Drago and take over all of Vestal. Spectra temporarily joined with the Brawlers after Gus' disappearance.

In Spectra Rises, he upgraded Vulcan to Rex Vulcan. After learning of the Vexos' plan to betray Spectra, Gus rescued Brontes and Elico (who were thrown out by Mylene Farrow) and saves him and Helios before the Vexos Motherpalace explodes. After feeling that his master was insulted by Zenoheld, Gus let his loyalty get to him as he challenged Zenoheld to a battle to defend Spectra's honor. Elico and Hexados sacrifice themselves to protect Gus and Vulcan, while the two stand and face Zenoheld's final attack together. He is presumed dead but is later revealed to have survived his battle with Zenoheld and has been imprisoned since.
