{{nihongo|'''Gus Grav'''|ガス・グラヴ|Gasu Guravu}} is the right-hand man of [[Spectra Phantom]] and a former member of the [[Vexos]] organization, until he and his master Spectra betrayed them and been labelled as traitors. He is a [[Subterra]] Brawler and is powerful in battle. He used [[Hexados]] as a Trap Bakugan and teamed up with the Subterra [[Rex Vulcan]]. He was presumed to have died while battling against [[King Zenoheld]]. In episode 42, Spectra states that Gus disappeared without a trace, but in episode 49, however, Gus was shown in a prison cell along with Hydron. He tricked Hydron into helping him escape to join Spectra in the final battle against Zenoheld. He and Vulcan later fought in the final battle against [[Mag Mel]].

Once the Resistance and the [[Vexos]] make it back to [[New Vestroia]], Gus keeps a close watch on Mira, as he doesn't trust her. Once the brawlers get to [[Gamma City]], [[Dan Kuso|Dan]], and [[Ace]] face often against Gus and Mira. Spectra beforehand had Gus and Mira take the Bakugan that were being developed for [[Prince Hydron]] to test for himself. However, due to Mira purposely throwing the match, Gus and Mira lose, all six of the Bakugan are captured, and the last [[Dimension Controller]] is destroyed.

==TriviaTrading Card Game==*Gus is the only Subterra Brawler seen to battle head-on and win against [[Dan Kuso]] in a brawl.*{{Gus Grav is similar in appearance to Hikaru Hazama's mother in ''Beyblade: Metal Fusion Series''.*Gus also strongly resembles Tobias from ''Pokemon DP: Sinnoh League Victors''.*He also reassembles Pierce from Pokémon the Series:Black and White.*He has another similarity [[w:c:inazuma-eleven:Shindou Takuto|Shindou Takuto]] from ''Inazuma Eleven GO''.*[[Mason Brown]] sounds like him at times despite the fact that they have different voice actors.*Gus's outfit color changed throughout the series. At first it was dark orange and later, it was light orange.*In episode 33, on the intermission screen, Gus and Alto Brontes appeared as Gus was using him in the battle with Volt. However, the Subterra attribute symbol was highlighted despite the fact Alto Brontes was a Haos Bakugan. This is most likely because Gus mainly uses the Subterra attribute.*Despite joining the Brawlers, he is not featured in the Japanese Special Ending of episode 52.*He is referred to as Spectra's "lap dog" since he's so loyal to Spectra, and calls him "Master".*In the Japanese version of the 2nd episode of New Vestroia; Mira referred to Gus as "The Greatest Subterra Battler, the Desert Wolf Gus Grav. '''サブテラ最強のバトラ 砂漠の狼 ガス・グラヴ''' (''Sabutera Saikyou no Battora, Sabaku no Ookami Gasu Gurabu'').*Like Spectra, he changed his clothes in Mechtanium Surge. In New Vestroia, he had very light brown coat, and black, brown and white suit under it. In Mechtanium Surge, he had brown sweatshirt. *At first, Gus used "good", blue ability cards. When he joined Spectra, he changed them to red.Cardlog}}
