|First Appeared||F-Zero X|

F-Zero Legend of Falcon
Antonio Guster is a well-learned mechanic as well as infamously-known explosive specialist. He once worked alongside Samurai Goroh in his crew of intergalactic bandits, being Goroh's most trusted assistant on their many heists and bounties. All of that however changed when Goroh abandoned Guster after catching a recent bounty and taking all of the money and credit for the job while Guster was left for the Galactic Space Federation's arrest(to make this matter even worse, Guster just happens to be the younger brother of Lisa Brilliant!). After eventually escaping his prison at the aid of allied inmates, Guster vowed revenge against Goroh for his betrayal and entered the F-Zero Grand Prix with his own custom-built machine, the Green Panther, as a result. He thereby planned to ultimately win first place and put Goroh to shame on a worldwide scale!
 F-Zero X
In the second console-based installment of the F-Zero franchise, Antonio Guster was introduced for the very first time. His Green Panther and overall appearance remained the same save the fact that his helmet was a bright red rather than a solid, soft blue.
 F-Zero GX
In the most recent console-based title, Antonio Guster returns with his current placeholder appearance complete with blue helmet and the same scorned ambition to get even with Samurai Goroh once and for all. At least 85% of the answers he gives in the F-Zero TV interviews relate to his grudge against Goroh and the revenge he plans for his ex-ally.
 F-Zero GP Legend
While he has no playable storymode missions of his own in this game, Antonio Guster does show up in some of the available characters' storymode missions at one point, mainly Samurai Goroh's after Goroh found out it was really Guster who intentionally poisoned him and confronts him on it.
 F-Zero Climax
Due to the lack of an actual storyline, besides being based off of the finale to F-Zero Falcon Legend(character-wise), Antonio Guster makes it into the franchise's second Game Boy Advance installment with enhanced grip, boost, and noticably weakened overall speed.
 F-Zero Legend of Falcon
The plot involving Antonio Guster and Samurai Goroh's hate for each other is depicted differently in the anime. Rather than Goroh abandoning Guster in the middle of a bounty, Goroh kicks Guster out of his group of thieves for his out-of-control habits that he brings upon the crew during each heist, which usually involves planted explosives and a great big mess to clean up. Bitter towards the outcome, Guster sets off on his own and is eventually enlisted by Zoda of Dark Million in regards to his outstanding knowledge of explosive weaponery which Black Shadow finds will come in handy for his venture of intergalactic conquest.
