Aldebaran holds the mantle of Taurus Gold Saint within the Sanctuary's hierarchy. Hailing from Brazil, he stands as the physically strongest Gold Saint of his generation, a heritage that significantly boosted his popularity within his home country due to the rarity of Brazilian characters in anime. His demeanor is generally amiable and approachable, often laughing and displaying a less formal attitude during peaceful times compared to his fellow Saints, contrasting sharply with his formidable combat power. He shares a close friendship with Aries Mu and respects the determination of young warriors like Pegasus Seiya. Aldebaran possesses strong independent judgment; initially following the Pope's orders, he grows skeptical after witnessing the conviction of the Bronze Saints during their assault on the Twelve Temples. Honoring a pre-battle promise, he permits Seiya and his companions to pass through the Taurus Temple after Seiya breaks one horn of his helmet. He acknowledges he could have effortlessly eliminated the Bronze Saints but chose not to, recognizing the sincerity of their cause. During the Sanctuary arc, Aldebaran tests the Bronze Saints at his temple. His signature battle stance involves crossed arms, allowing him to unleash his "Great Horn" technique at light speed for simultaneous offense and defense. After Seiya awakens his Seventh Sense and damages the helmet, Aldebaran allows passage. He later confides his doubts about the Pope's integrity to Mu, solidifying his allegiance to Athena. In the non-canonical Asgard arc, Aldebaran is ambushed by the God Warrior Mizar Syd (later revealed to be executed by Syd's brother, Alcor Bud). Surviving the attack, he relays crucial tactical information about the assailants to Silver Saint Shaina. Facing Marina General Siren Sorrento in the Poseidon arc, Aldebaran's strength is drastically reduced to 1% by Sorrento's auditory attacks. In a desperate countermeasure, he ruptures his own eardrums to nullify the music, though this proves insufficient. He ultimately uses his cosmos to immobilize Sorrento temporarily. This self-inflicted deafness later contributes to his vulnerability. At the start of the Hades conflict, Specter Nyx's Deep Niobe kills Aldebaran as he guards the Taurus Temple. His deafness prevented him from detecting the Specter's approach. Even in death, his lingering cosmos aids Mu in overcoming Nyx's Deep Fragrance technique. Aldebaran's spirit joins the collective sacrifice of the twelve Gold Saints to destroy the Wailing Wall in the Underworld, demonstrating unwavering loyalty to Athena beyond death. His spirit later reappears in "Next Dimension" to support Athena's efforts in the past. In the spin-off "Saint Seiya: The Lost Canvas," set in the 18th century, the Taurus Gold Saint bears the inherited title Aldebaran, with the given name Rasgado. He mentors three trainees, emphasizing protection of the weak and strength beyond the battlefield. Rasgado engages in a fierce battle against Specter Bennu Kagaho, sustaining severe injuries including the loss of his right eye. Despite the cost, he emerges victorious by channeling "Titan's Nova," motivated by duty to his students. He later participates in strategic discussions with Sagittarius Sisyphus and the Grand Pope regarding the Holy War. The "Episode G" spin-off depicts Aldebaran as easygoing with a fondness for collecting mementos. He assists allies like Leo Aiolia and Capricorn Shura against Titans, utilizing "Great Horn" to defeat mythical beasts such as the Hydra. His resilience proves pivotal in divine battles, where he withstands overwhelming assaults to create openings for comrades. Aldebaran's primary technique is "Great Horn," executed through two distinct methods: a rapid, defensive-counteroffensive strike from his crossed-arms stance, and a more powerful offensive blast requiring focused cosmos projection. Mastery of the Seventh Sense grants him light-speed movement and full cosmic energy control. While not formally educated, his training imbues him with extensive knowledge of astronomy, mythology, and human physiology for combat. The name "Aldebaran," derived from the brightest star in the Taurus constellation, represents a legacy title bestowed upon the most formidable Taurus Gold Saints across generations in various spin-offs and timelines.
