Straizo
Straizo is the Hamon master who betrays the Joestar lineage across Battle Tendency — a Phantom Blood-era Ripple practitioner who survived into the 1930s and then chose Stone-Mask vampirism over his own mortality. Originally one of Will Anthonio Zeppeli's Hamon brothers and one of three Phantom Blood characters to live into the Battle Tendency era (alongside Erina Joestar and Speedwagon), Straizo's vampire conversion is one of the franchise's most-cited Hamon-master-corruption sequences. He is killed by Joseph Joestar in the early Battle Tendency arc.
Story
Phantom Blood & Battle Tendency
Part 1 · 1843–1939Straizo's pre-Battle-Tendency biography is depicted across both Phantom Blood and Battle Tendency. Born in 1843 in northern Italy, he trains as a Hamon practitioner under Tonpetty alongside Dire and Will Anthonio Zeppeli — the four constitute the Phantom Blood-era Hamon master-school. Straizo participates in Will Zeppeli's Phantom Blood Windknight's Lot Hamon training of Jonathan Joestar and survives the campaign as one of three Phantom Blood characters to live into the Battle Tendency era.
His betrayal of the Joestar lineage arrives in 1938. Straizo, now 95 years old and facing the end of his natural life, encounters the dormant Pillar Man Santana and recognises the Stone-Mask's vampire-induction mechanism as a path to extended life. He chooses Stone-Mask vampire conversion over Hamon-mediated natural-aging acceptance — killing George Joestar II (Joseph's father) in the process as a structural argument that vampire-coded immortality requires moral compromise. His combat scene against Joseph Joestar in the early Battle Tendency arc resolves with Straizo's Hamon-still-extant-but-vampire-augmented body being defeated by Joseph's tactical Ripple-improvisation. Straizo dies repenting the betrayal in his final moments — one of the franchise's most-cited deathbed-redemption sequences.
Powers & Abilities
Sendō Ripple (Vampire-Augmented)
HamonStraizo's combat capability is unique across the franchise — he is the only depicted character to wield both Hamon and Stone-Mask vampirism simultaneously. His pre-vampire-conversion Hamon training under Tonpetty gives him the franchise's most-extended Ripple-mastery (nearly a century of practice from his teen years through his 1938 conversion), and his post-conversion vampire biology augments the Hamon output with regenerative-and-strength enhancements.
The hybrid mechanic is structurally unstable — Hamon energy is biologically incompatible with vampire physiology, and Straizo's body must constantly suppress the Hamon's vampire-counter-attack effect on his own tissue. The mechanic has been read by long-form JoJo critics as Araki's deliberate articulation that hybrid power-system combat produces ongoing structural cost rather than purely additive advantage. Signature attacks include Vampiric Hair Strike (vampire-augmented Hamon-charged hair projection) and Space Ripper Stingy Eyes (the vampire pupil-projection technique he inherits from Dio Brando's combat lineage).

Trivia
- Straizo is one of three Phantom Blood characters to live into Battle Tendency — alongside Erina Joestar and Robert E. O. Speedwagon. His extended survival across nearly a century of in-universe time makes him the franchise's longest-lived Hamon practitioner from the Phantom Blood-era school.
- His Battle Tendency betrayal arc is the franchise's most-cited Hamon-master-corruption sequence — a Ripple practitioner who has spent his life opposing the Stone Mask voluntarily converts to vampirism. The mechanic has been read by long-form JoJo critics as Araki's deliberate articulation that ideological-and-moral commitments can collapse under the pressure of mortality.
- Straizo is the only depicted character to wield both Hamon and Stone-Mask vampirism simultaneously. The hybrid mechanic is structurally unstable and produces ongoing combat cost rather than purely additive advantage — the franchise's clearest articulation of hybrid power-system limitations across the entire saga.
- His deathbed-repentance after Joseph's combat victory is one of the franchise's most-cited deathbed-redemption sequences. The mechanic — villain-aligned character recognises moral failure in his final moments — is the structural template for several later franchise deathbed-redemption character beats.
