Ivan, designated Troll Ivan, holds the title Divine Defeating Star among Hades' 108 Spectres. His Troll Surplice draws inspiration from Norse mythology, representing the brutish, magically skilled, and physically unattractive trolls, traditional adversaries of the Nordic gods. The Slavic name Ivan, derivative of John, means "graced by God." Renowned for formidable physical strength and hand-to-hand combat prowess, Ivan ranks among Hades' strongest Spectres. He guards the Third Prison of the Underworld. During the invasion by Bronze Saints Cygnus Hyoga and Dragon Shiryu, Ivan confronts them but underestimates their strength. As he declares, "I won't let you pass through the third prison, for I am...", Hyoga interrupts with the absolute zero Diamond Dust technique, freezing Ivan instantly. His final words, "For I am...Ivan of the Divine Defeating Star...", are uttered just before he collapses and dies. This swift defeat is underscored by his star's association with "defeat." In the spin-off *Saint Seiya: The Lost Canvas*, Ivan appears briefly as a bodyguard for Hades at the entrance to the Lost Canvas. The anime adaptation places him in Italy in this protective role, though his involvement remains minimal and receives no significant narrative expansion. Series creator Masami Kurumada conceived a technique for Ivan named "Greatest Perestroika," but it remains undepicted in both manga and anime adaptations. Canonical information provides no details on Ivan's personal history, motivations, or character evolution beyond his role as a Spectre. His narrative function is confined to the Third Prison encounter, with no substantive appearances or developments in other seasons, films, or spin-offs.
