Ghost Rider's supernatural nature and soul attacks give him an edge over Doom's impressive but primarily physical defenses.
Doctor Doom is uniquely equipped to fight Ghost Rider thanks to his mastery of sorcery. Unlike most tech-based villains, Doom can engage on the mystical plane and potentially counter some of Ghost Rider's supernatural abilities. His magical shields may provide defense against hellfire that conventional armor cannot.
However, the Spirit of Vengeance operates at a divine/infernal level that exceeds most mortal sorcery. Ghost Rider's hellfire burns the soul, and even Doom's magical defenses have limits against supernatural fire. The Penance Stare is particularly threatening โ Doom has caused immense suffering throughout his career, and the Stare would force him to experience all of it.
Doom's tactical genius and preparation could potentially find ways to contain or redirect the Spirit of Vengeance. He has dealt with supernatural entities before. But in a standard encounter, Ghost Rider's immortality and soul-attacking abilities give him the edge over even Doom's formidable defenses.
Doctor Doom's sorcery lets him fight on the mystical plane, and his magical shields may resist hellfire. His genius for preparation means he could develop containment strategies specifically designed for supernatural entities.
Ghost Rider's hellfire and Penance Stare bypass physical and most magical defenses to attack the soul directly. Doom has caused enormous suffering, making the Stare devastating, and the Spirit of Vengeance cannot be permanently destroyed.
Ghost Rider edges this through supernatural attacks that even Doom's sorcery struggles to fully counter. Doom's magical knowledge keeps this competitive, but the Spirit of Vengeance's immortality and soul attacks tip the scales.
