Unlike previous Castlevania titles, Dracula's Curse introduces the ability to recruit up to three allies to aid Trevor C. Belmont. Each ally possesses unique abilities and weaknesses, making character selection a strategic decision throughout your playthrough. You can only have one ally with you at a time, and you can switch between Trevor and your current ally using the Select button.
- Trevor C. Belmont: The main protagonist. Wields the Vampire Killer whip, which can be upgraded. He has balanced stats and is generally the most versatile character. His sub-weapons are the standard Castlevania fare.
- Sypha Belnades: A powerful sorceress. She has low physical attack but excels in magic, casting devastating spells like fire, ice, and lightning. Her spells consume hearts rapidly but can clear screens of enemies. She is vulnerable to physical attacks.
- Grant Danasty: A nimble pirate. Grant can climb walls and ceilings, offering unparalleled mobility. His dagger attack is quick but short-ranged. He is excellent for navigating tricky platforming sections and finding hidden areas.
- Alucard: Dracula's son, a half-vampire. Alucard can transform into a bat, allowing him to fly over obstacles and enemies. His projectile attack is strong but slow. He is a powerful character but his bat form consumes hearts.
Choosing the right ally for the right situation is key to success. For example, Grant can bypass many platforming challenges, while Sypha can make short work of bosses with her magic.
