The Captain inhabits the central quarters of the Ghost Ship. As the player enters the room, the painting will suddenly come to life and begin to spin and bash violently around. If the painting manages to make contact with the player, a painted portrait of either him or her will appear on its canvas and the now free spirit of the Captain will break it apart, resulting in an instant death.
Upon being vanquished, the portrait –after uttering an otherworldly wail– will have its frame shatter, followed by the canvas burning apart.
- An explanation for this enemy's behavior could be that the spirit of the Captain is trapped within the painting and when he manages to make contact with the player, both switch places and the evil spirit is then free to roam around while now it's the hero the one who will remain trapped in it for eternity. That's would also be the reason why the Captain destroys the portrait afterward - to both ensure to permanently defeat the hero and also to prevent the possibility of the painting ever trap him again.
- In Castlevania: Portrait of Ruin, Brauner, one of the main antagonists of the game, uses a similar attack during his boss fight, where he enters a painting canvas which then floats and swoops around the room, much like the Captain from Rondo of Blood, attempting to bump on the player to deal considerable damage.
