Appearances of the concept throughout the series
- In Haunted Castle, a large portrait of a woman (presumably of Selena) in Stage 3 will shed a tear of blood as the player passes by. This was probably the first time the concept appeared in the series.
- Carmilla's mask is often seen crying tears of blood from its left eye (or eye socket) in many of its appearances throughout the series, starting from Castlevania II: Simon's Quest, which in some occasions are used as a form of attack.
- In Castlevania Chronicles, a giant statue of the goddess Athena in Stage 4 constantly sheds tears of blood; each time a drop touches the ground, it will transform into an indestructible Red Skeleton.
- Statues of saints (presumably of Virgin Mary) can be seen crying tears of blood on the hallways of Castle Proserpina in Castlevania: Bloodlines.
- In a cutscene of Castlevania (N64) and Castlevania: Legacy of Darkness, the statue of an angel starts shedding copious tears of blood as the player approaches it. From the puddle that forms on the floor a new enemy then emerges: the Blood Jelly.
- In Castlevania: Aria of Sorrow, an item was introduced called the "Tear of Blood" which raises several stats.
- One of Medusa's attacks in Castlevania: Lament of Innocence is to shed tears of poisoned blood.
- One of Wind's quests in Castlevania: Portrait of Ruin is called "The Statue's Tear" and consists in asking the player to find a statue of Virgin Mary in one of the portraits. When the player interacts with said statue, it will shed tears of blood and an item called the "Statue's Tear" will be obtained, which must then be brought back to Wind. The reward for completing this quest is Jonathan's Holy Water skill.
- The Game Over screen for Sisters Mode displays an image of a woman (presumably Virgin Mary) crying tears of blood, possibly referencing this quest.
- In Castlevania: Lords of Shadow, Zobek says: "Poor, beautiful Carmilla, you will cry bloody tears before this night has ended!" before Gabriel fights Carmilla in the Throne Room.
- In the Castlevania animated series, Dracula is seen shedding tears of blood when he grieves his wife Lisa's death.
- The concept of religious imagery weeping tears of blood or presenting stigmata —believed to originate from supernatural means— are widely-known phenomena often associated with divine miracles, especially in Catholic beliefs.
- The name of this theme could be a reference to the classic Hammer "Dracula" horror films, where Count Dracula (portrayed by Christopher Lee) is sometimes seen crying tears of blood.
- The introductory segment in Bloody Tears bears an uncanny resemblance to the 1985 song "Marching Out" by renown heavy metal guitarist Yngwie J. Malmsteen. The song predates the release of Castlevania II: Simon's Quest by two years, making both products relatively contemporary. Konami is well known for making numerous references to rock music in their games.
- There is a common misconception that the Perfect Selection Dracula Battle version of Bloody Tears was performed by Gothic Metal band Cradle of Filth; however, this is not true, as it was arranged by Naoto Shibata.
