Blue Fangs (ブルーファングス Burū Fangusu?) is a minor antagonist in the Netflix original series, Castlevania. He was a demon in Dracula's army who killed the Bishop. It was later slain by Trevor Belmont and Sypha Belnades.
Blue Fangs was a powerful demon that led the night horde in purging Gresit. Despite his appearance, Blue Fangs is highly intelligent. He possesses a strong vocabulary and understanding of morality. He seems to fully understand his own evil nature and hates hypocrisy, shown in the joy he took in breaking the Bishop's false self-righteousness before eating him. In battle, though, Blue Fangs is a feral butcher, delighting in tearing humans apart with his fangs and claws.
- Blue Fangs is likely based on the Warg enemy from the games.
- In the French version, he is simply called "Demon".
- While he may have been lying to the Bishop in order to break his mind, Blue Fangs does seem to possess some understanding of the Bible, as he remarked that burning people accused of witchcraft made God sick.
