Narcissus is an optional boss added in Revelations Chapter One and can be found in the Mirror Room in the Glacier. He is one of Revelation's bosses that is not based on a base-game boss. Narcissus is a special boss that works into Revelations' story. The whole boss fight is symbolic, and also quite literal, of fighting one's reflection. Narcissus will always drop Mirror Shard when defeated, which will work its way into subsequently released Revelations' chapters (like how Key Piece 1 and Key Piece 2 work). Revelations adds in Health Scaling for their added bosses. Narcissus' health will be set at the beginning of the fight dependent on whichever number is higher between 200 or the player's damage times 20.

  • Narcissus is made out of mirrors and is a representation of a reflection of Isaac.
  • Narcissus makes use of Active Items extensively, morphed into versions that are harmful to Isaac.
  • According to the code, Narcissus' name was originally "Narciccus."
  • Early in development, Narcissus was called "Corinthian", a reference to 1st Corinthians 13:12 in the Bible, which talks about mirrors
    • For now we see only a reflection as in a mirror; then we shall see face to face. Now I know in part; then I shall know fully, even as I am fully known. (1st Corinthians 13:12)
  • According to the game files, the Narcissus boss fight was either supposed to be entirely of Isaac using the same attacks, or Phase 1 being able to use the same attacks (see Gallery).
  • In Greek Mythology, Narcissus was a hunter from Thespiae, son of river god Cephissus, who was well known for his beauty. Narcissus was so proud of his beauty, that he brushed off those who loved him, for he thought they weren't worthy of him. Nemesis, who enacted punishments to those who showed arrogance to the gods, noticed this, and lured Narcissus to a pool of water. Seeing his reflection, Narcissus fell in love with himself, not realizing that it was a mere image. Unable to look away from his beauty, Narcissus lost the will to live and stared at his reflection until he died. (Info taken from this page).
    • This story is also the origin of the word narcissism, which is described as "excessive or erotic interest in oneself and one's physical appearance."
  • The difficulty of the boss and his later counterpart is likely based on how the player must shatter a mirror door to access him. Shattering mirrors is believed to be a bad omen.
