Ariadne is an optional boss making her debut in Phoenotopia Awakening. She is the queen of the Cave Beetle clan and can be found deep within Mul Cavern. She appears to be able to climb on walls and summon Cave Beetles to aid her.
- The game's creator states that he created Ariadne because he felt the last stretch of the game felt too long and uneventful without one more boss in between.
- He also admitted that she was made to be one of the game's tougher bosses, possibly the second-toughest boss in the game.
- Ariadne is named after the Greek mythological figure Ariadne, who is the daughter of King Minos and also sometimes considered a goddess of weaving.
