Wisp simply appears as a pale purple ball of flame. Wisp is mute and cannot speak, only able to communicate by growing brighter or dimmer, similar to how light spirits communicate.
Wisp maintains a sibling rivalry-like bond with Cygnus and is very loyal to Odette.

- Heat manipulation: Wisp can generate, absorb and manipulate heat.
- Flame resistance: Wisp is completely resistant and immune to fire.

- Levitation: Wisp is capable of hovering in the air.
- Faint Wisp: Wisp can become fully intangible at will.
