- For the version of this object before the Super Genesis Wave, see Air Necklace (Pre-Super Genesis Wave).
The Air Necklace consists of a gray necklace-styled oxygen bottle shaped like a handle. When worn, it releases a steady stream of oxygen, allowing its wearer to breathe safely in otherwise toxic atmospheres.
- The Air Necklace is based on the Level Up Item that appeared in Sonic Adventure 2 and Sonic Adventure 2: Battle.
