Sonic and the Secret Rings
The Blue Ma Djinns first appeared in Sonic and the Secret Rings. They originate from multiple places, but all share the common characteristic of being driven to madness during the events of the game. Some appear to have been regular inhabitants, others were evil spirits sealed away long ago by King Solomon, and the rest were created by the Erazor Djinn from carving up the words of the Arabian Nights. Regardless, they were all recruited into Erazor's personal army and used to attack the world of the Arabian Nights in his search for the World Rings.

The Blue Ma Djinns are some of the most common enemies in the game and can be found in every World. In gameplay, they have no attack and remain in the spot they appear in, though they can still inflict damage should the player touch them. They can be defeated with a single hit, and when they are, they release Pearls.
