Sonic Lanterns: Ghost the Rainbow Serpent
Ghost is the seventh child both to Hydra the Dragon and Adalinda of the House of Mythos, making him the younger brother of Garnett the Phoenix, Umber the Black Dog, Sapphire the Kelpie, Payne the Griffin, Sepia the Satyr, and Shamrock the Tree Nymph, the older brother of Pine the Yeti and Azure the Dragon as well as the nephew of Azreal the Dragon. As a member of the Mythos bloodline, Ghost was gifted with the power to control the element of light. He was born mute and although he can communicate through sign language and code through flashing lights, he often chooses not to and keeps many of his thoughts to himself. He witnessed Garnett burning Shamrock alive as means to keep Sapphire, and anyone else, from leaving like Azure had. Like Pine, Ghost is one of the few of their siblings who is incredibly loyal to Garnett.
Ghost appeared briefly at the end of chapter 1 of Hostile Encounters alongside his brother Garnett and Pine as they arrived outside Azreal's hut. On Garnett's orders, they decided to wait until Azure would return the next day before capturing her. Though Azure begged him and Pine not to do this, the ignored her pleas and knocked her unconscious before taking her back to the Mythsetia Veil.
During Garnett's prophecy, Ghost willing took part before it was stopped by the combined efforts of Azreal the Dragon, Raphaella the Ocelot and Shadow the Hedgehog. When Umber successfully subdued Garnett and exiled him from the island, he offered Pine and Ghost the chance to stay, but not if they remained loyal to Garnett. On Garnett's orders, Ghost let out a burst of light, temporarily blinding everyone and giving the three brothers time to escape.
Ghost will appear in Rise of the Titans as a member of Team Garnett.
A future version of Ghost is mentioned by Z as leading a small group of survivors through Crisis City along with Sepia and Payne.
