Aurora

Allegedly the most powerful deity of Mobius (although Sonic the Hedgehog #163 implied that her might may be inferior to that of the Ancient Walkers) and the Chaos Force, Aurora's appearance depends on who views her. Because the only characters that have encountered her so far are Knuckles and Athair, she has only appeared before as a female Echidna. Aurora appears to Knuckles in the afterlife, after he sacrifices himself to save Dimitri. She shows him visions of his life, which prompts him to leave the afterlife and return home. She also helps him return to his normal red hue, as opposed to the green he would have had for some time.

Later, Aurora would prove more selective about her intervention: she is fully willing to get involved in her own affairs, but the rest of the time leaves Mobius hanging. Being a deity, she has untold knowledge, including the fact that Knuckles was worthy of a second chance at life. (It should be noted that Knuckles was revived, not reincarnated; in essence, Aurora found Knuckles worthy of coming back to life in the same body that he had died in, at the same age, instead of being reborn as somebody entirely different.)

When Knuckles visited his father's grave during the events of Mobius: 25 Years Later, Locke and Aurora were seen looking down on him as he made the decision to let Lara-Su become a Guardian.

Mammoth Mogul revealed that the Order of Ixis, which he founded, was decimated during the "Forgotten War" with the Albion Knights of Aurora. This organization was named for Aurora, and in their efficient efforts left only Mogul and the three sorcerers who would become Ixis Naugus.

Aurora is an echidna with pink fur and blue eyes, his abilities are most likely anything and everything - dream making, shapeshifting, ressurrection, and travel between planes of existance are shown, and his weakness is that he doesn't fully understand mortal nature.
