Moonwatcher

Moonwatcher was the son of Guardian Steppenwolf and the second of the Guardians to possess a link to the Chaos Emeralds of Angel Island. Working as a team with his father, Moonwatcher protected the Echidnas for many years. Moonwatcher was the first Guardian to be brought to Haven by his father, where the two would rotate their duties of protecting Echidnaopolis. He became a member of the original Brotherhood of Guardians along with his son Harlan, the name of the group having been conceived by his grandson Remembrandt. Not much is known about Moonwatcher's tenor as Guardian except that he defeated the Dark Legion during one of their many breakouts of the Twilight Zone, sending them back to their imprisonment.

Dying at some point of either old age or other causes, he would appear at Kncukles the Echidna's funeral along with the other deceased Guardians, and mistook Chao messengers from Aurora as arriving to guide his father to the Chaos Force.
 * Moonwatcher's uniform slightly resembles that of the Starfleet attire from Star Trek. Additionally, with his visor, Moonwatcher is very similar in appearance to Star Trek: The Next Generation character Geordi La Forge.
