Ancients

The Ancients (古代人 Kodaijin?) are a race that appear in the Sonic the Hedgehog series. They were very advanced aliens that existed in prehistoric times. They were originally from an alien planet and took refuge on Earth after being attacked by a mysterious entity that destroyed their home planet. They reached the Starfall Islands and settled there. Their settlement on the island did not last long, however, as a threat to destroy their planet followed them, and they fled towards what is now known as Angel Island. However, the Ancients were wiped off the face of the Earth by unknown circumstances, leaving only their creations on the Starfall Islands and Angel Island.

Anatomy
Ancients share many similar traits with Chaos 0, and are long-bodied humanoid creatures that appear to be made of some kind of energy. They have claw-like hands, with three fingers on each hand and two fingers on each foot. It has one ridge on the top of its head, two long ridges usually on the back of the head, usually from the shoulders and waist, and two glowing eyes. Ancients exhibit sexual dimorphism; for Males they have a masculine torso and upturned shoulder and hip protuberances, while females have a long occipital protuberance, a feminine torso with dropped shoulders, and thin, drooping shoulder and hip protuberances. Ancients are similar to regular male ancients, except that they have prominent eyebrows and prominent shoulders and hips. Child Ancients are smaller and shorter, with a much shorter head protrusion and no shoulder and hip protrusion. The ancients tended to slouch. The protrusion on the head extends in a zigzag pattern and drags it down. The shoulder and hip protrusions are also dragged down a little. Additionally, elders appear to have a prominent vascular system on the surface of their bodies.

The Ancients usually don't wear clothes. However, they contain cocos in their torso as some sort of good luck charm or source of life.

History
Since prehistoric times, Ancients have lived on planets far from Earth. One day, a mysterious entity known as The End threatened the Ancients and their planet. To attempt an escape, the Ancient built a machine called Chaos His Engine, which harnesses the power of Chaos His Emerald to power a spaceship and escape. From impending doom.

Once successful, they board a spaceship and escape while witnessing an explosion on their home planet. During their travels, they approach planet Earth, and the Chaos Emeralds on board begin to react to the Master Emeralds on Earth. As a result, the ancients lost their ships and the emeralds pulled them to earth. The ancients land on the Starfall Islands and begin rebuilding civilization from there. Among these creations were altars powered by Chaos Emerald energy, and cyberspace that stored all the hopes, dreams, memories, and data of the ancients and was accessible through portals they created. They also created weapons, towers, and an army of robots to defend themselves should The End reach Earth.

Trivia

 * The Ancients may have been hinted as early as Team Sonic Racing in 2019, with carvings at the end of the Sky Road track showing heads that resemble that of Chaos and/or what seems to be an Ancient.
 * The Ancients share their name and many characteristics with the group from the Sonic Boom series.
 * The Ancients are known as "los Ancestros" (the Ancestors) in the Spanish dub of Sonic Frontiers. This dub change also acts as foreshadowing, as is later revealed that they are the ancestors of Chaos.
 * According to Ian Flynn, the Ancients, that piloted the Titans, had placeholder names in the script of Sonic Frontiers in order to identify and differentiate the four of them.
