Sonic Universe IDW

Current appearance
Sonic looked about 28 years old, not 16. His fur was azure, his quills fluffier, his eyes emerald as always, his hands were covered with black gloves with a blue middle finger, over which the fabric was pulled, and the other hand had the same. He also wore blue leg warmers, black half-boots with an azure-blue ribbon and a small heel, and a black scarf with a blue stripe at the ends. He was forever stuck at the age of 28, unable to age or rejuvenate. After a glitch in his forms, his fur darkened, the positive energy (which he always used) became unstable, and his Super and Hyper Forms disappeared forever, replaced by a Dark Form (Hyper - Phase 3, Super - Phase 1, without Phase 2).

Personality at the moment
He doesn't understand anything, he's scared and tired. His memory is slightly damaged temporarily, causing dissonance. Unlike the Master Emerald and Chaos, he doesn't know that his clothes have changed, that his fur has changed, that he's gotten older, and that the positive energy now feels more like negative energy.

Kind and caring, he is very grateful to Chaos, Knuckles, and Sonic for protecting him. He is attached to Sonic and is willing to do anything to protect or save him. He was a Lesser God but then made a grave mistake that led to the extinction of Ancient Mobius and its inhabitants, and was forcibly turned to stone for it. He also bears a slight grudge against the Elder and Middle Gods for killing his girlfriend as punishment for his misdeeds.

The Master Emerald wields power over the seven Chaos Emeralds and can manipulate their energies, both neutralizing and enhancing them. With godlike powers and a limitless supply of energy, it can greatly enhance both living beings and robots. For example, in the case of Sonic's Mark II, the Master Emerald enabled a brief transformation into a super form. It also serves as a powerful power source for various machines and combat mechs, including such colossal constructs as the Death Egg. The relic can be used to seal away beings, both divine and mortal, likely resulting in the death of the latter. Its power is so great that it can distort reality: shifting entire islands through time and restoring a planet divided into different regions using Chaos Control. Since the Master Emerald exists simultaneously in all timelines, its disappearance from one would trigger a chain reaction, resulting in its disappearance from all others.
The Master Emerald is sentient and conscious: it can project three-dimensional images, allowing it to communicate with others. When a threat related to the Chaos Emeralds emerges, the Master Emerald can suddenly appear at the most unexpected moment. Only those who maintain close contact with the relic—specifically, members of the Knuckles Clan, such as Tikal and Knuckles himself—can fully utilize its power. To unlock and utilize its abilities, they typically need to recite a Prayer. The Master Emerald can also communicate verbally, engaging in dialogue and monologues.

The deity turned to stone

The Master Emerald (Masutā Emerarudo) is an object in the Sonic the Hedgehog series. It is a stone of incredible power and the only force in the universe capable of suppressing the energy of the Chaos Emeralds.[1] The Master Emerald rests on Angel Island, usually located in the Emerald Altar. Its power keeps the island afloat, as without it, the island would fall.[1]

Information
The Master Emerald is a green, diamond-cut gemstone. While typically massive, it can be resized at the will of its keeper, down to the size of a palm.[2] The emerald possesses immense energy, comparable to that of a large Chaos Emerald.[3] It is considered one of the most powerful relics on Earth. In terms of power, the Master Emerald is second only to the Phantom Ruby (Ruby is also a deity that possesses an alt-form of the stone, and the Phantom Ruby is a Middle God, while the Master Emerald is a Lesser God).

Personality
Chaos is said to have a warm heart. The God himself is, above all, a very loving and gentle being who cares for all the Chao he protects. Chaos only becomes active in times of danger and attacks only when a Chao needs protection, at which point he can be overcome by uncontrollable rage.

After an attack on his territory several thousand years ago, Chaos was corrupted by his own negative emotions, causing him to abandon his peaceful and passive ways and become a rage-filled monster, driven only by his own immeasurable anger. His rage was so great that he wanted nothing more than to destroy the world, but he later became kind again. He loves Sonic very much, cares for him, and worries about him.

Powers and abilities
Chaos is an incredibly powerful being, so powerful that it is revered as a deity. Even the weakest form of Chaos is said to possess immeasurable powers.

Chaos has the ability to absorb Chaos Emeralds, and his form, strength, and abilities change and increase with each emerald he absorbs. Being composed of liquid energy, Chaos is also virtually indestructible and can mimic the properties of water. He has complete control over his physical structure, allowing him to perform limited shape-shifting, such as extending his limbs, transforming himself into liquid, and if he dissipates, he can reform again.

Deity

Chaos (Japanese: Kaosu) is a character in the Sonic the Hedgehog series and the main antagonist of Sonic Adventure. He is an immortal, godlike being composed entirely of concentrated energy. Essentially, he is the Guardian God of all Chao and their friends. Chaos has the ability to change form with each Chaos Emerald he absorbs.

Appearance
It is a lifeform with a body composed of pure energy, similar to water. The forms it can assume are numerous, though its most recognizable form is its Chaos 0 state. In this state, it possesses a humanoid form with disproportionately long arms and legs compared to its torso. It has thick hands with three thumbs on each hand, a short stump for a tail, and long legs with two thumbs on each. It also has two fin-like protrusions on the back of its head, sharp hairs on each side of its head, and a high bulge on the crown of its head. It also has no facial features, save for two pupil-less, lime-green eyes. Finally, inside its transparent head, it has a round pink brain, with a brain stem at the bottom.
