The Master Emerald Power[]
The Master Emerald is regarded as the most powerful gem in the Universe, possessing unbound and infinite power even more powerful than the Chaos Emeralds. As its primary function, the Master Emerald has the power to fully control everything that the Chaos Emeralds do, which grants it the ability to both negate and empower Chaos Emeralds, meaning it can stop the Chaos Energy of the Chaos Emeralds, or enhance them. The Master Emerald's energies can as well be harnessed to initiate a super transformation(Mecha Sonic)
The Master Emerald has also been seen creating three-dimensional holographicimages within itself (thus suggesting that the Master Emerald is in fact sentient). In addition, if the Master Emerald is broken into several pieces, it can repair itself if the shards are brought back together. However, the shattering of the emerald seems to give the shards an explosive trajectory, causing them to fly a great distance which makes the task of gathering them rather painstaking.
As revealed in Sonic Rivals, the Master Emerald is a transcendental object that exists simultaneously in all time lines across the time-space continuum(Omnipresent).
Only Knuckles, Chaos and Tikal are able to talk to, command, and control the Master Emerald
