マスターエメラルド
The large, green gemstone watched over by [[Knuckles the Echidna]]. Its power keeps his homeplace, Angel Island, afloat in the sky.
The God of Destruction, [[chaos_(sonic)|Chaos]], was sealed inside it along with [[tikal_the_echidna|Tikal]] following the destruction of the Knuckles Clan. The emerald has the power of cancelling the effect of the seven smaller [[chaos_emerald|Chaos Emeralds]]. If it shatters, Knuckles is capable of sensing its pieces and placing them back together.
