Often the most common item in the games, Rings can be found everywhere in the primary playable levels. Aside from the main setting on earth, Rings are known to exist in underground caverns, on-board space stations, in outer space, on natural satellites and alien planets, inside cyberspace and even in alternate dimensions. It is not known where Rings come from and no backstory has been given for them, except that they are spread all over the world of Sonic the Hedgehog. Rings' unique properties also allow large amounts of them to carried at once, although it is not known where one puts them as they apparently disappear when picked up not even a genius like Tails knows for sure where they go. While appearing nothing out of the ordinary, Rings contain an unspecified form of energy referred to as " Ring Energy" which has energizing effects on machines, living beings and Super States. On their own, they spin around in one spot and either lie close to the ground or float in midair. The size of Rings varies in certain games in-game sprites and models show them being about half the size of the playable characters, while certain cutscenes or promotional material show them being small enough to be held in the palm of the hand. The Rings' design is based on either the basic and round-edged wedding rings or solid brass round rings.
