Gravity Bands are used in Sonic Riders: Zero Gravity by the characters who don't have an Ark of the Cosmos. Their function is similar to that of the Arcs, but they have no story importance and are simply used to let every character have access to the gravity-based moves that are a key feature in the game.
- Different characters wear their Ark of the Cosmos/Gravity Bands on parts of their bodies (with the exception of Amigo, who holds his on one of his maracas); Sonic and Eggman wear their Ark on their right wrist, while Jet wears his on his left wrist, both Knuckles and Shadow wear theirs on their ankles, Tails, Wave, Rouge and Silver wear theirs on their hips, Cream, Blaze, NiGHTS, and Amy wear theirs on their chests, and Storm wears his on his finger like a ring.
