Roto-Discs (also formatted as Rotodiscs, Roto Discs, and Roto-discs), or simply Discs, are Fire-Bar- and Spinner-like obstacles that first appear in Super Mario Bros. 3. Roto-Discs are found orbiting gray or red orbs, on which it is possible for Mario or Luigi to stand. Roto-Discs are nearly invulnerable; they can be destroyed if Statue Mario lands on top of one. Duo-Roto-Discs can also be found, and they consist of two Roto-Discs circling the central orb. If the player destroys one, the other disappears.
Aside from Super Mario Bros. 3 and its subsequent reissues, the only other appearance of Roto-Discs is in the Mini-Mario course in Bowser's Castle in Mario & Luigi: Superstar Saga and Mario & Luigi: Superstar Saga + Bowser's Minions. As a throwback to the previous games, they are obstacles that send Mario back to the beginning of the area if they connect with him.
