Super Sheet (スーパーシーツ, Super Sheet) is Dr. Mario's version of Cape. It deals more damage than Cape (up to 12% rather than 10%). Just like Mario's Cape, the sheet starts to reflect projectiles at frame 6. A disadvantage is that Super Sheet only stalls Dr. Mario once in Melee, and not at all in Super Smash Bros. 4 and Ultimate, making it less useful as a recovery option. The sheet has the same multiplier as the cape - 1.5× when a projectile is reflected.
In Super Smash Bros. 4, Dr. Mario can reflect projectiles behind him, as he must swing it from his back upon use, though this requires precise timing. The move has more vertical but less horizontal range than Mario's Cape. In SSB4, it also has a longer window of time to reflect projectiles than Mario's, making it easier to use as a reflector.
In Ultimate, it gains a different animation to reflect its greater vertical range compared to the Cape. Additionally, it now forces opponents with a mirrored stance to show their backsides once reversed. Reflected projectiles are now stronger than those reflected by Cape as well, as Super Sheet's multiplier is x1.6 instead of x1.5. The Super Sheet has recevied a change in Ultimate. The duration of the reflect hitbox now comes up at the frame 9 instead of the frame 6, decreasing his safety normaly but to compensate for this, if a projectile comes close enough to Dr. Mario, the attack becomes faster and reflects back the projectiles faster too.
Special Move customization was added in Super Smash Bros. 4. These are the variations:
Super Sheet does not have a direct reference in the Dr. Mario games; instead, it is a move based on Mario's Cape move.
In Super Mario World, the Cape is a power-up obtained from the Cape Feather, which transforms Mario into Cape Mario. While wearing a Cape, Mario can perform a spinning attack, using it to attack enemies and destroy most projectiles. Additionally, by holding the jump button while airborne, Mario can slow down his fall. The cape can also be used to fly great distances after a running start: in this state Mario can stay airborne indefinitely by diving and pulling up at regular intervals, which allows him to skip large portions of some levels. The Cape's floating capabilities in its source game could have inspired its ability to stall Mario in midair in Smash Bros.
