Speed Up is an ability that appears in the Sonic the Hedgehog series. When utilizing this ability, the user increases their speed.
Sonic Adventure 2
In Sonic Adventure 2, and its remake Sonic Adventure 2: Battle, Speed Up is one of Sonic the Hedgehog, Shadow the Hedgehog and Amy Rose's special attacks. In Sonic Adventure 2, Metal Sonic can also use Speed Up. When using Speed Up, the user emits blue sparkles and becomes able to run at speeds exceeding their regular top speed. In gameplay, Speed Up increases the running speed of the playable character for ten seconds, similar to High-speed Shoes.
Speed Up can only be performed in the games' two-player mode. To use it, the player must press // on the ground after collecting a set number of Rings. To use it again, the player has to collect the same number of Rings. For Sonic and Shadow, the player has to collect twenty Rings. For Amy however, the player only has to collect ten Rings.
In the console/PC version of Sonic Generations, Speed Up appears as an equipable Skill for Modern Sonic. Like in Sonic Adventure 2, it increases Sonic's overall speed, but it now passively affects his maximum speed for as long as the Skill is equipped, rather than giving the user a short burst of speed upon use.
To unlock Speed Up, the player can buy it at the Skill Shop from the beginning of the game for 300 Shop Points. It can only be equipped to Modern Sonic and costs twenty Skill Points to be equipped.
