The Dash Boost is a move that appears in Sonic Dash. When performing this technique, the user dashes forward as an unstoppable projectile.
When performing the Dash Boost, the user envelops themselves in an aura and blasts forward at high speed, plowing through and across any obstacles. The move's aura varies between users (Sonic, Tails, Amy and Knuckles' are blue, Shadow's red, Blaze's is orange-yellow, Silver's is cyan, Rouge's is pink, Cream's is light yellow, and Espio's is purple). Additionally, the users' means of dashing varies as well: Sonic, Amy, Knuckles, Blaze, Cream, Espio run, Tails, Rouge and Silver fly, and Shadow propels himself forward with his Air Shoes.
To use the Dash Boost in gameplay, the player must fill the Dash Meter by collecting Rings and then press the meter's Dash Button. Once initiated, the move cannot be stopped by any means. While performing it, the user automatically crosses bottomless pits and destroys all obstacles and enemies in their path, but the player cannot jump manually. In addition, the score multiplier doubles while the move is active. The Dash Meter steadily empties while the Dash Boost is used, and once it runs out, the move ends. It should be noted though that the Dash Boost cannot be used during boss battles.
When PAC-MAN or Ms. PAC-MAN collect Power Pellets scattered on the track, their Dash Meter will automatically be refilled and they can use the Dash Boost again.
