The Drop Dash is a technique used by Sonic in Sonic Mania and by Classic Sonic in Sonic Forces. By pressing and holding any jump button in midair after jumping, Sonic will charge up the move, and will instantly dash off in a short burst upon landing. However, the move cannot be performed if the player takes damage before landing. If the move is executed by Super Sonic, a mini-earthquake is set off and the boost will be greater.
According to The Taxman in an interview, the Drop Dash was designed with new players in mind.
