Acceleratle is one of Hero's Down Special Moves available from Command Selection. It has an MP cost of 13.
Overview[]
Hero will enter a stance and emit a green aura. For ten seconds, Hero's movement aspects such as air speed and acceleration, ground and dashing speed, and falling speed will drastically increase, operating as a combination of Shulk's Jump and Speed Monado Art, or more similarly Lightweight. Accereratle virtually gives Hero the best mobility in the game, being capable of outrunning Sonic and having one of the highest jumps of the game, allowing him to approach, combo, and recover easily. However, the speed increase to Hero's movement comes at the cost of taking 1.1x more knockback, making him easier to launch and KO.
