As expected of the Blue Blur himself, Sonic is one of the fastest characters in the roster. As such, he relies on his incredible speed and mobility both in the air and in the ground to wear his opponents down, with several moves that keep him on the move and a Style Action being an effective way to close distance in a flash while dealing damage at the same time should it land.
However, despite his nigh-unmatched mobility and neutral game, Sonic is not all that tough and can be taken down quite easily if he gets careless. Not to mention, most of his most effective tools are used at close range, as his projectiles don't deal a whole lot of damage. In fact, Sonic's damage output isn't the greatest in the roster either, meaning he'll have to stay on the opponent's face as much as he can without taking too much punishment himself in order to come out on top.
