Sonic is a playable veteran character in Super Smash Flash 2. Unlike the Super Smash Bros. games, he is not the only representative of the Sonic franchise — he is joined by his sidekick Tails. Most of his moveset is taken directly from Super Smash Bros. Brawl and his voice clips also come from said game. His sprites are based on his modern appearance, which includes Sonic Generations and Sonic Lost World. His pros are vastly overlooked by his inadequacies and that is why he second to last.
