Rocket Accel (ロケットアクセル Roketto Akuseru?) is a Speed Formation maneuver used by Team Sonic, Team Dark, Team Rose and Team Chaotix in Sonic Heroes. When performing this move, the Power Type and/or Fly Type member of the team launch the Speed Type member forward at high speed.
When performing Rocket Accel, the Speed type member of the team rolls into a ball, while the remaining teammates get up behind the Speed type member. Once gathered, the other teammates push the Speed type member forward with extreme force, propelling the Speed type member forward at high speed as a yellow field forms around them, allowing the player to damage enemies caught in the Speed type member's path. Additionally, Rocket Accel can attract nearby Rings, activate switches, and have the same effects as the Tornado Jump when used near poles and enemies.
To perform Rocket Accel in gameplay, the selected team must be in Speed Formation. The player then has to hold down the action button (//) until the teammates have gathered behind the Speed type member and then release it to use Rocket Accel. However, if the player's timing is wrong, the Speed type member will perform their Solo Attack.
