Semi Super Mecha Sonic is a form Mecha Sonic takes after obtaining 4 Chaos Emeralds. This power appears in Super Smash Bros. Smash Wars as one of Mecha Sonic's Final Smashes. When Mecha Sonic transforms, after saying "I'LL CRUSH YOU!!!", he gains the ability to fly around the stage at an incredible speed like Super Sonic. Semi Super Mecha Sonic can attack in this form by simply ramming into opponents, and can shoot his energy balls and beams at them. The transformation lasts for about 15 seconds.
