When Sonic transforms, after saying "Now I'll show you!", he gains the ability to fly around the stage at an incredible speed. The transformation lasts for about 15 seconds, and, while Sonic is transformed, he is completely invincible. Sonic can attack in this form by simply ramming into opponents; the faster he was going, the more damage is dealt. It is similar in function to Pikachu's Final Smash, Volt Tackle, except that he cannot go through platforms like Volt Tackle can, and has knockback unlike, and superior to, Volt Tackle. Sonic can't KO himself when he reaches the edge of the screen, regardless of how far he is going, but if he turns back to normal while he's too far away to recover, he'll be penalized with a self destruct. If it is used when the section of the Bridge of Eldin is materializing the move will end instantly. This is also useful when Sonic is falling down from the platform. This prevents him from being KO'd as he can break his fall. Also, if he has stopped or is going too slow, he can't even go through a fall through platform.
Sonic's Final Smash. The Chaos Emeralds give energy to all living things, and Sonic's gathered all seven of them, then used their power to transform into Super Sonic. His abilities in this form far surpass his normal ones, and he's even able to fly. He uses a lot of energy in this form, so he can only remain in it for a short time.
