Super Sonic

Super Sonic (tenative name) is a form Sonic the Hedgehog takes, after obtaining all 7 Chaos Emeralds. This appears in SSBB as Sonic's Final Smash.

When Sonic transforms, he gains the ability to float around the level at will. The transformation lasts for 15 seconds and he is completely invincible in this form. Any opponents he collides with will take 16% damage upon impact and very high knockback. It is similar in function to Pikachu's Final Smash, Volt Tackle, except that he cannot go through platforms like the Volt Tackle can, and has knockback unlike Volt Tackle.
