Invincibility

Invincibility(無敵 Muteki?) or Invincible Barrier is a stable power-up in the Sonic franchise. When the player hits the item box with Invincibility, the character will be surrounded by several, four-pointed stars or a sparkling colorful shield accompanied by a jingle tune. As its name indicates, the player cannot be harmed by enemies nor obstacles within the limit the invincibility is activated. It also destroys any enemy simply by the player running or jumping towards it. Invincibility first debuted in Sonic the Hedgehog(game) and has reoccurred in every game except for the Wii version of Sonic Colors.
