Invincible

Invincibility is a power up present in numerous Sonic games. The power up first appeared in Sonic the Hedgehog and has since become a staple in the Sonic the Hedgehog series.

Useage
Invincibility power ups can be found Item boxes dotted througout various levels. When obtained, the player is surrounded by a starry shield and the player becomes to immune to most hazards for a short period of time. Whilst invincible, the player cannot be attacked by enimes or hazards, however the player is still vulnerable to crushing, drowning, and bottemless pits. Whilst invincibility is in effect, the background music usually changes to a redition of the game's main theme, or another theme exclusive to the powerup.
