Super Stars (a.k.a. Stars, Starmen, or Invincibility Stars) are items used in many Mario games, including theSuper Mario series and the Mario Kart series. If the Player gets a Star, they will become invincible. The user becomes temporarily invulnerable to all damage, except to hazards that would normally be fatal, regardless of powerups (lava, pits, time-over, getting crushed, etc). Any projectiles or enemies that come into contact with the user of the Star while it is activated are destroyed, damaged, or spun out (depending on the type of enemy and what game it is). The Star also increases the speed of the user substantially.</p>
Starting with Super Mario World, if the player collides and defeats eight enemies while invincible (five in Super Mario Land 2 and Super Mario 3D Land), they will get an Extra life. As they continue rampaging through enemies, they will keep getting extra lives for each additional enemy steamrolled until the Star's power wears off and they are no longer invulnerable. Touching another Star while already invincible will prolong the effect and allow the player to continue getting more lives.
