"Stars (a.k.a. Super Stars, Starmen, or Invincibility Stars) are items used in many Mario games, including the Super Mario series and the Mario Kart series. If Mario gets a Star, he will become Invincible Mario. The user becomes temporarily invulnerable to all damage, except to hazards that would normally be fatal, regardless of powerups. Any projectiles or enemies that come into contact with the user of the Star while it is activated are destroyed, damaged, or spun out. The Star also increases the speed of the user substantially."
