Starman (Mario)
From the Nintendo Wiki, your gateway to information on everything Nintendo
Not to be confused with stars.
A starman is an item from the Mario series that makes Mario invincible temporarily. They hide in various blocks scattered across the Mushroom Kingdom. However, they are usually found inside hidden invisible blocks. In Super Mario Bros., Mario can jump up and hit a block with a starman inside. It then hops out and jumps along the grounds until either Mario gets it or it falls off stage. If the player gets the Starman, the player is able to run through enemies and not take damage. In the Super Smash Bros. series, if a player gets a star, he becomes invincible to all attacks, but the effect doesn't hurt the others players/CPUs.
