Invincible Mario

Invincible Mario is a form Mario assumes after using a Star. In this state, which only lasts for a few seconds, he is resistant to any enemy. Additionally, he is able to defeat them by simply touching them. He is not protected from falling into a pit or dying when time's up, however. Invincible Mario, just like the Star, made his first appearance in Super Mario Bros. Invincibility is depicted by a flashing, and, in later games, also color-changing character. Since this isn't really a transformation, Mario can become invincible and mantain the form he had before, for example, if he's Fire Mario and gets a Star, he becomes invincible, but he's still in Fire form. Wario can also become invincible in Wario Land: Super Mario Land 3 using a Starman as well. In the Mario Kart series, every driver could become invincible by collecting and using a Star, allowing him to make other drivers slide or tumble by touching them. In Super Mario Galaxy, there is a similar form, named Rainbow Mario.

In Super Mario Bros. 3 and New Super Mario Bros., there are some ? blocks that normally contain coins but that contain Starmen if Mario or Luigi is invincible.
