In Mario Kart games, the Starman is referred to as Star, not Starman. Star's latest appearance was in Mario Kart Wii. They appeared in previous games as well. Stars have their same role as Starman, making the player invincible to any attack and they also go faster. When you have the Star's effect, you can destroy Bananas, blow up Bob-omb Cars and Spiny Shells, break Green Shells and Red Shells, keep moving after the final shake of the POW Block, flip vehicles and more. You can say absolutely nothing can stop you in this form. In Mario Kart: Double Dash!!, Stars had a smile (see picture below). Stars are powerful, but rare too. You are more likely to get them if you are below 6th place. In MKDD!!, you'll get Stars below 4th place. Yoshi's Egg in the MKDD, can bring out Stars too.
