Angry Sun

The Angry Sun is an enemy from the Mario series.

Super Mario Bros. 3
The Angry Sun first appears in Super Mario Bros. 3.

In the game, the Angry Sun shoots out flaming rays to attack Mario. Sometimes it even swoops downwards. It appears in an untitled desert level in World 2 at first. Then in World 8-2. It can be defeated by a Koopa Shell, Starman or hammers.

Mario Kart DS/Wii
The Angry Sun reappears in Mario Kart DS and later in Mario Kart Wii when the level was ported to the game.

In the game, the Angry Sun appears in the course Desert Hills. Here, it is a hazard in the area as it shoots fireballs and Fire Snakes down at the player to slow them down.

Mario Kart 7
While Angry Sun doesn't directly appear, his Super Mario All-Stars sprite makes a cameo on carpets, jars and such in Shy Guy Bazaar.

Trivia

 * The Angry Sun highly resembles a more angry version of the Baby Sun from The Teletubbies. Though, The Teletubbies came after Super Mario Bros. 3.
