From the Super Mario Wiki
An Angry Sun (sometimes referred to as The Angry Sun singularly) is a small, evil sun that first appeared in Super Mario Bros. 3. It is not the gigantic celestial body that Mushroom World orbits, and is merely just bigger than Mario. This blazing creature is only found in two levels, making it a rare enemy.
Super Mario Bros. 3
Two Angry Suns appear in Super Mario Bros. 3. The first sun appears in World 2-. The second one is located in World 8-2, in the heart of the Koopa Kingdom, Dark Land. To attack Mario, an Angry Sun swoops down in a U-shaped arch, attempting to hit the plumber. An Angry Sun can be destroyed by a Koopa Shell, or with hammers from the Hammer Suit. However, if the player is unable to do this, they could also defeat it by finishing the level. In World 8-2, the Angry Sun can also be bypassed by taking either of the secret Warp Pipes near the beginning of the level.
The Adventures of Super Mario Bros. 3
An Angry Sun also appears in The Adventures of Super Mario Bros. 3, starting with the episode "Sneaky Lying Cheating Giant Ninja Koopas". During the episode, the Angry Sun, offended by Mario's statement that "the sun was in his eyes", appears to attack Mario and Luigi after they exit a Warp Tube from Prince Hugo's castle; after several minutes of fleeing the Angry Sun, Mario and Luigi manage to gain a Super Leaf and transform into Raccoon Mario and Raccoon Luigi. With their new powers, Mario and Luigi begin to fly away from the Angry Sun, who catches up to them and asks the two "flying raccoons" if they saw where Mario and Luigi went; Mario and Luigi respond to the Angry Sun's question by saying that they went to hide behind a cloud, which the Angry Sun hastily flies to.
An Angry Sun also makes a minor appearance in a later episode of The Adventures of Super Mario Bros. 3; "Do the Koopa". Here, it is shown dancing with a pyramid and a Sphinx in Desert Land. It is white, and for the first time, grinning. The scene of Mario and Luigi avoiding the sun's attack also appears in the ending credits.
Mario Kart series
An Angry Sun appears in Mario Kart DS. The Angry Sun resides in the Desert Hills course, where it shoots Podoboos onto the course. It does the same for this racetrack that reappeared in Mario Kart Wii. Angry Sun sprites from Super Mario Bros. 3 are also printed on some carpets in Shy Guy Bazaar from Mario Kart 7.
