Angry Sun

The Angry Sun, or simply Sun, is a small, evil sun that first appeared in Super Mario Bros. 3. It initially looks similar to an actual sun, but is only slightly bigger than Mario and Luigi and has a furious-looking expression.

Super Mario Bros. 3
The Angry Sun appears in two levels of Super Mario Bros. 3. The first time it appears is in, and the second time in World 8-2, in the heart of the Koopa Kingdom, Dark Land. To attack Mario, the Angry Sun swoops down in a U-shaped arch, attempting to hit the plumber. The Angry Sun can be destroyed by a Koopa Shell, or with hammers from the Hammer Suit. However, if the player cannot 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 Angry Sun notably only appears in desert-like areas.

Super Mario Maker 2
The Angry Sun reappears as an enemy that can be placed in Super Mario Maker 2.

The Adventures of Super Mario Bros. 3
The 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.

The 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
The Angry Sun appears in the Desert Hills course of Mario Kart DS, where it shoots Fire Snakes onto the course. As Desert Hills returns in Mario Kart Wii, the Angry Sun reprises its role. Angry Sun sprites from Super Mario Bros. 3 are also printed on some carpets in Shy Guy Bazaar from Mario Kart 7 and Bone-Dry Dunes from Mario Kart 8 and Mario Kart 8 Deluxe.
