King Bowser Koopa Sr., known commonly as Lord Bowser, King Koopa, or simply Bowser, is the main antagonist of Nintendo’s Mario franchise and Mario's arch-nemesis. Bowser usually kidnaps Princess Peach to try and marry her and rule the Mushroom Kingdom and sometimes even the galaxy. Bowser is the ruler of the Koopas. He has shown a softer side and sometimes sides with Mario, but he has still remained Mario's archenemy. Bowser made his debut in Super Mario Bros. in 1985.
Bowser's appearance differs greatly from most Koopas,who look like bipedal turtles. Bowser is larger than other Koopas, and has sharp teeth and claws. He has a giant shell with spikes on them, so his enemies cannot jump on his shell. He has spiked collars on his arms and neck.
So far, Bowser has appeared as the main villain in the majority of Super Mario games, but has also made appearances as either a minor villain or even hero in several other games. As with most major Nintendo characters, he appears in most of the sport and party games of the Mario franchise. His stats in those games make him obviously powerful, but a little slow. In a few RPGs he also sometimes team with up Mario and Luigi. He is the main villain and the final boss of most sidescrollers and 3D platformers (Bowser Jr. is the main villain in Super Mario Sunshine). At the end of a few of them he seems to die (such as Super Mario Bros. and Super Mario 3D Land, where he falls into lava, Super Mario 3D World, where he explodes in a fireworks explosion, and New Super Mario Bros. Wii, when a castle falls on top of him), one such death near the beginning of the game he is revived on-screen by Bowser Jr., but at the end of most, is shown to survive. The chronology of much of these games, if any, is unknown. He is said to be "soundly defeated" (presumably killed, given the way it was said) by Mario prior to the events of Luigi's Mansion, but was presumably revived by Bowser Jr. before Super Mario Sunshine.
