King Bowser Koopa Sr, also known as King Koopa, and also known (in Japan) just by his surname Koopa, is the main antagonist of the Mario series. And is the archenemy of Mario and Luigi as well as Pooh and friends He rules over the turtle-like Koopa Troopa race and is constantly striving to expand his kingdom by conquering the Mushroom Kingdom, although his plans are always spoiled by his arch-enemy Mario. He's in love with Princess Peach, and his attempts of conquest always include kidnapping her in one form or another.

As a matter in fact, in the "Pooh's Adventures", he's the big bad villain ever, and have a partnership with Sunset Shimmer (Oposite).


Bowser's looks and personality have, as with most early Nintendo characters, slowly evolved over time. Most of his defining characteristics have remained the same, though. His most recognizable features are his spiked shell, red mane, and spiked cuffs, which except for the mane have been prominent features of Bowser in all of his appearances. One point of debate over the time has been Bowser's size, which seemed to vary in every one of his appearances. Most of the time, he is about twice the size of Mario. Plus, His personality varies depending on his role in the plot. In the main platformers, where he is the main villain, he has a very dark, brutal and serious disposition. In the RPGs, he shows some more amusing sides of himself, as he is shown to have a talent for sarcastic wit, works very hard to live up to the "evil king" image, and very often displays a shortsighted lack of common sense. The most prominent part of his personality, however, is his confidence. When he decides to help the other denizens of the Mushroom Kingdom against a common foe, it is mostly because of his own ego. In his mind, the only one allowed to kidnap Princess Peach, destroy Mario and/or conquer the world is himself, and he flies into a rage when other villains attempt to usurp his position as "the biggest, baddest brute around".


So far, Bowser appeared as the villain in many Super Mario Bros. games, but 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 final boss of most sidescrollers and all 3D platformers (although Bowser Jr. is the main villain of Super Mario Sunshine at first). 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.


Throughout the series, Bowser has always been seeking to massively expand his power, which he mostly tries to accomplish by acquiring magical artifacts and the resulting conquest of whatever it allows him to conquer. In addition to this he almost always kidnaps Princess Peach, whether she has any actual relevance to his plan or not. This is due to him being in love with her, and the fact that Peach possesses a unique ability called Heart Power that is a genetic mutation passed down by the royal Toadstool line that enables the possessor to channel their emotions into magical power. Although he often reaches his goal of conquest, he is always stopped by his archenemy Mario, which made him build both deep hatred, but also deep respect towards him. This respect mostly shows when he is forced to cooperate with him, which usually happens when a force more evil and more powerful than himself appears (as was the case with Smithy, Cackletta, or Count Bleck). In those situations he usually swallows his pride and sacrifices himself to help the heroes and save what he intends to conquer.

Appearances in other media

Bowser, under his 2 names "King Koopa" & "President Koopa", is the main antagonist of the 1993 live-action sci-fi fantasy, adventure, comedy movie Super Mario Bros the Movie which is loosely based on the popular Super Mario Bros. videogame. He was portrayed by the late legendary actor Dennis Hopper.

Mario and Luigi find themselves in a strange dystopian parallel world where a human-like race evolved from dinosaurs rather than the mammalian ancestry of true humans in a Manhattan-like city. 65 million years ago, a meteorite crashed into the Earth and in doing so ripped the universe into 2 parallel dimensions. All the surviving dinosaurs of the time crossed over into this new realm. Iggy and Spike turn out to be henchmen (and cousins) of the other world's germophobic and obsessive dictator, King Koopa, descended from the T-Rex. However, the two have failed to also bring a mystical rock possessed by Princess Daisy (Princess Peach Toadstool in the live-action version]], a meteorite fragment which Koopa is trying to get in order to merge his world with the human world that separated from Koopa's world during the meteor strike. It turns out that Daisy is the Princess of the other dimension but when Koopa overthrew Daisy's father (and turned him into fungus), Daisy's mother took her to New York using the inter-dimensional portal. The portal was then destroyed, killing Daisy's mother in the process; but when Scapelli was blasting at the cave, the portal was reopened. When Koopa hears about the re-opening of the portal, he sends Spike and Iggy to find Daisy and the rock to merge the dimensions and make Koopa dictator of both worlds. Spike and Iggy, however, who had grown more intelligent after being subjected to one of Koopa's experiments, decide to turn on Koopa and join forces with Mario and Luigi. Koopa thinks only Daisy can merge the worlds, but Mario and Luigi were just in the wrong place at the wrong time. Daisy is eventually rescued by the plumbers, along with the help of Toad, a man punished by Koopa for performing music protesting his reign, then condemned to be "devolved" into a Goomba.

Eventually, the two worlds merge and Koopa inadvertently devolves Scapelli into a primate while aiming for Mario, but Luigi and Daisy take back the rock and the worlds separate again. Mario confronts Koopa and eventually wins when he and Luigi devolve him, transforming him into a ferocious, semi-humanoid Tyrannosaurus. Koopa then leaps out for a final attack but Mario and Luigi destroy him by devolving him further into primeval slime. Daisy's father, the king named Bowser, turns back to normal and reclaims control over the kingdom stating he loves those plumbers. The citizens destroy anything involving Koopa. As the brothers return home, Luigi and Daisy admit their love for one another but Daisy cannot return to New York until the damage caused by Koopa is reversed and she spends more time with her father. Mario rephrases Daisy's words to Luigi but he does not care. A deeply hurt and saddened Luigi kisses her goodbye and the two brothers return to New York, while Daisy watches them leave. About three weeks later, Daisy returns for Mario and Luigi's help in fighting more villains. Meanwhile, Mario and Luigi's story is televised, giving them the name; "Super Mario Bros".

He was mentioned in Winnie the Pooh Meets Tarzan, as having recruited Clayton to bring him gorillas as sacrifices to his ever-growing hunger. His name was also mentioned by the Coachman in Winnie the Pooh Meets Pinocchio where the Coachman was thinking about given the donkeys to him. After the Pooh Star Wars Mini-series ended, Bowser teamed up with Divatox to try to bring upon the end of the world yet again with the help of his brother, Maligore. Bowser and Maligore were defeated, which forced the koopa king to ally himself with the Joker in order to help Shredder defeat the TMNT. He and his family made a cameo in Pooh's Adventures of The Muppet Movie. In Pooh's Adventures of Cool Runnings, He and family along with Dr. Eggman and Metal Sonic have become good guys for one time and joined Pooh and his friends to win the Winter Olympics, but they soon left the celebration so quickly.
