Bowser

King Bowser (sometimes known as King Koopa) is a major character and the main antagonist of the Mario franchise. He's the Koopa Troop, an antagonistic organization of turtle-like creatures, and has been the archenemy of the Mario Bros. since his debut in the first Super Mario Bros, repeatedly kidnapping Princess Peach (or trying to do so) with the ultimate goal of defeating Mario and taking over the Mushroom Kingdom.

Why He Rules

 * 1) When Bowser was created, he was a typical villain without much personality beyond simply wanting to take over the Mushroom Kingdom. Later games started showing various different aspects of Bowser's character, depending on the nature of the plot.
 * 2) * While his platformer role continues to be that of a simple antagonist, his Mario Party antics typically depict him being more angry, childish, and mischievous than dangerous, and his portrayals in the RPGs range from a threatening, yet humorous villain, to a playable anti-hero.
 * 3) * Even when Bowser is acting as a protagonist in a game, however, he continues to insist he is an evil character, and his reasons for helping the protagonists are typically his own selfishness. In some games, he even breaks the fourth wall to do so.
 * 4) In multiple occasions, Bowser has plenty of showsmanship that could match that of his Sega rival Dr. Eggman, like his "World Bowser" theme park in Mario 3D World and when he dressed both him and Peach for his forceful marriage in Mario Odyssey.
 * 5) He might act tough, but Bowser does have a soft side underneath that intimidating shell (pun entirely intended). He's a single father who tries his best raising Bowser Jr., and perhaps giving him a mother may be the reason he always kidnaps the princess in the first place.
 * 6) He has a perfect villainous design for his species, combining standard Koopa elements with those of a fire-breathing dragon.
 * 7) In the crossover game with Sonic (a.k.a The Olympic Games), he had a good friendship with Eggman as villains.
 * 8) He shows to the nice to his minions are also nice since he treats them respectfully to them, making him a good boss of the Koopas.
 * 9) Scott Burns and Kenny James are awesome at making him sound like the goofy evil beast he is, and Jack Black is sure to give an awesome performance in the upcoming movie.

The Only Bad Quality

 * 1) He can lack common sense with his tactics and behavior at times.
