Bowser

Bowser, sometimes known as King Koopa (Japanese: 大魔王クッパ, Daimaō Kuppa, which translates into "Great Demon King Koopa" or "Great Sorcerer King Koopa", the latter being used in the manual of Super Mario Bros.), is a major character and the main antagonist of the Mario franchise. He is a large, powerful, fire-breathing Koopa who leads the Koopa Troop, an antagonistic organization of turtle-like creatures, and has been the archenemy of the Mario Bros. since his debut in Super Mario Bros. He has repeatedly kidnapped or attempted to kidnap Princess Peach with the ultimate goal of defeating Mario and taking over the Mushroom Kingdom.

Why He Rocks

 * 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. 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 ranging from a threatening, yet humorous villain to a playable anti-hero. 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.
 * 2) He is one of the most memorable video game villains.
 * 3) His famous rivalry with Mario.
 * 4) His famous father and son bonding with Bowser Jr.
 * 5) He has a perfect villainous design.
