Bowser (Earth-1344)

"Hear this! I will kidnap Peach OVER and OVER until I pull it off! And no one can stop me! Losing is not an option! And neither is giving up!"

- Bowser

King Bowser Koopa, also known as Lord Bowser, King Koopa or simply just Bowser, is the primary antagonist of the Mario series and is the archenemy of Mario. Bowser most commonly kidnaps Princess Peach in order to marry her. He is the leader of the Koopa race. Although Bowser has joined forces with Mario in a few games, he has never ceased to kidnap Princess Peach and attempt to conquer the Mushroom Kingdom since his first appearance in Super Mario.

Personality
Bowser is a villain of pure evil. Cruel and ruthless, Bowser is a power-hungry tyrant whose intentions are to rule the Mushroom Kingdom and the entire Earth. His crimes range from kidnapping Princess Peach to acts of terrorism, giving him a reputation feared and dreaded by the entire world. He also does not doubt himself, and is always confident in his plans and appears to enjoy making fun of his victims.

One of Bowser's common traits is his insatiable lust for power and conquest. He thinks of everything in terms of power, and is always looking for ways to extend his dominion over the world. Several times, Bowser has shown to possess an arrogant sense of entitlement. Indeed, in Super Mario Galaxy, it shown that political power is not enough for Bowser. Bowser believes that only he is worthy to rule the universe and reshape it in his own image.

The games tend to portray different sides of Bowser. Bowser has appeared as a serious, relentless and legitimate villain, who will stop at no end to conquer the Mushroom Kingdom. At the same time, he can also be seen as a comic villain, reflecting the sympathetic aspects of his villainy as well as his clumsiness and ineptness, such as the love for his son, Bowser Jr.

Despite his opposing personality, Bowser has rarely shown emotions other than anger or hatred. However, it should be noted that, despite Bowser's evil nature, he is actually in love with Princess Peach and has tried to win her heart on several occasions. Bowser does not know, however, that his constant attacks on the Mushroom Kingdom has made Peach hate him.

In other words, he has shown that he has a soft side of him; that he cares for his son and sometimes helps Mario and Luigi in several stances.
