King Bowser Koopa - Super Mario Bros by @chub_ClausOfTheNewMoon

Bowser, sometimes known as King Koopa or King Bowser, is the main antagonist of the Mario franchise. Bowser in most portrayals is a persistent, threatening, and commanding villain who kidnaps Princess Peach, desires to defeat Mario and his friends, and runs an army to invade and take over the Mushroom Kingdom. His harsh and raging demeanor sometimes softens somewhat towards his loyal minions, he is considerate of their well-being. While Bowser is regarded as a respected leader from his troops and as a feared invader from his enemies, Bowser's usual brashness and short-temper can often lead him to not think his actions through or be willing to compromise. Although Bowser's role is being an intimidating authority figure in the Koopa Troop, he can be quite amiable sometimes, especially to Bowser Jr., where he is depicted as a loving father figure.
