Bowser is the main antagonist in the Mario series of games, usually kidnapping Princess Peach and trying to take over the Mushroom Kingdom. His first appearance was in Super Mario Bros. in 1985, and he has been in almost every Mario game since then, where he is usually thwarted by the moustached plumber, Mario, himself.
In his original appearance, he was shown to breathe fire and throw hammers. He kept his fire-breathing ability throughout the rest of the games, but loss the hammer throwing. He commands the Koopa Troop, meaning he has an entire army at his disposal who follow his every move. He has also been shown to have incredible strength.
