Super Mario
Most of these games, except Super Mario Bros. 2, Super Mario World 2: Yoshi's Island, and the Super Mario Land series, are about Mario and, normally, his brother Luigi and sometimes his best friend Yoshi, in their adventure to search for and save Princess Peach from Bowser, who wants to takeover the Mushroom Kingdom, or another place, depending on the game. The Mario brothers' adventure is not easy, however, as they need to face Bowser's troops all over, who try to stop the brothers' attempts to save the princess.
