Okay, so Bowser kidnapped Peach in Super Mario Bros. Bowser was notably absent in Super Mario Bros. 2 because it was based off of Doki Doki Panic, as well as Peach being absent in SMB2 (in the real world as the game is all a dream). When Bowser and Peach literally returned in Super Mario Bros. 3, the Koopa Kids made their first appearance. As for Bowser Jr... that's an entirely different story for an entirely different time.
