Princess Peach has been part of the Mario series since Super Mario Bros. for the NES. Peach was known as Princess Toadstool up until Super Mario 64, and now she is know as Princess Peach, (or solely Peach) and has appeared in most games in the Mario series with that name. In most games in which Peach participates, Mario seems to have to be her rescuer and she is usually taken away by the main villain of the series, Bowser. However, in Super Princess Peach, Princess Peach's first game in which she played the main roles, the script is reversed, since Peach has to save Mario, Luigi and a handfull of Toads from Bowser.
