Princess Peach

Peach's main role is to play Mario's damsel-in-distress, usually being kidnapped by the evil king of the koopas, Bowser.  This aspect of her character has been the subject of parody, including self-parody in games such as the Paper Mario series, in which her frequent kidnappings have resulted in her learning to plan ahead for the occasion.  Peach is friends of Mario and Luigi and has been portrayed to be Mario's love interest.  Peach also has a sidekick named Princess Daisy and are said to be best friends.

Peach first became a playable character in the North American Super Mario Bros. 2.  Later playable appearances include Super Smash Bros. Melee and Brawl, Super Mario RPG, and Super Paper Mario, in addition to her appearances in numerous Mario-themed sports games.  She has also starred in her own platforming game, Super Princess Peach, in which the classic roles are reversed and she adventures to save Mario and Luigi.

Peach's video game voices has also seen numerous voice actresses.

In Hotel Mario, Peach was voiced by Jocelyn Benford.

Mario Golf 64 saw a new Peach voice actress, being Jen Taylor, who also voices Halo's Cortana.  Jen Taylor has also voiced Peach in Super Princess Peach, Mario Hoops 3-on-3 and Mario & Sonic at the Olympic Games.  Jen Taylor's Peach voice can also be heard in Super Smash Bros. Brawl over the Wii remote speaker when a player selects Peach.

In 2005, Nintendo gave Peach a new voice actor, Nicole Mills.  Mills' voice can be heard in Mario & Luigi: Partners in Time and Super Mario Strikers.  Mills also does the voice for Baby Peach in Mario & Luigi: Partners in Time, Yoshi's Island DS and Mario Kart Wii.
