Princess Peach

Princess Peach is a recurring character from Nintendo's Mario universe who appears in several Press Buttons 'n Talk lets plays. She appears in Paper Mario, Mario Party 2, Mario Party 3, Mario Party, Mario Party Advance, Super Smash Bros, Mario and Sonic at the Olympics, New Super Mario Bros U and Mario Super Sluggers.

Peach is characterized rather differently in different Lets Plays. In the Paper Mario canon, she is in a relationship with Mario, but in the Mario Party canon, she is actually dating Princess Daisy. Mario Party Peach seems to also have a bit of a crush on Bowser. Like all the other characters, she hates Donkey Kong.

Mario Party 2
Princess Peach is Anne Marie's chosen character in ''Mario Party 2. ''She takes home victories in both Pirate Land and Bowser Land. She ends the game in second place, having tied with Wario for boards won and stars, but having earned fewer coins.

In the opening scene of the game, Peach tries to stop the fight about the name of the new world by deciding that it should be called "Peach Land". This starts an even bigger fight between the characters that only ends when Clyde the Koopa-Troopa runs in to tell them that Bowser is trying to take over (again) and Toad decides that whoever defeats Bowser will get to decide the name of the world. Peach says 'no' to this idea but ends up participating anyway.

In Pirate Land, Peach seems to have been cursed to never get across the bridge. She gets cannoned off every time she tries to cross. Despite this, she manages to save enough coins to steal one of Luigi's stars, sabotages him in minigames multiple times, and then gets one of his stars through a chance time, propelling herself to victory. She has a sword fight with Cap'n Bowser, which she wins, and then Toad proclaims her the Super Star of Pirate Land.

In Western Land, Peach at one point strands herself and Luigi on a mountain in a minecart where they will never be able to go home or shower again, but somehow they manage to make their way back in time for the end of the map. Wario, Peach, and Luigi's intense back and forth stealing of stars and coins throughout the map is what ultimately allows Donkey Kong to win, much to their chagrin.

Peach gets an early lead with coins in the cursed Space Land, but then, because Bowser's a communist, he takes them and redistributes them amongst all the players.

In Horror Land, Peach utilizes the legendary double swing to great effect in a minigame, knocking out both Wario and Luigi in one shot. Luigi almost cries, saying he "thought it was only legend. Only in the sacred scroll...It was amazing. It was the most beautiful thing I ever saw in my life." But Peach, admittedly, doesn't think that it was very impressive. Throughout the map, "Evil Luigi" occasionally emerges, trying to prevent Peach from getting any coins, and generally succeeding. Peach doesn't get any coins during Horror Land, and if she does, they are immediately taken from her.

In Bowser Land, Peach finally buys the first star more than halfway through the game. She maintains a strong front throughout the map. It is implied that Toad is helping Peach win because she's his ruler and he will be punished by penalty of death if he doesn't. When confronting Bowser, Peach gathers all of her strength and spins Bowser around in circles very fast before catapulting him into space and killing him. Toad declares her the true Super Star of Mario Party (even though she doesn't win the PBnT tournament).

Mario Party 3
Anne Marie switches her chosen character to Daisy in Mario Party 3, but Peach still appears in Story Mode.

Peach also appears in the beginning cut scene of the game where she displays reluctance to play Mario Party again, saying that she thought it was over and that they were finally free. This may be why she let Princess Daisy take her spot in the game.

Mario Party
Peach returns as Anne Marie's chosen character in Mario Party. Although Mario Party is technically the first game in the series, in the PBnT lore, it chronologically occurs after the first 2 games, because Toad sends the main characters back in time. All of the main characters have, however, lost their memories in the time jump.

Trivia

 * All the Mario Party minigames were constructed with funding from Peach's extremely high taxation of the mushroom kingdom. Every Toad is taxed 97% of their income.
 * According to Wario Land 4, Peach and Wario have a surprisingly close friendship. They started out as Facebook friends around 12 years ago, but over time found out they had a lot in common and grew closer. Wario worries that Mario isn't good for Peach and believes that she could do better.

Quotes
Peach: (to Bowser) Can you change your status from 'it's complicated', cause it's not really complicated.

Bowser: Oh, it's really complicated. I'm just- ya know, we're talkin'. Ya know, we're like on and off, ya know, it's like a 'will they, won't they?', it's like tension.

Peach: No, it's just won't they.
