Princess Peach

Princess Peach Toadstool is the beautiful and graceful princess of the Mushroom Kingdom. She is often kidnapped by Bowser and is always rescued by Mario. She has also helped Mario save the world a few times and even starred in her own game where she rescues Mario, Luigi and the Mushroom Kingdom from Bowser. She has appeared in a few games alongside Sonic the Hedgehog. The first game to feature these two together was Mario and Sonic at the Olympic Games. She later appeared in Super Smash Bros. Brawl and Mario and Sonic at the Olympic Winter Games where she was a playable character in all 3 games. She seems to have good relations with Blaze, Amy, and especially Daisy.

Mario and Sonic at the Olympic Games
Peach made her first appearance in the Sonic series when she was featured in the game Mario and Sonic at the Olympic Games. She appeared as a skill character along with Waluigi, Tails and Dr. Eggman. In the opening for the game she is seen running on the 100m dash along with other major Mario and Sonic characters. She is later seen in the swimming event. In mission mode, she shares a rivalry with Amy.

Super Smash Bros Brawl
Her first appearance in the Smash Bros series of games was in Super Smash Bros Melee. Her standard special move was Toad, if she was hit, the damage would deflect onto the opponent. Her side special move was the Peach Bomber. In this move, she would use her rear end to smash into the opponent causing an explosion. In Super Smash Bros Brawl, the Peach Bomber would send out hearts instead of causing an explosion. Her up special move was Peach pulling out a parasol and floating gently down with it. Her down special move is where Peach can pull a vegetable from the ground and throw it at opponents. This move caused little damage, however, there is a slim chance Peach can pull a vegetable with a different expression on it's face and it deals a lot of more damage.

Peach reappeared in Super Smash Bros. Brawl alongside Sonic the Hedgehog. All of her moves were kept the same and a few were changed only by a little bit. Her dress was a lot more detailed in this game.

Mario and Sonic at the Olympic Winter Games
Peach's third appearance with Sonic was in Mario and Sonic at the Olympic Winter Games. She appeared as a skill character like the other skill characters from the past game with a new edition to the group being Silver the Hedgehog. Her rival in mission mode was still Amy. Peach, however, got a new winter outfit like the other girls in this game. This outfit was a mini pink dress with magenta sleeves and leggings. In the Nintendo DS version's Adventure Tour, Peach will join Mario and Sonic if they beat her in a Snowball Machine match.
