Princess Peach is a startable playable character from Ultra Smash Bros. IV and the princess of the Mushroom Kingdom of the Super Mario (series). She makes her fourth appearence since Super Smash Bros. Melee. She's already confirmed 2 days later after Captain Toad's and Nabbit's trailer alongside with Bowser. Peach is a princess who rules Mushroom Kingdom and a damsel-distress that always is captured by Bowser and rescued by Mario at the end of his games.
Samantha Kelly has the voice as Peach, not used from the Super Smash Bros. Brawl voiceclips, but she remastered the new ones.
Peach ranked the 32th place of the 103th (B) in the tier list behind Fiora and after Fox making her a high tier character. Thanks for her better double jump cancel and her air mobility for a projectile game with her turnips. It's a significant rise for Peach being a mid tier character in Smash 4.
