The most annoying character in the Super Mario Bros. series. Needs rescuing in nearly every game, from her first appearance as "Paula" aka Mario's girlfriend. She still is important, though. She has recently appeared in her own game (Super Princess Peach), has been in many mario spinoff games, and an become an iconic Nintendo character who can finally hold her own weight instead of riding on the Mario Bros.
The only move change I think she should have is making her standard special move use Toadsworth instead of just Toad.
