Badges are the primary form of customization in Paper Mario: The Thousand-Year Door. Each badge has a BP cost and provides a unique effect, such as increasing attack power (Power Plus), boosting defense (Defend Plus), granting new abilities (Multibounce), or altering combat mechanics (All or Nothing). You can find badges in hidden blocks, as battle drops, from shops, or by trading Star Pieces with Dazzle. Experiment with different combinations to create powerful builds. Some badges are partner-specific (e.g., Power Plus P), while others affect Mario directly. Collecting all badges is a significant post-game challenge.
