A partner is someone that permanently joins Mario on his adventure. They all have different abilites, both in battle and in the field. Partners are generally weaker than Mario, but are nonetheless extremely helpful. In Paper Mario: The Thousand Year Door, partners have their own badges designated by the letter P (partner); they still share Mario's Badge Points, however. In Super Paper Mario partners were replaced by Pixls. Finally, Mario does not have any battle partners in Paper Mario: Sticker Star. Mario's only partner in Sticker Star is Kersti , who helps Mario in the field (with minor exceptions for battle hints; she does not have any attacks of her own).
Mario has a total of 8 partners in Paper Mario and 7 in Paper Mario: The Thousand Year Door.
- Goombaria (Unused)
- Twink (Normally only a partner for Peach)
- In Super Paper Mario the partners in the game are known as Pixls. Unlike partners in previous Paper Mario games, Pixls don't have HP or take damage.
- Goombaria and Twink were going to be Mario's partners in Paper Mario but were scrapped.
- In Paper Mario: The Thousand-Year Door, all of Mario's previous partners were going to be in game but were scrapped. Only Bow and Parakarry make it in the final cut.
