Prinnies are recurring beings in the Disgaea series. They are the reincarnation of sinful humans' souls, and one of Nippon Ichi's most identifiable character races. Ever since their first appearance, they were considered the series' unofficial mascots.

A Prinny (プリニー Purinī), romanized as "Plini" (from the original term "Plinian Squad") in the The World of Disgaea artbook, resembles a small, usually blue, pouch-wearing penguin with disproportionately small bat wings and two peg legs where feet would normally be. When thrown, it explodes on impact. A common trait of the Prinnies is their upbeat attitude, lazy and unintelligent personalities, their signature pirouette spin, and frequent use of the word "dood" (as an interjection - they constantly end their sentences with "-ssu", a diminutive slang form of "desu" used by 'punk teenagers' in the Japanese dialogue). According to Valvatorez, the inclusion of "dood" is mandatory Prinny behaviour and Prinnies who fail to include it in their lines face severe punishment.
