Teenage Mutant Ninja Turtles Guide to the Universe

The Teenage Mutant Ninja Turtles Guide to the Universe, a single-issue comic from Palladium Books in 1987, serves as an atlas of the TMNT's cosmic corner of the Palladium multiverse. Primarily associated with the creative team behind the Teenage Mutant Ninja Turtles & Other Strangeness role-playing game, this guide expands the world by detailing alien races, planets, and technologies encountered by the Turtles. Though brief, it matters as an early, official attempt to map the Turtles' off-world adventures, bridging their comic origins with the wider Palladium game system.
