TMNT: Odyssey is a Teenage Mutant Ninja Turtles fan comic from 2015, written and self-published by Andrew Modeen and drawn by a number of artists — primarily Jim Lawson, one of the veteran artists from the original TMNT Mirage comic, but many other artists who have worked on TMNT have contributed to this comic, including Dan Berger and Rick Arthur; even A.C Farley and Rick McCollum & Bill Anderson have provided covers and back covers.
The comic serves as a sort of Grand Finale for the Mirage continuity as a whole, and to a lesser extent also for the entire pre-ViacomCBS TMNT franchise.
It's the year 2105 in the Mirage universe. An aged and blind Donatello, the last living Turtle, is about to die quietly in his sleep when Renet, the Timestress, shows up — also dying. The sorcerer Savanti Romero is back; and he's resurrected his wife Juliet, and the two have teamed up with the demon Mr Null (from the Archie version of the TMNT) and a mysterious entity calling himself "the Shogun," and they are seeking to not only remove the Turtles from time and space, but possibly end everything. In her final moment she bestows upon him her last powers of healing, time travel and teleportation, and begs him to save everything. A revived and more powerful Donatello proceeds to go back in time to each of his brothers' dying moments and pluck them out of the timestream to go for one last odyssey; one final romp through time, space and The Multiverse, in what might turn out to not only be the last battle of their lives, but also the greatest, as they have to stop The End of the World as We Know It.
With its focus on a multi-dimensional threat and the appearance of several versions of the Turtles and their allies and enemies, the comic might look a lot like a more serious and less kid-friendly Turtles Forever (the events of which are referenced briefly), but it's actually a reimagining and reworking of Andrew Modeen's earlier TMNT fanfic Transencion and its sequel Deliverance, (both available here), both of which preceded Turtles Forever by several years and featured characters from the various TMNT universes interacting, with a heavy emphasis on the Mirage and Archie universes. Even the character of the Shogun comes from Transencion, as does the way the Mirage Turtles team up with Slash from the Archie universe and Venus de Milo from Ninja Turtles: The Next Mutation.
TMNT: Odyssey was crowdfunded and initially available in a limited softcover run, but Andrew has also made a digital PDF version available for free.
The comic would later on get a sequel/prequel by the same creators and set in the same continuity called TMNT: Origin.
