Dana Sterling - the future daughter of Max aand Miriya - has joined the current timeline attempting to stop a deadly time loop. The Invid's Regress has concocted a deadly plan to interfere with reality and the SDF-1 has been under attack from Invid forces... And now the crew of the SDF-1 have headed to Invid space for a battle with the Regress, the Invid, and the Over-Mind...

After an attack by an alien race – the Zentraedi – Earth’s Super-Dimension Fortress was forced to space-fold away, taking a chunk of Macross City with them. The SDF-1 is now in the midst of a long journey back to Earth. The humans foiled a more recent attack by the arrogant Zentraedi Commander Khyron, but Breetai is hatching a new plan to infiltrate the SDF-1… In the meantime, Claudia is investigating how Captain Gloval died, and on Minmei’s birthday, Rick closes in for a kiss…

An ancient force threatens the Earth as well as worlds on the far side of the universe.

Dana’s arrival created a splinter timeline where she was never born, where everything feels like her past… but nothing is quite right. She doesn’t belong but has no way to return to her reality – if it even exists anymore. But now an opportunity has arisen in the shape of two mysterious spaceships able to travel the multiple realities of the “Protoverse”. Could this be Dana’s path home? The pilot of one of the vessels appeared to recognize Dana, and later got into a brawl with Miriya. The other pilot, who had seemingly targeted Dana for elimination, crashlanded in the wasteland outside New Macross City… His Battloid and unconscious body were discovered by Jack Baker and Karen Penn – and he seems to be Rick Hunter! Seconds later, a giant hand smashed out from beneath the ground…

Based on the cult classic animated series, ROBOTECH: THE MACROSS SAGA VOL. 4 is a sci-fi extravaganza of fast-paced action, high-tech battles, and burgeoning romance. Years ago when the SDF-1 crashed on Earth, the world knew that the alien spacecraft was the harbinger of an extraterrestrial invasion. Using the technology from the galactic warship, humans quickly began to develop biomechanical weapons to prepare for the upcoming onslaught. Now as the war reaches a fateful critical stage and another hero falls in battle, the alien Zentraedi enact an aggressive campaign to destroy the Earth's only hope of victory, the lost SDF-1 spaceship.
