Ten years ago, a mysterious spaceship crashed on Macross Island… In the intervening years, the people of Earth have used the ‘Robotechnology’ from the ship to significantly advance their own technology. The ship – named by the humans as the Super-Dimension Fortress – actually belongs to a race of giant aliens, the Zentraedi. The Zentraedi attack and the crew of the SDF-1 are forced to space-fold away – taking a chunk of Macross City (and its 70,000 citizens) with them. The SDF-1 has been in the midst of a long journey back to Earth. Along the way, the SDF-1’s Captain, Henry Gloval, was killed under mysterious circumstances and Lisa Hayes took over his position… Rick appears to have gone blind, but has somehow developed a different kind of vision – possibly connected to the Protoculture that powers Robotechnology. He is now concerned that Minmei has also been affected… After being attacked by Earth and its Grand Cannon, the SDF-1 is now en route to Mars Base. A scarred Karl Riber, Lisa’s ex, previously reported as K.I.A. has mysteriously returned. Claudia was viciously attacked by an evil clone of Roy – the clone was then killed during a space battle with Vermillion Squad. The real Roy finally managed to escape the clutches of his captor – Dr Lazlo Zand. Meanwhile, Breetai, Miriya and a handful of the Zentraedi are rebelling against Dolza and planning to defect to the SDF-1…

A Warp In The Space-Time Continuum... The SDF-3 has remanifested from spacefold, but no one aboard has the faintest idea where they are. The ship appears to be grounded in some glowing fog, ensnared by light itself. Lang and Rem dub the phenomenon "newspace" -- but are at a loss to explain what it really is and who, or what, is keeping them there. For Lang, it seems like old times: The ship's Protoculture drives have disappeared. But other events are transpiring, unbeknownst to the stranded crew of the SDF-3. In Earthspace, the Ark Angel has been spared the fate suffered by the REF main fleet after the Invid transubstantiation. Vince and Jean Grant decide that the only logical course of action is to try and locate the SDF-3... On Haydon IV, something has awakened the Awareness -- and a mysterious change comes over the Haydonites. Exedore and the four Sterlings suddenly find themselves imprisoned beneath the surface -- as the planet leaves orbit, destination unknown... All of the pieces of this strange cosmic puzzle are about to come together...and the ultimate conflict is imminent. The question is: Will The Universe Survive?

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.

The SDF-1 has been in the midst of a long journey back to Earth. Along the way, the SDF-1’s Captain, Henry Gloval, was killed under mysterious circumstances and Lisa Hayes took over his position… Rick appears to have gone blind, but has somehow developed a different kind of vision – possibly connected to the Protoculture that powers Robotechnology. He is now concerned that Minmei has also been affected…. Minmei and Rick brought Minmei’s cousin, Kyle from Aluce Base to the SDF-1, and Miriya took revenge on Max Sterling by attacking him in space. The flight led to Miriya crashing through into the SDF-1, in the middle of Macross City and unleashing Invid warriors on Macross City as a distraction… Miriya was finally defeated and ejected out into space by Rick Hunter and Max Sterling, while the shock return of Karl Riber, previously reported as K.I.A. helped to turn the tide of battle. Meanwhile, Admiral Hayes of Alaska Base unleashed the devastating power of the Grand Cannon on the Zentraedi Battle Fortress, seriously damaging their flagship and forcing their fleet to withdraw. Back on board the SDF-1, Claudia attempted to confront Roy, not realizing he was an evil clone created by Dr. Lazlo Zand.

The Robotech saga continues – and it’s all out war between the humans and the Zentraedi… Having been attacked by the people of Earth, the SDF-1 has no option but to head to Mars Base. But Dolza’s shocking intentions for Earth draw the SDF-1 into more danger. Meanwhile, mysteries surrounding Roy and Minmei deepen, and events seem to be accelerating to a major climax… Written by Simon Furman (Transformers, Doctor Who) with incredible art by Hendry Prasetya (Mighty Morphin’ Power Rangers), Marco Turini (Assassin’s Creed, Dark Souls), and Pasquale Qualano (Doctor Who, Warhammer 40K). “A fantastically fun read, full of unexpected twists and great art. Each page is a treat.” – Bleeding Cool

The Robotech Expeditionary Force had been stranded on the far side of the galaxy as the result of damage to their Super Dimensional Fortress during the battle with the Invid hordes. Their chances for survival were slim. Suddenly, a starship unlike anything that had ever flown before appeared -- manned by an incredible assortment of beings who meant to challenge the might of the Invid Regent himself! REF volunteers signed aboard, with their might war mecha in tow, for a campaign that would either mean the total destruction of the freedom fighters or liberty for the planets of -- The Sentinels.

The Robotech Defense Force is caught between the fiercely opposed forces of Earthlings and the Zentraedi, survivors of the first Robotech War who are determined to inhabit planet Earth unopposed.
