Seventy-four episodes, countless skirmishes, and yet the last move is not the one fans expect. What finally breaks the cycle of invasion, and why does the farewell hit harder than the enemy’s fall?
For kids who grew up with giant robots on afternoon TV, few finales hit like Goldorak’s last stand. Episode 74 brings Actarus face to face with Grand Stratéguerre Véga in a lunar showdown that decides the fate of Earth, and what remains of Euphor. Beyond the explosions, the series bows out with a tender goodbye and a promise of rebuilding that still resonates. Here’s how that climactic battle unfolds, why it mattered, and where you can revisit it today.
A groundbreaking sci-fi phenomenon
Some finales linger because they resolve a saga while leaving a door open. That is the case with UFO Robot Grendizer, known to many fans as Goldorak. Created by Gō Nagai and produced by Toei Animation, the series first aired on October 5, 1975, charting a path for giant-robot epics that followed. Its blend of intimate stakes and galactic warfare still feels immediate, decades after the last battle faded.
The story so far: battles across two worlds
At its core is Actarus (Duke Fleed), a prince who escapes the fall of his home planet, Euphor, after the invasion led by the tyrant Vega. On Earth, he hides in plain sight at a space research center under Professor Procyon’s care, then rises to defend his new refuge. Across 74 episodes, Actarus fights back with the mighty robot Grendizer, joined by Alcor, Venusia, and Phénicia, their camaraderie hardening through every close call and counterstrike.
The final battle: “This is only goodbye”
The ending pivots on escalation and sacrifice. Vega masses his forces on the Moon, betting everything on a single, annihilating strike. Actarus and his allies launch a desperate counteroffensive, forming the Cosmorak to break Vega’s hold and give Grendizer room to strike. Even after a paralyzing ray snares the robot, the team shatters the field, and Actarus brings down Vega’s command ship with Grendizer’s ultimate attack, the Astero-Hache. The tyrant’s last charge dissolves in fire.
A heartfelt farewell and a hopeful future
Victory arrives with a cost and a promise. With Earth safe, Actarus and Phénicia choose to leave their friends and return to Euphor, intent on rebuilding what was lost. Their goodbye is tender, almost quiet after so much thunder. According to this reading of the finale, the series doesn’t revel in triumph, it leans into renewal: a homecoming, a second chance, and the fragile hope that peace can take root again.
Where to watch in the US
Availability for Grendizer in the US shifts over time. The series is not consistently on major American streamers, though official DVD or Blu-ray releases have surfaced periodically (catalogs change). If you are revisiting the saga or discovering it fresh, keep an eye on reputable US anime distributors and specialty retailers. The legend endures, waiting for the next clear path to your screen.
