Getter Robo Arc is one of the most unusual Getter Robo anime ever, doing what none of its predecessors even bothered to try: Be a generally faithful adaptation of the manga. This choice is all the more unusual because 1) the manga never finished, and 2) watching any (or even all) of the previous Getter Robo anime only prepares you to a certain degree. But Getter Robo Arc has different priorities than many anime, including its predecessors, and that’s to be a letter of love and gratitude to the original creator of Getter Robo, the late Ishikawa Ken.

Getter Robo Arc is the story of Nagare Takuma, son of the original head pilot of Getter Robo, Nagare Ryouma. Having experienced tragedy and now filled with a desire for revenge, he travels to the Saotome Research Institute (the home of Getter Robo) to get some answers. However, heading the Institute is his father’s old co-pilot, Jin Hayato, and the old scientist recognizes in Takuma the same fiery spirit as Ryouma. Hayato draws Takuma into piloting the mighty Getter Robo Arc against a mysterious force from beyond the cosmos bent on wiping out humanity known as the Andromeda Stellaration, and joining him are Takuma’s friend Yamagishi Baku, a psychically gifted monk whose older brother also has ties to Getter Robo, and Shou Kamui, a half-dinosaur descended from the first Getter Robo’s enemies. As they battle, their struggle takes them to the core truths of what the mysterious “Getter Energy” is.

It’s difficult to exaggerate how varied the Getter Robo anime prior to Arc have been. Sometimes they’re approximate counterparts to manga versions with the edges shaved off a little, like with Getter Robo, Getter Robo G, and Getter Robo Go. Sometimes they’re heavily reimagined sequels and reboots that play with elements of the franchise like Lego blocks, as is the case with Shin Getter Robo Armageddon, Shin Getter Robo vs. Neo Getter Robo, and New Getter Robo. So while Getter Robo Arc is supposed to be the last manga entry and the direct sequel to every manga version before it, watching literally every anime that has come out before will give you a rough preparation for what’s going on, but there will inevitably be a lot of blank spaces to fill out in terms of understanding. Someone coming in with this as their very first Getter Robo anime may feel lost for at least two or three episodes.

Yet, even with this confusing aspect of the series and animation that comes across in the best of times as desperately trying to make the best of limited talent and resources, I really enjoyed the ride that Getter Robo provides. Even if Takuma, Kamui, and Baku can never stay on-model from scene to scene, the anime conveys their intensity in spades. Though the story feels like a rickety minecart, the franchise’s general emphasis on the positives and negatives of limitless human potential ring loudly here in a way that shows the original manga’s undeniable influence on works like Tengen Toppa Gurren-Lagann. And while the battles aren’t quite as gorgeous as the ones found in the 2000s OVAs like Armageddon, they’re still impressive and exciting. 

I didn’t go into this show knowing what I’m about to mention, but I think it can be important for fans to know an important SPOILER about the Arc manga:

It never finished.

Similar to Miura Kentaro’s recent passing and Berserk, Getter Robo Arc and Getter Robo as a whole are in a state of limbo because of Ishikawa’s death in 2006. While the question of whether Berserk will continue is still unknown, the anime version of Arc barely adds anything extra to the cliffhanger that greets viewers by the end. I can’t say I’m entirely satisfied with that approach, as I think it wouldn’t have been a terrible idea to at least try—the manga’s still there, after all. But much like with Miura and Berserk, it might not have felt appropriate to take a generally faithful manga adaptation to a conclusion not envisioned by an author like Ishikawa, who clearly had an entire universe of Getter in his mind.

Overall, Getter Robo Arc comes across as crude and inconsistent in execution, yet filled with love and passion. In a way, it perfectly encapsulates the Getter spirit. It does make me wonder if we’ll ever see more Getter Robo anime, but I think that’s, in a way, an inevitability.
