Inoffensive, which is more than what you can say for most Toei mecha anime around the time.
I have spent most of my times avoiding watching Toei adaptions of the Mazinger series, I gave the Toei show a shot because of its cultural significance and curiosity (two things I am driven by for many reasons) and I absolutely loathed Toei Mazinger. Gone was the silly, fun, violent, and charming qualities of Go Nagai's manga with its rather simple yet effective exploration of themes of war was replaced a show that hardly can be classified as a show as much as it was total rubbish bin material. Not only was the animation cheap and sloppy even for the time it was done, the characters were butchered into very lame archetypes that had generated at the time (Kouji's Toei personality is heavily based off Hideki Go in Return of Ultraman for instance) and it irritated me to no end that Sayaka was being treated so terribly by the showrunners because, as history always shows: "when things go down, the women suffer the most" when it comes to the failings of hardly classified scripts that repeated the beats of each episode over and over again. It seemed that most media around this time loved doing this, as Return of Ultraman (the show that basically a lot of these things were initially following as a template) had regressed of sorts with how it treated women as well.

Look, I have seen a lot of my fair share of monster of the week shows but this is one of the worst and most boring examples of them and this going on for 92 episodes made me lose my patience. Why would I wanna continue something that wouldn't even keep my interest?

Fast forward to a year later, I have been watching mecha shows all of 2025 as a big project of mine to become well versed in the subject and to also enjoy the thrill of having something new that maybe only a few people knew about and as a fun way to keep me on my toes I decided to make a roulette out of it and lo and behold Toei Grendizer had rolled onto my doorsteps. My friends who had seen it or seen some of it had said that this show will start taking influence from its rivalling competition "Combattler V" about 29 episodes in to keep viewer interest and that intrigued me. I as a fan of Grendizer U and the Grendizer manga was curious to see how this could adapt this story into .... 74 episodes really? While I am not one to complain about length per say anymore (I have seen Kamen Rider (1971), Ultraman Cosmos (2001), and Goranger (1975) so length can't seem to be a total problem right?)), Toei's name attached to a long show makes me suspicious because it becomes a matter of "when does it just shut down and become autopilot aka sucking", thankfully the show seemed promising as it opened its doors to me as it not only felt better than the likes of Toei Mazzy and Toei Getter, but it also felt a bit more livelier than them. This is in no part thanks to Nagai clearly being in the room for this one compared to Toei Mazinger Z, and while it really is up to the people who put it to screen (the screenwriters) to make them work.

As a whole, Toei Grendizer is fine. While it isn't slop like Toei Mazinger nor is it a misfire so hard it angers me (Daltanious), Toei Grendizer is a show that will have highs and then big lows and then for most of its 74 episode run sit in comfortably in the middle in a way that is not offensive as much as it is kinda uncreative and boring. The big points of the show are when it does status quo changes such as make Hikaru a more central and active main by giving her a ship to fly into combat with and when Maria shows up near the three-quarters mark, where the show becomes livelier as a result because it is doing what most of Toei's library at the time wasn't for mecha: it made women do something and didn't treat them like trash. Granted, Maria does get a few jobbing episodes here and there and it can get quite boring because it means they got tired of putting Kouji (a character who characteristically should be jobbing) in the ringer. The animation can vary from really nice to straight up ugly, the frames and cels can also range from beautiful to just straight ugly as well so it at least is consistent about it. While Toei Grendizer will never compete with its rival show Combattler V in the slightest, Toei Grendizer being the easy popcorn show or background noise show while Combi does its very strong plot threads, character work, action, and drama is a good enough sacrifice especially what came before this. Duke Fleed is a good enough protagonist here, the show does seem to throw out his early characteristics for about 85% of the show until the finale where they just bring it all back for one last hurrah for some reason. I would def say in order of likability, the main cast is as follows:
1. Hikaru
2. Maria
3. Duke Fleed
4. Kouji Kabuto
As a whole, this show does the job well as being an easy sit down and while some episodes are straight rubbish and lame 70s shock value, the good episodes are pretty good and you'll be mostly sitting through the most serviceable mecha show of the 70s. Good for what it is, but if you are looking for a great show this might not be it and you should probably just go to Combattler, Voltes, and Daimos for that.

the pinnacle of Toei's Mazinger series [spoilers]
UFO Robo Grendizer first aired in Japan 50 years ago as the second sequel to the incredibly successful Mazinger Z, and it was the first anime to become a hit in Italy, France, and many Arab countries. But while it wasn't quite as popular in Japan as the first two series in the franchise and didn't sell as many toys, Grendizer stands far above Mazinger Z and Great Mazinger in the story that it tells and in the way that it tells it.

Let's get the simple stuff out of the way: UFO Robo Grendizer follows a young man named Daisuke Umon who is in fact Duke Fleed, the prince of another planet called Fleed. After his home was destroyed by evil aliens called the Vegan Empire, Duke takes the "guardian" of Fleed, the titular Grendizer, and crash-lands on earth, where he is found by Dr. Genzo Umon of the Space Science Laboratory. Joined by Koji Kabuto, the hero of Mazinger Z who has been relegated to sidekick, along with the eclectic Makiba family, UFO-obsessed father Danbei, young Goro, and Duke's sort-of love interest Hikaru, Duke Fleed and the Space Science Laboratory defend Japan and the earth from the Vega's march towards universal conquest.

If you've seen Mazinger Z or Great Mazinger, the setup should sound familiar. Grendizer on the surface is functionally the same as the previous two series: protagonist gets in super-powered robot and fights bad people want to destroy said robot and the entire world; cue episodic, monster-of-the-week show that rarely, if ever, deviates from the formula. Grendizer improves a lot of technical aspects over the past two series, like sound design and animation quality, but still feels like a pretty standard 70s super robot anime. But as I've said for every entry in this series so far, you don't come to these shows for a challenge to storytelling conventions or a breakdown of the human condition—you come to them because giant robots are fucking awesome; and sometimes, if you're lucky, these formulaic toy commercials will actually have something interesting to say.

Mazinger Z opened the door for this aspect of the super robot genre, and there were a few episodes sprinkled throughout it that played up some character drama and complex stories of enemy soldiers fighting against their will and issues of pride and confidence among the heroes. Great Mazinger then ran through this door, going as far as to talk about issues of race and the cost of war on innocent civilians. But UFO Robo Grendizer is what you find on the other side of this door, a series which takes the interesting ideas of love, war, personal trauma, and conflicting character dynamics and throws them into nearly every episode. And despite the fact that the show is episodic, it isn't afraid to have its characters change: Koji learns to manage his pride as he plays second fiddle to Duke; Hikaru begins to fight so she won't be a burden to her friends; Goro and Danbei both end the show more mature than they began it. Halfway through the series, Duke's little sister Maria is introduced, and she brings a great emotional weight and is so dynamic with the other characters that her presence really elevates the rest of the story.

Duke himself is a fascinating character. While he seems to not change all that much throughout the series, I don't think that's necessarily a bad thing because he is set up at the beginning of the story as a character defined by his past. Though he's usually the one saving the day in Grendizer, his primary conflict throughout the series is overcoming his own past and what has happened to Planet Fleed and the people that he loved. Because of this history, the conflict with Vega is much more interesting, much more personal. This is exacerbated during a number of episodes where Duke is brought face-to-face with other survivors from Planet Fleed such as his old lover and his best friend, and another episode in which a Vega soldier imitates his mother. Despite Mazinger Z and Great Mazinger both caring about their characters, Grendizer is the first in the trilogy to tie the conflict of its characters to the conflict of its broader plot, and this connection between the emotional side of the show and its narrative really works in its favour.

This isn't to say that the show doesn't have its issues. For example, plot points seem to be dropped pretty much on a whim. This happens a lot with the show's attempts at romance, with Hikaru's feelings for Duke and Koji's feelings for Hikaru seeming to vanish into thin air. Hikaru on the whole is sort of just there for the last 30 episodes or so, though she has her moments. And despite how well I think the show uses its monster-of-the-week formula, there are certainly some episodes around the middle that are boring and are, in my opinion, unnecessary bloat. That said, unlike the first two Mazinger series, I think the good here outweighs the bad. For the most part, even when there's no character development going on, even when the plot seems sort of stagnant, Grendizer is still enjoyable thanks to a good blend of lighthearted kids' show and and epic space opera.

The final seven episodes serve as a loosely-connected culmination of the series, where the Vega move beyond simply destroying Grendizer to conquering the earth because Planet Vega is incredibly unstable and will soon die. These episodes are, in my opinion, the highlight of the show as they up the emotional ante tenfold. Episode 68 is a brutal look at the horror of war and betrayal through the lens of Maria and her childhood friend Kane. Episode 72, which introduces Duke's ex-fiancee Rubina, the daughter of the King Vega, is for me the best episode of the entire Mazinger seires (and the first to make me cry). And the show's final scene which sees Duke and Maria leave the earth, venture across the cosmos, and return to Planet Fleed drove home to me just how far this franchise has come in terms of creating art within its commercialized formula. The shots as Grendizer flies across the stars remind me so much of later mecha series that I can't help but wonder if some young mecha animators and storytellers drew inspiration from this show as they did its predecessors.

Ultimately, Grendizer (and the Mazinger franchise as a whole) is a big piece of anime history that continually gets smaller and smaller in the rearview mirror. There's practically zero online discussion of this show, even less than Mazinger Z or Great Mazinger. I'm not so blind as to question why this is. It's easy, after all, to dismiss anime like UFO Robo Grendizer as "outdated" or "irrelevant" because of how far the industry and the artform has come in the 50 years since it first aired in Japan. Yes, the show is what it is: a 74 episode, monster-of-the-week, super robot anime. There are dozens of others like it, including two other shows in its own series that are both more successful and more influential. But I think that's missing the point.

I think it's important to know where the things you like come from, and though Grendizer isn't my favourite show of all time, it certainly helped lay the groundwork for some of them. While Mazinger Z will always be more famous, Grendizer will always stand out to me as a pivotal step in the evolution of mecha. Grendizer does what it does really well. And if you're interested in or curious about retro anime or the mecha genre, I think it's worth checking out. It might not be perfect, but it's definitely a good time. And along the way, it elevates the super robot from a campy and forgettable piece of anime history to something more interesting, more lasting, and more real.

"For even a single flower, Duke Fleed will risk his life" [spoilers]
Warning: This review contains spoilers for Mazinger Z, Great Mazinger and UFO Robo Grendizer

"For even a single flower, Duke Fleed will risk his life"

UFO Robo Grendizer is the third and final instalment in the Toei and Dynamic Planning co-produced Mazinger series. Starting with Mazinger Z in 1972, followed up by Great Mazinger in 1974 and Grendizer in 1975. It stars "Duke Fleed"— an alien prince who escaped from Planet Fleed years ago after being brought to ruin by the Vegans. That's "vay-guns" by the way, not "vee-guns". As far as I'm aware they're not vegetarian, though now that I think about it, you never really see them eat in the show so who's to say!

I actually have quite a lot of history with this show, being Kurdish, my parents actually grew up with it! I remember as a child we would always watch episodes together alongside Future Boy Conan. Though I never really was into Grendizer as a kid, so I was curious to see how I would feel about it now as an adult with a few mecha shows under my belt. Well, I'm happy to say my parents were lowkey cooking and were lucky as hell to have watched this as a kid!

The first thing that stood out to me about the show was how different Duke was compared to the other show's protagonists. Koji from Mazinger was kind of immature, rough, really hotheaded... and really misogynistic! Tetsuya from Great Mazinger in comparison was a lot cooler but still had a bit of an attitude. Duke, disguising himself as a human and going by the name of "Daisuke Umon" is very solitary, and almost reclusive. It's clear that the events of what happened to his planet still haunt him greatly. What I loved in particular was his pure adoration for all life, including nature. He goes at length talking about how beautiful Earth is while lamenting the destruction of the beauty of his own planet. On top of that his general mannerisms and the way he talks to others makes him legitimately feel like an alien who doesn't quite understand social norms. It immediately sets him apart from the other protagonists and it's just really damn cool in my opinion.

A big focus during the early episodes of the show is Duke's view on war and fighting. Even though he will still fight, he would much rather not because even if he wins, he will still inevitably damage some part of the world in the process. It's super cool to see how he grapples with this, there's an episode early on where Duke refuses to engage in a hand-to-hand fight for sport and is looked down upon by everyone for it. They saw it as a sign of weakness and didn't understand why he wouldn't engage with it. When chewed out by Koji, Duke says something along the lines of "Any fight, no matter how small, can always leave permanent scars, both physically and mentally" and it's something that's stuck with me ever since he said it. As it goes on, he slowly learns to accept that fighting is something he has to do if he wants to protect the Earth that he's come to know and love. It's simultaneously really cool and also depressing that he has to forsake who he is in order to defend...

One of my favourite aspects of this show is how they brought back Koji, which is quite frankly a genius choice. Watching Mazinger Z beforehand really enriches his character for me, I would describe him as being almost bloodthirsty in that show and that still rings true here. He doesn't share Duke's hate of war and in some respects really revels in it. Though you can still tell he's matured a bit (dropped the misogyny for one!) but is still pretty rough and just overall very cool! I love Koji very much and I was really happy to have him as a side character. The way he contrasts with Duke's personality and beliefs makes for some incredibly fascinating conflict early on, and seeing his rivalry slowly turn into genuine friendship and adoration for Duke is incredibly sweet to watch unfold. There are 2 episodes where Boss, a fan-favourite character from Mazinger Z and Great Mazinger makes a major cameo and they're some of the best episodes in the show. Seriously, Boss' second episode teeters on developing what feels like a genuine romance between Koji and Boss and it's legitimately so beautiful and heartwarming I teared up a little bit watching it!

Hikaru, a lady who happens to live with Duke on a farm, is lovely. It was incredible seeing her love for Duke develop. I especially love her wanting to fight and having to earn the respect and permission to do so, eventually getting her own ship, The Marine Spazer, to pilot. Unfortunately after she begins piloting the Marine Spazer, she ends up taking a massive backseat with hardly any development. It is pretty disappointing I will admit but the development she got up until that point is still fantastic and really cemented her as a great character to me.

I really love the villains in this show, they're still nowhere near as good as Mazinger Z's villains in my opinion as they lack the almost infectious charisma that they had. But they're sure a whole heck of a lot better than whatever Great Mazinger was trying to offer (seriously I cannot name a single villain from that show besides the revived doctor hell and the general of darkness, and even then they weren't very good!). The show does start off with a bit of a miss, Commander Blacky (yes that's his actual name) is incredibly boring but luckily he gets killed off and is replaced with Commander Zuril, who I like a lot. He plays off Commander Gandall extremely well, I might be biased though I was fujo-ing out over them quite a bit I wont lie. Commander Gandall is super cool too, he channels a bit of Baron Ashura energy as he has another personality in the form of "Lady Gandall" who I'm a big fan of even though she doesn't show up much.
Most of their scenes involve them sitting together at a table and discussing some sort of wild plan
Unfortunately the big baddie, Lord Vega, is kinda boring. Mostly due to the fact he barely has any sort of presence for most of it. Although there is a really interesting moment where Planet Vega suddenly blows up out of nowhere and this causes Lord Vega to have to evacuate, leaving most of the Vegans to die. It's actually a bit of a shocking and kind of an upsetting scene. If you've ever watched the 1986 Transformers movie, it's reminiscent of a very specific scene from that! If you've watched the movie you know what I'm talking about.

As the show nears the end, it begins to focus a lot more on family. They introduce Grace Maria Fleed, a very cute girl and the little sister of Duke Fleed! I really like her even though she unfortunately doesn't get a lot of focus. I like how she also feels a bit weird although in a different way to Daisuke. Right at the end they have some incredibly tragic episodes for the son of Commander Zuril and the daughter of Lord Vega. A lot of these episodes really moved me, Zuril's in particular brought me to tears and I found it genuinely extremely heartbreaking, it's a really good way to further touch on more of the war aspect and how innocents always get caught in the crossfire.

The art is great in this show, there are so many episodes that have consistently really beautiful backgrounds, especially the ones that take place in autumn, god it's so beautiful. The use of colours and shot composition are incredibly striking and purposeful and greatly enhance just about every scene. Characters look great too, they're drawn on model very consistently and I'm a big fan of the visual style too. The first half of the show has a real cowboy aesthetic and I honestly adore it, I'm pretty sad that they ended up moving away from it but it's whatever I guess. The animation itself is pretty great too although it didn't "wow" me that often, there were still some really cool moments and really well-directed action.

The music, courtesy of the legendary composer, Shunsuke Kikuchi, is fantastic. It is so damn good. Even though the track-listing is fairly small, I never got tired of hearing it. It feels really grand, really magnificent, fits the focus this show has on space super well. Special shout outs to the opening and ending themes sung by Isao Sasaki. Fly Grendizer! is an incredibly triumphant march, a song that represents Duke's duty to always fight and protect the earth. I particularly love the lyric "Even though the Earth is so small, it glimmers with Justice and Love" (that's my translation of it). The ending, King of the Cosmos Grendizer is beautifully nostalgic, it has an almost dreamlike quality, particularly with the choir in the chorus that makes me feel like I'm rising into space myself! My favourite lyric is "Even for a singular flower, Duke Fleed will risk his life", sometimes listening to this song makes me cry.

It's not without it's issues though, I think some of arcs tend drag on a bit and by virtue of being a 70s episodic show, there are a lot of plot-lines that would've greatly benefited from being two-parters instead but I understand that there were likely mandates in place that prevented them from doing that. It's easy enough for me to try and ignore that and enjoy the episodes on their own but there are moments where it feels really jarring, in the worst cases the episodes would wrap up incredibly abruptly after spending most of their runtime slowly building things up. By far my biggest problem with it though is that often times the writers change their mind about a certain plot element and deal with it in incredibly sloppy ways. There is a running issue throughout the show of an arm injury that Duke received during his planet's destruction, a fatal one at that. His arm is infected with "Vega Radiation" which is slowly spreading and may even reach his heart. He's basically fated to die sometime but they don't know when, it's clear that Duke was likely meant to die as there are a lot of signs and foreshadowing indicating that that's how things were meant to go. It re-contextualises a lot of his behaviour early on and you could even say him fighting was a sort of coping method. However, 4 episodes before the finale, he reunites with an old friend and sets his gun to "Radiation removal mode" and cures him immediately. What???? Genuinely baffling writing decision and an astoundingly stupid way to deal with that plot point. In the second half, a lot of the side characters featuring during the first half of the show take a major backseat as things get more serious but I do wish they found a way to balance it better.

The finale is great, they significantly upped the stakes and the semi-final showdown between Gandall and the Grendizer are really exhilarating to watch. I especially liked Lady Gandall fighting against Gandall, resulting in an attempted assassination of Lord Vega before Gandall takes over and kills Lady Gandall by shooting himself in the head, it reminded me a lot of a certain movie.... if you know you know! I will say the final-final battle with Lord Vega is a little anticlimactic, they take him out super easily it's kinda nuts. The show ends with Duke and Maria leaving earth and returning to their own planet, it's a very heartfelt goodbye and I cried a little... It was so beautiful.

All in all, Grendizer to me is an amazing show and I'm incredibly happy I finally sat down and decided to watch it. I'll be honest it's a bit of a hard sell being a 74 episode long show that's mostly episodic but if you're at all interested in it then you definitely won't be disappointed.

Let's all do our best for our beautiful green Earth!
