Both shows take place in a post apocalyptic setting featuring mecha that are of god-like proportions. Both of them also feature psychological aspects and religious symbolism(although it only has meanings in Big O and not Evangelion).
Both series features science fiction themes with the involvement of mecha in combat warfare.
Both series features a style of old school art that are nostalgic. There is also action, drama, and some psychological themes especially involving some of the later episodes and plot.
Both series takes place in a post apocalyptic setting that also explores some religious themes.
Both shows have very similar mech designs, fight choreography, and characters. They also both have a similarly dreary tone and a psychological mind-bending plot. However, I feel that Eva gets a bit darker as it's story goes on, while Big O just gets more cryptic and enigmatic.
It's futuristic in nature and has the same "overcast", melancholly tone to it. The characters are increadibly similar to eachother;
Spike Spiegel and Roger Smith (both voiced by Stephen Blum in English) are both cool and collected characters with beloved allies that annoy them to no end.
Faye Valentine and Angel (both voiced by Wendee Lee in English) are both selfish women looking to restore their lost memories and who become unwillingly in love with the main character.
Both these series are anime with a style that's more similar to American cartoons than anime itself. CB has its cowboy aesthetics, while Big O is often described as ''Batman turned anime''. They also share a strange, offbeat but at the same time melancholic atmosphere that's further enhanced by a jazzy soundtrack. If you liked one, then I strongly recommend giving the other a try.
Both series contains a similar feeling with the main male protagonists being tough, independent, and collected. The main female protagonist from both series also has similar traits.
Both series gives off that old school vibe with the jazz music and solid OST.
Both series follows an episodic format with its themes.
They both also have great dialogues, action, and drama, and science fiction themes.
This one should be obvious. Not only did they air around the same time, but they also have the same studio and neo-noir feel (though "Big O" is more of a mech series than a western). The characters are also very similar:
Spike===>Roger- Both are very laid-back, slothful, sarcastic people who often get annoyed by their allies but obviously care for them regardless.
Faye===>Angel- Both have amnesia and are highly selfish, manipulative and seductive women who end up having a highly belligerent relationship with the main character.
Jet===>Dastun- Very similar appearances, and a close but professional relationship with the main character that dates back several years. You could argue that Dastun is what Jet WAS like when he was still a cop.
Imo, "Cowboy Bebop" is better than "The Big O" in pretty much every aspect, though there's still some enjoyment to be found in the latter. read more
The Big O has so much references to Giant Robo, that you could think that they are both set in same universe. Actually, this is pretty good explanation for... oh, wait, no spoilers. But the atmosphere is completely different: Giant Robo has a classical "superheroic" plot, and The Big O is very close to noir drama.
Both shows are set in bubble cities in the near future and have some dark vibes. While Ergo Proxy doesn't have mechs, its does still have some action packed combat. More importantly the characters in both stories delve deeper in the history and dark past of the bubbles cites to reveal some big secrets.
Both series are based in somewhat distopian worlds. Ergo Proxy is quite desolate world, where The Big O is just a little distopian (think Mad Max and Blade Runner in comprarison). Ergo proxy is more of a drama and psychological exploration, where The Big O is more stylised as a crime noir drama, even show design is based in 30´s america. Both are action based but with heavy dramatic scenes and quite significant character development. The Big O animation seems little old by todays standards, but given design of the show I think it is not that much of a hindrance.
Both are about lost memories. However The Big O features a mass memory wipe, while Cassher Sins is only limited to Casshern.
Both of them however, feature a dystopian future due to a past cataclysm. that took the lives of many and are the result of the protagonist's memory loss.
Big O and Darker than Black draw influences from film noir (and, some may say, Batman). Both are set in a grim future brought about by a cataclysmic event that occurred years prior. The protagonists are well-known professionals in their line of work with shady pasts that may be connected to the aforementioned disaster.
Both shows are heavily inspired by the aesthetics of western media at the time (Bubblegum Crisis with Blade Runner and The Big O with the Batman animated series). They both also follow a more episodic approach at the start, with a few somewhat standalone episodes of the cast solving crimes and fighting enemies, before moving into a more connected storyline in the latter parts.
Both start out as mecha shows with fun and sometimes outrageous scenarios. As they progress though they begin to show their true colors. While Code Geass questions why we lie and mask our true selves and whether it's a good or bad thing to do, Big O asks why our memories are so important to us and what would happen if we lost them. Both show corruption through god-like power (Geass and Mega Deuces.) Code Geass's mask symbolism is similar to Big O's stage symbolism. While Geass is all about Zero planning out his attacks and putting on dramatic "performances", Big O does the exact opposite as it's characters are pulled along by the play. Both shows were made by Sunrise. read more
Suave renaissance men who have mysterious pasts pilot larger than average mecha with help from classy butlers and capable female companions. The mechs are the selling point of the shows, but both main characters are skilled inside and outside of their robots. The plots are mostly episodic. The Big O is more serious, but has a sly sense of humor. Whereas Daitarn 3 is very comedic with occasionally dark undertones. Lots of fun.
- Strange futuristic world.
- Cool-headed guy and female robot buddy.
- Both robot girls are very strong and most definitely lift more than you.
- World building through episodic adventures arising from their freelance work.
- Sinister overarching plots.
- Robots and laser beams.
The robot girl from Dimension W is more or less a cheerful moe-blob human and the robot girl in Big O is colder and has a drier, more deadpan sense of humour. The protagonists are also 'badass' in slightly different but equally neckbeardy ways.
The Big O was memorable for its narrative depth and exploration of human values and morals, and while it did break away from this with its occasional robot smash up moments, this was what made the show as good as it was.
Psycho pass takes the narrative elements that The Big O occasionally dables in and refines, focuses, and directs it more clearly and gives a lot of insight and thought into the complex issues of free will, human nature, and the value of law and freedom. If you enjoyed how the Big O would take a moment to make you think, you'll love how Pyscho Pass gives you a season to make you question everything you've ever known. read more
The Big O's Roger Smith is pretty much Bruce Wayne with a super robot as opposed to a Bat costume. Much of the production staff behind The Big O had previously worked on outsourced animation for Batman TAS, taking much influence from that particular iteration of DC's rich superhero. Batman: Gotham Knight is a simply a more direct anime version - just from some different talent and an alternate anime studio involved.
Haves the futuristic and most importantly the Gotham City feel. Paradigm City is like Gotham City without Batman, but with gundam like mecha. Metropolis has the large city feel, with its run down slums and power hungry elites. But both shows, have a past of these cities that's surround in secret.
Roger Smith and Reiji Fujita is very similar to each other and they both have a similar job. On top of that they both have a female assistance to help them in their work. The bond between them will also get close as the story develop.
The themes and the settings may be different to Gallery Fake, however as I remember Big O have a seinen type of story which someway is similar to Gallery Fake.
Both have that spy-fiction feel that reminds us of James Bond. To support that feel, they both have creative character designs; some good to look at and some ugly as sin.
They also have very good music composers who make those action scenes as groovy and smooth as a sarsaparilla(it's a rare drink, but it's good!)
They're basically moody shows, that are easy to take in, since they have American characteristics.
Big O has mecha, has an overarching story, has much better animation despite it's age, and has a strong message.
009-1 is orchestrated in a stand-alone manner, making it a bit harder to enjoy. It's character designs are also a little harder to swallow. And it also contains graphic content. read more
Have very different characters and style but somewhat similar stories and settings in the sci-fi genre. They both take place in a post-apocalyptic world, No.6 in a city built to be a utopia with a wall to keep the rest of the world out, and Big O in Paradigm, a city where the rich live in domes, and few know about the cities outside. Both settings have dark secrets the main characters must uncover, and in doing so learn more about themselves.
Both have strong American superhero influences. Big O is full of Batman allusions, the main character being a rich man who dresses in black and uses gadets to poke around and solve mysteries (and fight mecha) and the art style is reminiscent of the art-deco type animation of the old batman cartoons. Tiger & Bunny is a bit closer to X-men with characters who are NEXT with powers are considered 'the next stage in evolution' by some and people to be feared by others, with some NEXT turning to crime and others turning to heroism. They both also take place in urban environments highly similar to American cities.  read more
Both Lupin III and The Big O have this old-fashioned animation style that looks about the same. Although, Lupin has a different storyline, but I see the similarities in both Lupin and Roger, they are (not) detectives, but you know, they have the feeling they want to be one and then act towards being one.
They're both pretty fun to watch although The Big O has a more Sci-Fi feel to it while Lupin has this dramatic-comedy feel to it. Both are enjoyable and decent to watch.
