Well... This is pretty easy.
Both character designs are by Katsuhiro Otomo. But that's not all. Both anime have this "Future/Cyberpunk" feeling I love. The main characters are similiar to each other and both have many future tube-like racing scenes that catch your eye.
- Character designs are very similar, since they are done by same person (Katsuhiro Otomo)
- Street races (Bike race in Akira, Hovercraft race in Freedom)
- Breathtaking background art
- Main character, where both of them preferring modified vehicles, and has tendencies to go all-out for friends
- Sci-Fi settings with advanced technology
Drawn by the same animator, Freedom and Akira are on different ends of the mood scale. While Akira is very dark, moody and mind-screwy, Freedom is upbeat, positive and still somewhat mind-screwy. Also, the best advertisement for Nissin Cup Noodles I've seen since a CG'd Freddie Mercury.
Well, they both take place in space....They also deal with a futuristic world where humanity is dealing with problems that were brought on by past generations. They share the same sense of exploration in the story and have a head strong lead character. Also, did I mention that they both take place...IN SPAAAACE!!!
READ---> Both take place in the post-apocalyptic time strain, both are about a grandiose journey in which many truths are uncovered. Both are about a civilization living in a life support dome, under severly strict governmental rule, and both have strong routes in human will and the need for freedom and the truth. There are many more small similarities that you will pick up as you whatch these as well. If you've seen one, you'll love the other. Trust me.
Both series feature a post apocalyptic setting where the remainder of society has been diverted to domed cities. The protagonists each set out on unique journeys outside the domes that lead them to uncover key points about the plot and world they live in. Although the domed cities boast strict government and rife technology it's widely desolate outside of them.
Ergo Proxy carries a heavier tone than Freedom, and is the more developed story of the two. Freedom is short and easier to follow, but has noticeably less depth. If you've seen one you will probably enjoy the other. Regardless, they present similarities.
Both anime have almost identical setting. Main characters obsessed with similar thing, in case of Pale cocoon it's video with girl and earth and in freedom it's photo of girl and earth again. All in all anime have different ambience but except of that they practically identical.
Protagonists from space have been told lies by their government about the planet Earth and the fate of humanity there; they travel to Earth and find humans living cosily in the post-apocalyptic Earth. Some cultural clashes ensue; moreso in Gargantia since Ledo is a soldier whereas Takeru and his friends are underground racers.
Both involve molluscs.
Both series explore a similar concept of a post-apocalyptic crisis warranting Earth uninhabitable, and the surviving humans seek a new home in outer space. Both series' viewpoints are from a space-dweller's whose whole perception of Earth is grounded on the fact that it is uninhabitable, and the protagonist discovering that there is more to Earth and life on Earth than what the upper echelons of authority in their society suggest. They also share the visual dichotomy between the environments and inhabitants of Earth and the metallic confinement of outer space and their respective inhabitants.
Patema Inverted is a lot like Freedom.
Both of their plots can be summed up as; two human civilizations are separated from eachother after an apocalyptic event and pretend the other doesn't exist. Journeys between the two worlds, a photograph and an ambitious project that ended in disaster will have serious impact...
The setup and feel is very similar.
In Patema Inverted there are Agia and those that live underground. Agia is a police state disguising itself as a utopia where the characters there are drones except for a select few. The underground is dark but cosy.
In Freedom, the technology superior civilization is the Moon, including Eden a police state similar to Agia. The government there would like everybody to be drones but the characters we see don't play by the rules and nor do their rivals. Eden is like Agia but there are also areas of the Moon like Freedom ward that has the cosy atmosphere of the underground in Patema Inverted.
On Earth, the remnants of humanity there live in the ruins with a society similar to the underground in Patema Inverted.
The characters of Patema Inverted really reminded me of a mix and match of Freedom characters. Age is surrounded by the memory of his father similar to Ao, the heroine of Freedom and Patema is motivated to visit Agia due to a photo similar how a photo motivated Takeru and Bismarck, the protagonists of Freedom, to visit Earth. However, Takeru and his friends are also similar to Age because they constantly rebel against the government. read more
While almost 20 years apart in creation, both feature space colonization plotlines, and high production values, young people (mentored/taken in by an older male) on tri/mono/motorcycles who get embroiled with opposing factions in some sort of larger scale conflict. There are also aspects of political critique that emphasizes the differences in 'freedom' on the colony and the Earth.
If you like the post apocalyptic setting of Freedom where humanity lives within a very constrained existence, you will probably enjoy Shingeki no Kyojin. It's not a space drama, and there really aren't any other similarities with characters or art, but both main characters are on a quest to live freely beyond the tight limits humanity has set because of apocalyptic-like events (think Gurrenn Lagaan).
At first we can see the (lunar) city where people live in peace and boredom, until main characters don't discover the truth about their society. They seek FREEDOM for themselves and righteousness for the population. For that, they need to escape from The City. Sounds familiar, ne?)
Both animes gives a same feeling as they both contain hope, surviving and luck etc. There are also similar events in the plot. I think you will like them both, however Planet Survive have cartoon style of graphics and more of the sci-fi genre which can may make it less good.
People living on the moon because the Earth has become uninhabitable and a relationship between a boy from Earth and a girl from the moon. The moon is ruled by a totalitarian government that restricts information and individual freedom.
Both involve humanity having shifted from a dying Earth, to live seemingly ideal lives in space. Both involve strained relations between people living freely on Earth and those in a strictly controlled utopia in space. Both involve confident protagonists who visit Earth and later try to change the way things work, back in space.
Both also use similar styles in animation and character rendering.
Both also have fairly simple plots that don't require a lot of thinking to get into.
The main difference is that, while Freedom's sci-fi elements are largely grounded in reality, Expelled from Paradise goes full-on sci-fi, complete with mech battles and sentient AIs.
