Fourteen years ago, an environmental disaster known as the "Hammer of Eden"” devastated the planet – taking with it six billion lives, and submerging 90% of the world underwater. In the present, the remaining countries have formed a new United Nations in hopes of peace. Gould, a submarine captain, wishes to use military force to obtain this goal, while Aoi, the secretary general of the UN, believes in the power of diplomacy. In this world, Keel and Teen are twin siblings who, through a series of events, travel separately with Gould and Aoi. Together, they seek to answer the same question: is war the only way to attain peace, or can people learn to set aside their differences and negotiate?
Like most boys his age, the young Renton thinks of nothing but reffing – riding trapar waves on a board – and idolizes Holland, the leader of the renegade group of reffers named Gekko State. As an orphan of a famous hero, he lives a boring life with his grandfather until the beautiful Eureka crashes, literally, into his life. Now, with the help of his newfound friend and crush, Renton finds himself living amongst the crew of Gekko State. The errands are hard and the bullying is fierce, but with Eureka by his side, Renton just might find the courage to tough it out and even save the world!
Not only do both anime deal with main characters who are suddenly brought onboard rebel ships. Both protagonists in Eureka Seven, and Tide-Line Blue are trying to figure out what they want, while trying to persuade negotiation rather than war. If you like one, you will like the other.
The main actors of Tide-Line Blue (Kneel) Eureka Seven (Renton) are very similar and mentality and appearance. Both are involved in a romance. Both stories are about avoiding war.
It is the year 2267, and all that is left of humanity now lives in the 'Eden colony', a domed metropolis on the moon. Earth has long since been abandoned after a cataclysm left it uninhabitable... or so the inhabitants of Eden are led to believe. But when a young boy named Takeru discovers a photograph of a girl which appears to have been taken on Earth, he begins to doubt that this is the case. With the help of his friends, Takeru decides to visit Earth in search of the girl; despite the fact that it is against the strict laws of the colony and despite not knowing what awaits him there...
Both titles are set in a future after Earth undergoes a devastating change.
Both are adventuresome set in the future.
Both titles are not heavy hitters in the realm of dark or brooding, but more along the lines of hope in mankind's future.
Tideline is more along the lines of Waterworld for earth cataclysm, and Freedom is more Logan's Run, for people living life in a dome. This said however, if you liked one, you might enjoy the other.
Once upon a time, two brothers passed the happy days of their childhood by studying alchemy, which is governed by the equal transfer principle: an eye for an eye -- you can't get more than you give. But these brothers tried to defy that law, and a horrific accident resulted. Now, the older brother, Edward, is called the Full Metal Alchemist because of his metal limbs, and the younger, Alphonse, is a soul without a body, trapped within the confines of an automaton. Together they search for the power to restore themselves, to find the lives they lost so long ago...
Not only do the main characters in Fullmetal Alchemist, and Tide-Line Blue look very similar, the theme of each anime are also very similar. War, government corruption, and main characters who are willing to oppose authority are central to each. Both anime ask the question, how far are you willing to go to get what you want. If you like one, you will like the other.
Thor and Rai are twins who live on an advanced space colony called ‘Juno’. Things take a nasty turn one day when they are kidnapped by the Federal Army’s Special Forces and abandoned on the hostile prison planet Chimera. A cycle on Chimera consists of 181 days of scorching heat and 181 nights of below-freezing temperatures – not to mention it is populated almost entirely by carnivorous plants. The convicts on Chimera have found only one means of survival – reverting back to the law of beasts. For the strong-willed Thor adjustment comes naturally; but for his naive and weaker brother Rai, things do not go as well. Thor must now use all his wits, strength and courage to endure life as a member of Chimeran society, rise above the rest, and take the only ticket off this planet: becoming the Beast King.
Twins? Sci Fi? Yes.
If your a fan of a set of twin boys being sent from a life in space to a planet full of challenges, this is the title for you.
Both have a good amount of action, and a lot of exploration of the planets in which they are sent.
In the near future, Mars is covered with oceans. Within one of its cities, Gram River is just another kid trying to survive in the slums, until he finds himself right in the middle of a pirate attack! After nearly drowning, he finds himself aboard the pirates' ship, and is faced with a decision: be killed, or stay and fight alongside them. And thus, Gram joins the pirate crew in their quest to find the legendary treasure of Mars, but they aren't alone in their search. Now, while being hunted by the military, bounty hunters, rivals and even a few old friends, they search the seas of Mars for clues...
If you like either Mars Daybreak or Tide-Line Blue you'll likely enjoy the other one too.
Both have a military aspect to them, have lots of underwater battle scenes and nice character development.
While Mars Daybreak takes place on Mars and Tide-Line Blue takes place on Earth they both tell a compelling story that makes you want to watch the next episode.
I liked the Tide-Line Blue ending a little better because it was more believable whereas Mars Daybreak was a little more in the realm of science fantasy rather than science fiction.
