Welcome to a world in which memories can be transferred from body to body; old painful memories can be removed and replaced with new ones, and the poor sell their bodies to the rich to survive. Waking up one day, Kaiba finds himself in a strange place with no memories of his past and a mysterious hole in his chest; the only clue as to his identity is a locket with a picture of a girl hanging from his neck. Armed with this token, Kaiba must now travel across the galaxy to discover who he is and what the girl in the locket means to him; however, his journey will bring him into contact with many people whose lives have been tragically affected by the manipulation of memories. All too soon it becomes clear that something is very wrong with this world…
Although at face value, Kaiba seems to be nothing like Code Geass, what with its older animation style and very unconventional art style, Kaiba is a story diving into many levels of mystery and drama.
The main story revolves around the character Kaiba, a young man (not a little boy!) who has lost his memory, waking up in an unfamiliar place, not knowing just who is his friend or enemy.
Lelouche in Code Geass is also a teenager (with the maturity of a young man) thrown completey out of his royal element much like Kiabe was, and wrongfully exiled through gruesome means.
In each respective story, both young men have to find out what's going on in their universe, realize whom they've become and learn, along with the help of true (and fake) friends how to overcome thier plight, the results of which could save or destroy the very existence of their kind.
Both set in sci-fi world.
Both shows are trying to tell the watcher, that you can have everything and rule the world, but at the same moment you would have nothing.
Both main characters, Popo and Lelouch try to defeat current rulers of the world and take their place. In order to do that, they lose their friends and family.
One night, Madoka has a terrible nightmare – against the backdrop of a desolate landscape, she watches a magical girl battle a terrifying creature, and lose. The next day, the teen's dream becomes reality when the girl – Homura – arrives at Mitakihara Middle School as a transfer student, mysteriously warning Madoka to stay just the way she is. But when she and her best friend Miki are pulled into a twisted illusion world and meet a magical creature named Kyubey, the pair discovers that magical girls are real, and what's more, they can choose to become one. All they must do is sign a contract with Kyubey and agree to fight witches that spread despair to the human world, and in return they will be granted a single wish. However, as Homura's omen suggests, there's far more to becoming a magical girl than Madoka and Miki realize...
Both of these anime delve into the idea that often, great power comes at a price. With brilliant storytelling and plenty of psychological drama, these series are very much alike.
The main similarity between both Code Geass and Madoka Magica is that the plots invovle characters entering into contracts with mysterious contractors to obtain great characters. However, upon obtaining these powers the characters eventually fall prey to the powers that they have obtained. The situations of both Lelouch from Code Geass and Sayaka from Madoka Magica are comparable to one another since both characters enter contracts to obtain special powers, only for them to learn the truth behind their contracts, try to use powers that isolate them to help people, and eventually fall prey to their powers. While the plots are different, the reason why if you enjoyed one you'd like the other is that the two plots share similar themes, and are both serious takes on usually non-serious genres (the mecha in Code Geass and the magical girl in Madoka Magica).
Ten years before Shirou Emiya's and Saber's fateful meeting, Japan is the stage for the fourth Holy Grail War. Seven Masters, each with his own dreams, step forward to win the boon of the mystic relic. Into this fray comes Kiritsugu Emiya, the enigmatic "Mage Killer" who wants to use the Grail to make a better world. Can he, paired with the indomitable Saber win the War? Or will he fall to the ambitions of the other mages?
Both of these series involve loads of chracters making intricate plans against each other for various motivations. There is action and a supernatural element in both. Code Geass has a lot of high school age characters while Fate/Zero mostly involves adults, and there are more not-so-serious episodes in Code Geass. Code Geass has mechs while Fate/Zero has swords and sorcery. But they both have more plotting and gambits than you can count. If you like that aspect of one, you'll almost certainly like the other.
There are similarities between the two shows. While I would say Code Geass is better than Fate/Zero I wouldn't say that it is better by a landslide. Watch. Enjoy.
Later Space Cowboy
Hakaze, princess of the Kusaribe mage clan, has been betrayed and marooned on an island by her own people. They seek to revive the Tree of Exodus, an incomprehensibly powerful entity of alien origin, to save the world from the tyranny of its antithesis: the Tree of Genesis that powers their magic. Hakaze, however, believes their efforts put humanity in jeopardy; and with her power limited, she can only reach out to the world to beg for aid. Her call reaches Mahiro Fuwa, a young man grieving the mysterious death of his sister, Aika. He and his friend Yoshino agree to help - on the condition that Hakaze track down Aika's killer with her magic. The deal is made, and the battle that will determine civilization's fate is begun: but who will play the part of its villain, and who its savior?
They're both great animes with dark themes where the protagonists fight to right an injustice and an almost brother/rival relationship between the two male characters. They have complex characters where motivations are not always clear cut and events can turn the story on its head.
The characters are also similarly somewhat haughty and arrogant (CG - Lelouch, ZnT - Shakespear quoting lolita complex guy) anti heroes. I liked Geass a bit better due to its length but Tempest has a much more satisfying ending imo. Enjoyable animes both.
They're both almost post-apocalyptical anime, where the characters have to fight with everything that stands in the way. Code Geass is a bit more dramatical, things take a curious turn, while Blast of Tempest involves more mystery, magic and the fate of the world is in stake. Both anime show the fight for power and try to bring up the negative part in that and how hard can it be even if it is for the right cause.
Haruto and his comrades continue to fight against the forces of Dorssia. However, many things remain unanswered in the midst of battle, including the past of L-Elf and his fellow soldiers' past, the destiny of the mysterious girl Liselotte, and the feelings of Haruto, Shōko, and Saki. The relationships and loyalty of each and every member of each army will be tested as the clash of ideals and power reaches its climax.
With so many similarities in setting and plot devices (In both anime, the MC received a supernatural power, and many more), these two represent each other quite well. Both are mecha anime that play on a really big scale, featuring a huge cast of characters stuck inside a war between two nations. Packed with action, politics and supernatural, it’s pretty clear that those two draw the same kind of audience. If you liked one of these two, then there’s a good chance you might like the other one.
They both take themselves WAAAAY too seriously. The 2nd seasons escalate solid, if somewhat, convoluted plots to insane levels of stupidity.
I like both series, but you should try and focus more on the action and characters (some of them anyway), otherwise you'll just get annoyed.
