At the dawn of the twenty-first century, a sudden climate change known as the Equatorial Winter devastated humanity. The survivors saw the new age as an opportunity to create a unified world order. Driven by this vision, the United Nations officially declared a war to determine which country would become the first world government, a war they named the Wisest World War. This conflict would be carried out not between soldiers but between individual mecha known as Gigantics. In such a restless world lives Shingo Suwa; he has just beaten hundreds of candidates to the position of pilot for Japan’s mecha – the Susanoo. But there is far more to the Gigantics than meets the eye. Is Suwa truly prepared for what it takes to fend off all the other champions and bring victory to Japan?
In the future, a devastating event known as Second Impact has destroyed Tokyo as we know it, giving rise to Tokyo III - a city under siege by mysterious lifeforms known only as Angels. Mankind's only line of defense are the Evangelions, a set man-made machines piloted by a trio of fourteen year-old teenagers, Rei, Shinji, and Asuka. The fate of Japan and the entire world now lie with these three children, though they might not have the power to save the most important thing of all: each other.
Both Gigantic Formula and Evangelion have a city that sends children to defend mankind and its faith. If you like that sort of thing, these are the anime series for you. Though Neon Genesis Evangelion was made in 1995, the concept behind it is similar to Gigantic Formula, which has children piloting large mecha to save the world!
Both of those animes have for main character a teenager boy, who have to choose between fighting to protect people or to let it go and do nothing. Both mechas are connected with their pilot, they have a conscience too, pilot and mecha make one, which is likely the same in both animes. There is differences in characters between those to series, that is what make Evangelion a bit gloomy and Gigantic like an optimistic atomsfear. Enjoy both :)
It is hard not to draw comparisons between Gigantic Formula and Neon Genesis Evangelion. However, many of the comparisons I can make contain spoilers. I can say that both are series that have children fighting in giant robots to save the world, where said robots have their own secrets that are slowly revealed.
Neon Genesis Evangelion gets more existensial, serious and mind bending than Gigantic Formula. So if you are looking for something a bit weirder and thinky, try NGE. If you want something more simple, try Gigantic Formula.
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!
If you liked the 'more beneath the surface' treatment of the mecha, the symbiotic mecha-pilot relationship, and the 'impending apocalypse' feel of Gigantic Formula, then you will find these elements presented in an even superior way in Eureka Seven. In many ways, they share a similar tone - not least provided by the cheerful child protagonist in each.
The mechas and pilots of Eureka Seven and Gigantic Formula have several similarities. Nirvash and Susanoo are more than traditional mecha, having wills of their own and responding to the will of their pilots. Mana and Eureka act as translators (to steal from Gigantic Formula) for the mecha's will, while Renton and Shingo provide the determination to protect people.
If you enjoyed the symbiotic relationship in Gigantic Formula and want to watch something with a much better overall storyline, I wholeheartedly recommend Eureka Seven.
When a group of children discover a strange cave at the beach, their lives are forever changed. Inside they find a hide out filled with computers and a man named Kokopelli who gives them a curious offer: to participate in a special game in which they save Earth from fifteen giant monsters. To defeat the invaders, he will give them a powerful mecha of black armor. The children eagerly sign the contract, name their new weapon Zearth, and must now take turns to pilot it; but the 'game' is in fact all too real and the consequences of battle become the stuff of nightmares. With no option to cancel the contract, is there any way to stop the game before it is too late for all of them?
I'm making this a one way recommendation, as I loved Bokurano but had serious issue with the pacing of Gigantic Formula. The premise of the two stories is quite similar - young school kids piloting giant mech to save the earth/their country. Bokurano is much darker and has a sense of impending doom for its hapless pilots, carefully exploring their life before they sat in the robot Zearth.
Both have tales that can be quite saddening, but I think Gigantic Formula fans will enjoy the more twisted way Bokurano is handled.
In a possible future, mysterious devices called plates create robotic "Antibodys": Brain Powerds, or Grand Chers. In this world, a monumental structure known as Orphan lies at the bottom of the sea, slowly making its way to the surface to fly into space; however, its success would result in the death of every living being on the planet. Already, natural disasters are prevalent due to its ascension. In order to stop Orphen from obliterating humanity, the organization known as Novis Novah uses Brain Powerds to battle it, while Orphan searches for more plates and defends itself using Grand Chers. In the middle of this war is Hime, a girl who found and mastered a Brain Powerd on her own and joined Novis Noah, and Yuu, a boy who has served Orphan all his life but now decides to escape and fight alongside Hime. Can these two young people make a difference in this war? And what is the true purpose of Orphan?
Both Brain Powerd and Gigantic Formula use mechas that aren't quite of the traditional formula. Rather than big stompy super powered mechas piloted by brilliant individuals, the mechas in this series have minds of their own. Indeed, the mechas in these series actually choose their pilots to a degree and react to their will and feelings.
In addition to the above, there is a similar story line in which the characters are trying to forstall an event that might result in the destruction of the world, caused by the very beings they pilot.
It is my firm belief that if you watch both of these series, you will find many similarities and an equal level of entertainment.
Far, far away in a distant time, there is a tribe of people called the Golden Tribe who have the ability to create stars and foretell the future. They gave out a warning to those who have yet to mature: 'Move.'. Three tribes answered their call: the Silver Tribe, the Bronze Tribe, and the Heroic Tribe. Soon after, the Golden Tribe encountered a crashed ship in which only a baby human known as Age survived; they named the child's race the Iron Tribe and assigned one of the few living members of the Heroic Tribe to protect him and his race. Now, in a distant part of the galaxy, humanity is threatened with extinction at the hands of the other tribes. With only a prophecy to go on, they set out to the deepest depths of space to find their savior named Age -- humanity's last hope.
Heroic Age and Gigantic Formula seem quite familiar to me. Sure, they both involve caring boys who pilot giant robots. Sure, the ties between robot and pilot are much closer than many series. But it goes a bit beyond the surface similarities I feel.
I can't explain it better than that. I can only suggest that if you liked one of these series, you should give at least a few episodes of the other a try.
