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.

After finally being transported to another world full of nature and endless battles, Zed soon comes to realize that his life of purpose has just begun.
In both of those animes there are some things that must not be brought together or some sort of a disaster will occur. However those things are still brought together. Also the main characters do not relay on their own strenght alone. They have been blessed with an extra "soul" that belongs to them only and makes them so strong. Both of those animes also have different worls and planets, between which the characters often have to travel. However Kiba is more of a medieval style anime, while Heroic Age is sci-fi. Kiba still holds some of the sci.fi elements too. If you liked one of them I suggest you check out the other one.
When Akito Tenkawa went looking for answers about his parents' deaths, he had no idea that he'd be indoctrinated into the spaceship Nadesico not only as a cook, but also as a mecha pilot – a job he wants nothing to do with! Alongside his childhood friend Yurika, stoic Ruri, otaku Gai and other misfit crewmates, Akito and the Nadesico crew find themselves in the middle of a brutal war against both the dreaded Jovian Lizards, and the military itself, who wants the civilian ship under their control...
Both set in space, the middle of a war between the humans and an unknown alien race immediately starts the similarities in these series. While Nadesico takes the path of comedy, and weaves a story that while funny still creating serious moments, Heroic Age, does the opposite creating serious moments with parts of comedy. Both tactics work and if you enjoy the space adventure of one ship against an entire fleet, then you'll definately enjoy watching both of them.
On the eve of nobleman Oz Bezarius's fifteenth birthday, he and his loved ones gather to celebrate in a coming-of-age ceremony. But after Oz steps under a long-stopped clock and the hands finally move once more - thus fulfilling a mysterious prophecy - he is violently thrown into the legendary prison known as the Abyss by three cloaked intruders. Existing in another dimension, the Abyss is home to lifeforms born within its walls known as Chains; these beings can only live in the real world if they make contracts with humans, binding their power to the person's body. However, there's a catch - in time, the human will be overcome by the Chain's power and then thrown into the deepest level of the Abyss. When Oz wakes up in the Abyss he is quickly attacked by hungry Chains, only to be saved by one named Alice - a Chain who appeared just before he was thrown into the prison. Together, the two make a contract and return to the real world, where they are enlisted into the Pandora organization - a group researching both the Abyss and the trio that threw Oz into it. Along with members of Pandora, the duo searches to find Alice's lost memory fragments that are scattered throughout the world, to discover the secrets of the Abyss, and to determine if there's a way their contract can be broken without killing either Oz or Alice.
What Heroic Age and Pandora Hearts have in common are mature, responsible protagonists with a special and well designed universe. For Heroic Age, that universe is one filled with monsters with the power to destroy a world, inter-stellar warfare, and space opera drama in a grand SF adventure. For Pandora Hearts, the setting is Alice in Wonderland complete with a uniquely Japanese look at the matter, with a dual dimension setup to divide one world from the other.
For those that loved the deepness and character strength present in Oz Bezarius and the cast of Pandora Hearts, surely you will also come to appreciate the great design work on the cast of Heroic Age. It works the other way as well.
It's been a thousand years since the Gauna, a strange alien race with no known method of communication, destroyed the solar system. A portion of humanity managed to escape using enormous "seed ships" like the Sidonia, which have allowed them to maintain the population while drifting through space. Nagate Tanikaze is a young man who has been raised deep in the bowels of the ship. When he goes into training to pilot the huge robotic weapons known as Gardes, Nagate is entrusted with piloting the legendary unit known as Tsugumori. Nagate and his fellow pilots put their lives on the line against the Gauna, in the ultimate battle for the survival of humanity.
Humanity is floating in space endangered and only one mecha pilot can save them. This premise of Heroic Age is repeated in Knights of Sidonia, although the latter does a better job with it. Knights develops less cartoony characters and presents a more hard sci-fi world that will appeal to the more mature viewer. Granted, Knights' animation, which is all glassy CGI, is probably less easy on the eye. But if you want to see Heroic Age done in a more grown up manner, you will like this show.
Long ago there was a battle between angels and humans, which ultimately ended with the angels’ retreat. Twelve thousand years later, the angels have become active again and have begun harvesting humans for nefarious purposes; and only the pilots of the ancient mecha known as Aquarion are able to oppose the angels' tools of war. The pilots have special powers, but the secret to defeating the Angels once and for all lies with the reincarnations of the two beings who defended humanity against the Angels in the past: Apollonius, an Angel who turned his back on his kind in order to protect humanity; and Siren, his human lover. Only Apollonius can awaken the true strength within Aquarion that is needed to defeat the angels; but who is the reincarnation of Apollonius?
A lot about these two animes is similar. The themes are similar--the human race is fighting to protect themselves. The aura is similar too, you get the same feeling watching them. The protagonists are both 'barbarians' that suprise people with their power. There are differences, as with most animes, but I think that you'd like one if you liked the other.
