In the 24th century, the planet's fossil fuels have been completely consumed, forcing humanity to use solar power as the primary source of energy. A huge solar energy system orbiting the planet was eventually built, anchored to the Earth and providing it with power through three orbital space elevators. As a result of the expense of such a large-scale project, most the world consolidated into three factions: the Union, the Human Reform League, and the AEU. Despite their common reliance on the fragile orbital elevators for energy, however, humanity still continues to constantly fight wars and build up arms. A paramilitary organization called Celestial Being, equipped with incredibly powerful mobile suits called Gundams, fight in order to force humanity to unite and eradicate armed conflict.
Half a year has passed since Sousuke Sagara took up the job of protecting Kaname Chidori and has started living like a normal teenager for the first time. A former child soldier, his view on the perils of everyday life is highly unconventional and in frequent need of violent adjustment; Kaname can only hope her endless assault will eventually get him used to normal life. But a shadow looms over their happy days as Sousuke's employer, the private army called Mithril, is attacked by a new unknown enemy. Suddenly outgunned, can Mithril afford to keep one of their best playing around?
While both Gundam 00 and FMP do have mecha battles, they are even more similar in the main characters. Both Sousuke and Setsuna grew up in the midst of fighting and war. This gives each of their characters a unique outlook to the world. So, I think with a mix of action, militaristic combat, and similar main characters, you would enjoy one if you liked the other. Be aware that FMP has comedy/romance while Gundam 00 does not.
In the future, Earth is split into three factions: Dorssia, an empire bent on world domination; ARSUS, a military alliance; and Jiro, a collection of neutral states with colonies across the galaxy. On one such colony, Haruto Tokishima lives a carefree life at Sakimori High, where his greatest concern is mustering the courage to confess to his childhood friend, Shouko. His idyllic life is broken, however, when a team of Dorssian super-soldiers, led by the enigmatic L-elf, assaults the colony to retrieve the 'Valvrave', a mobile suit secretly being constructed there. In the resulting chaos, Haruto watches as Shouko disappears within a laser’s blast; enraged, he climbs into the now accessible Valvrave, and defeats the Dorssian army after forsaking his humanity to the machine. Haruto pledges to protect the colony, but can he come to terms with what he's given up to gain such power?
Both anime a similar in few aspect as great mech fighting scenes, some character development and involvement in nation conflicts. Though Kakumeiki Valvrave have a "lighter" tone that Gundam 00 and story goes aroud school drama. While Gundam 00 takes itself more serious with involvement of politics and deeper character struggles. If you watched one I recommend to watched other one or at least give a try and don't be afraid of Gundam 00 just ,because Gundam franchise is so wast. Don't worry you will not lose anything since Gundam 00 are in different timeline that others Gundam anime series.
There are numerous similarities between these two, but most apparent ones are obviously outer space conflicts, mecha action, politics and the cast of charachters. With some simialr plot devices, charachter progression, these two could appeal to the same kind of audicance, so if you liked one, you might like the other one.
Two and a half years have passed since the end of Naruto’s old adventures. He has trained hard with Jiraiya-sama and has returned to Konoha to reunite with his friends; but Akatsuki, the organization that threatened Naruto years before, is on the move again and this time Naruto is not the only one in danger. With the powerful Akatsuki organization looming ahead of him, Sasuke still missing, and the struggle with the beast hidden inside him a continuous battle, will Naruto's hard-earned improvements be enough? Join Naruto, Sakura, new friends and the rest of the old gang as the action heats up with new techniques and stronger enemies.
The conflict between Akatsuki and the shinobi nations is similar to Celestial Being and the 3 power blocs. There are also moments that are funny, light hearted, and dark but at the same time there are deaths involved as well that will bring impact on the characters and the plot.
