- both shows have protagonist’s that are mostly child-to-teen like that shares a common deep, secret pasts and are trying to liberate an area from foreign rule.
- both season have more lot of intense, factional plots and counter plots more than their prequel's.
- both have a faction that vying for control of different groups trying to exert their will on the grand picture of things.
- both anime ended with a similar stereotype ending and epilogue.
Both continue where their respective previous season left off in a serious and more involved plot this time:
-The story focuses on a group of young people fighting for freedom against a superpower faction vying for absolute control.
-Mysteries surrounding the mecha are revealed
-Deaths occur out of nowhere and spread like crazy
-The series end in a similar fashion that wraps up the story
-There is no happiness but tragedy
The only difference is that Valvrave is the reconstruction of the tropes deconstructed in Code Geass and Gundam IBO continues the trend of 00's deconstruction of the Gundam tropes.
It is an odd recommendation but I can't help but see Blues EXE being similar to Vidar due to the same VA and both are mysterious individuals who are rivals with the main character. Both are cartoony in some way but have serious moments as well and Rockman has a history of having elements being influenced by anime such as Gundam for example.
Both shows are considered to be the darkest and depressing of the franchise. What both have common:
-Post Apocalyptic Setting
-Science and Technology
-Powerful Protagonists who overcome their invincible enemies
-A lot of bodies dropping as the show progresses
-Do not expect it to end happily ever after
When watching Mikazuki in his Gundam, I get a lot of Guts vibe from him making me think that IBO is inspired from Berserk. Both of the shows encompasses political and realistic themes but the only difference is that IBO has mechas and Berserk has warriors and supernatural powers. Another note is that Mcgillis shares the same VA as Griffith and both are Char Clones.
