If you're looking for a series about brotherhood, then both series would have to be the best recommendation as both tell a tale of the bonds 2 brothers have and the trials they go through. Whilst both series may be of different plots, what they both share is the highly-packed action and spectacular graphics.
Even though it's a bit too early to tell, the relationship between Rin and his brother Yukio seems to be a major theme of "Ao no Exorcist," as is the importance of Ed and Al's bond in "Fullmetal Alchemist: Brotherhood."
Ahhh... Brothers, the most intimidating relationship that is a little mysterious but appreciatively amusing and mature. Both series sets off a dejavù experience of brothers battling their way to survive after the death of someone precious to them. In FMAB, Ed becomes a state alchemist right away but in AnE, Rin takes on multiple steps to achieve his goal. Both shows have something going on their respective institutions. Plus, the characters are quite the same. Ed and Rin, being the older brothers are quite a handful when it comes to sticky situations. They easily get mad and erupt their emotions quickly. Al and Yukio, on
Both shows are about two brothers and their relationship as they struggle to accomplish their goal.
Although their storylines are quite different, Ao No Exorcist and Fullmetal Alchemist: Brotherhood have similar themes of brotherhood and semi-scientific special abilities. I found that the governmental structure and the moral intricacies were explored in similar ways, encouraging the viewer to question their understanding of these elements.
-Story about two brothers
-Their mother is dead
-Their father isn't human
-Both are really enjoyable and worth watching
Brotherhood is a very strong theme in both FMA: B and Blue Exorcist. There's also a fair bit of action and comedy to keep you laughing the rest of the time. There's no doubt that if you like one, you will enjoy the other.
Both have dark undertones, stories of brotherhood, a decent-sized cast (though Brotherhood has much more time to expand its number of characters) and a MC with some serious daddy issues.
If you liked Blue Exorcist's short and sweet fight scenes, mysterious villains and complicated family relationships, you are sure to like both FMA and FMA: Brotherhood as long as you are willing to commit to a longer series. Trust me, it's worth it.
I don't know how to explain what's similar between these two animes but trust me, if you liked FMA:B, you will like Ao no Exorcist. The story line in both of these animes give the same feeling/vibe.
Two brothers with supernatural powers, team up against evil forces. However, Ao no Exorcist has less drama and more silly moments.
Both have comedy and action both are great for new comeings and vetrens alike both are great starters [ao no exorcist was my first anime] both deal with whats right and wrong have some sought of magic or power both can be very depressing
brother + great dialogue + trust me you'll like them.
A tale of two brothers who love each other to death, have a sad past and live in a world of fantasy. AND they have a female friend they've known for a long time.
Both the animes are surprisingly similar and I'm shocked nobody has yet been able to make a connection between the two.
