Blassreiter

If you equate the Contractors with the Demoniac, everything else falls into place. 

Most of these anime's elements are the same. The only differences are mainly the time, country, and weapons used. These Anime both are about demonic outbreaks that only need to be resolved by te main character who has mastered the power to controll the demonic side of him/her. 

Heroes who are given powers against their will go to war with the faction that provided them power. Both of these shows have so much in common it's not funny. 

-Very similar plots -Bad childhood -Main character is a monster that fights other monsters. 

Both have a main character who has a special power that has them transform into a super powered humanoid being. Both main characters focus on saving those with special powers like their own.  

They both seem pretty similar in the design of the armor. 

Both animes are very similar to each other. has action bloody and the fight scenes are very similar. Also like Karas, they put there suits on instantly and start fighting other demons... 

Blassreiter and Elfen Lied both have very sharp similarities and invoke intimate drama. These animes include mass murder and apocalyptic views which should intrigue the cynical soul. However, Elfen Lied is more inclined to female killing machines while Blassreiter offers humanity itself becoming these machines.  

Both MC's are fighting against something that takes control/eats humans and makes them into something demonic. Both main MC's are owners of special bikes and given special powers. Both transform into a mecha-like being. Blassreiter is a bit more dark than Garo.  

They feel almost identical. I can't reveal too much without spoiling Blassreiter. 

Both anime have loner main protagonists and they both have a bad reputation. They start off hated and end up doing good for most people. Blassreiter is completely underrated whereas black cat isn't, but both are great shows. 

both shows have people who transform into cgi demons, fight with swords.. masses of people die, elements of bullying/discrimination/suicide plot revolves a 'saving humanity /humanity has fallen' lots of death.. 

An inner demon is present in both series that the MC must control. As the episodes progresses, there is emotion and drama. Also, supernatural and cyberpunk themes are present in both series that reflect a dystopia like setting. Of course, saving humanity is another theme in both series. 

Both series were created by Gonzo and offer similar-looking 2D and 3D animation. These TV shows are of the sci-fi genre, featuring edge-of-your-seat (and often over-the-top) action sequences of 3D mechs and/or starships. 

Both main character's are working to atone for the sins of their families(Joseph for his sister and Domon his father) so they strap on mechanized armor (or become it) and fight to save their world. Another series where the faith of all other characters rest on the protagonists shoulders. 

Both anime have themes of religious mythology ( Saint Seiya Greek and Blassreiter Gnostic/Christian.) Both have instances where the faith and powers of all of the other heroes are placed in the main character to defeat a big bad. Seiya is a little less dark but still has its somber moments like most early anime. 

Young man turned into a demon like creature and gets cool armor.  

The death of a beloved family member sets two men on different paths. One wants to control everything. The other wants to stop him. 

Both are about transforming superheroes who are mis understood and fight their own kind, with apocalyptic and biblical themes abound. 

Christianity provides important themes of the story. Both are dark, introspective and emotionally moving. They also are both set in alternate reality Europe, albeit in different time periods. 

Both cyber body horror stories. Main character is given nanite virus that threatens to destroy the world. There are secret societies and fast paced fights in both.  

sad as he'll story about a hero injected with a serum that brings back the dead. Both fight said reanimated dead and seek to stop the plans of the one who betrayed them. 

in both there's people who can transform their bodies to gain superhuman strength and abilities, and a law enforcement organization that supervizes them. both main characters are good guys accused of crimes they didn't commit, who have no choice but to go against said organization to survive, while trying to deal with the actual culprits at the same time. 

The female main character is in a way similar, and there is alot action in them, but the main reason might be, similarity of the character styles. i recommend both, dragonaut has a light style, while blassreiter has dark style to it, but for you to think more than boring of these serie, you have to watch more than one episode. 

Different feel similar themes. Misunderstood demon(niac) being fighting against his own kind for the sake of humans and for revenge on an enemy from their past. Both are trying to prevent the land from being over run by evil creatures. 

Another Nitroplus anime that has the same level of drama, without the mecha. Both involve a secret powerful organization, and both have a reluctant tragic hero. 

Again, just like Blassreiter, this anime is very serious, fast paste, and has its unexpected plot twist.  

Delicious human mutation involving super powers with some nice graphics. Mysterious rival with similar power, and a lot of monster butt kicking :) 

In terms of religious belief, it is very similar. In Claymore, the Silver-Eyed Witches who are the saviors of humanity are considered the same as the enemy demons by the civilians, whereas in Blassreiter, Joseph the Blue Demoniac is considered the same as the berserk Demoniacs by Team XAT. Thus, there is a clear relation between Clair of Claymore and Joseph of Blassreiter. Aside from that, the battle scenes are also very similar, except that Blassreiter features CG in some of the scenes, whereas it does not occur in Claymore. 

Like Blassreiter, Gundam 00 has a lot of action and is a fast paste anime. Both animes are also very serious and have plot twist that you would never expect. 

In both the earth in chaos, and humans try to survive in the middle of wars. They´re both set in a near future and are about science experiments with humans that went wrong causing confusion and destruction.  

Similar feeling because, if the users with the super power/magic have weak mental health or abusing the power to much, then they are turning into "demonics" or demons, which are similar. Both have pretty much gore and action too. 

Both shows deal with the main character having super natural powers (including a transformation), and fighting against the people with similar powers. There's plenty of twists in the plots in both shows, so if you enjoyed one of them then it'll be the same for the other. 

both animes have vast storylines with amazing character driven stories. the main grows into himself in both animes while the anime itself shows the problems that other tertiary characters have to deal with. both create a great anime that is fun to watch, blassreiter is a bit more dark and has stronger themes that E7 but both still share alot of similarities 

Brilliantly choreographed fight scenes feature in both these anime 

Just look at those "superbikes"... both are just the same :) . Fights, extreme races and breathtaking action... but the story is quite different. 

The animation on Blassreiter leaves a little to be desired, but the stories are similar. The lone hero fights against the injustice of their own kind to save humans. In both cases the hero's story is where it all began. 

Both shows have some common things There are cases that human infect with nanomachines and become more superior The main villains Ashley in Solty Rei and Xargin in Blassreiter are good at first and then become evil. Both have good motive but end up using evil way to achieve personal goal. 

Both involve battling with the "inner darkness/demon/beast" or whatever you wish to call it.  

The animation on Blassreiter leaves a little to be desired, but the stories are similar. The lone hero fights against the injustice of their own kind to save humans. In both cases the hero's story is where it all began. 

Anyone say robot zombie apocalypse? Both of these shows have 'em. Do I need go on? 

Both anime involve the main protagonist that can transform into a powerful monster humanoid being that must fight against monsters that threatens humanity. The main protagonist both in Blassreiter and Devilman have to struggle to control their inner demon while trying to keep their humanity intact. They are also both action-packed anime with lots of blood and violence. If you like one, you will enjoy the other. 

Both anime has the main protagonist that get superhuman powers through another entity and over time he must learn to fight with it. The main protagonist in both Blassreiter and Parasyte must struggle to control their inner monster while keeping their humanity intact. They are also action-packed anime with a similar dark and gritty atmosphere filled with violence and blood. If you like one, you will enjoy the other.  

The infection in Blassreiter that allows them to fuse with bike and become bioweapons is similar to Xam`d.In Xam`d u will also see a biomecha(Human Forms) and a hunting force to hunt them just like the Blassreiter.The heroine initially joins the hunter team and then sides with hero!! :p
