If you enjoy one you're likely to enjoy the other. Both great quality. Both about a male lead who has part of his humanity taken away without his consent. Both main characters go through a few similar things. The fighting in both series doesn't vary much, with Parasyte being a bit more tactical / realistic, and Tokyo Ghoul being a bit more over-the-top.

Two very different treatments of very similar themes, those themes being large-scale questions of human moral responsibility. Parasyte weaves these themes into a more intricate, tightly constructed plot, whereas Devilman addresses them with much greater pathos. If you enjoyed one of these series for its philosophical, moral themes, definitely check out the other.

These shows have characters with unique powers. The experience is fresh and not something seen before in other anime. The story is quite dark, innocent people die and the story is mature and realistic. And the best of all is that you always want to see the next episode. Sometimes there is so much tension that I have to stop myself of reading the manga to find out what happens.

Ajin is the new Sei no Kakuritsu in my opinion because, the key about these two series is the suspense. Kei reminds me about Shinichi in some ways like :The poor main character who wants a normal life but, BOOM something comes on and change his entire life. Also,while Shinichi has Migi, Kei has his phantom or whatever it is.

A foregin life form invades human society and starts infecting the population. Faced with thes alien creatures, the lines between man and monster, and good and bad start to shift. While these shows quite differ in characters and atmosphere (Shiki is a dark fantasy/mystery and Parasyte is more sci-fi and action oriented), both ultaimtely tackle same, age old question: What makes a human human and what differentiates us from animals/monsters? Parasyte goes one step further and gets a bit enviromental, questioning man's relationship with Earth, but not in an annoying, preachy fashion.

Both shows: *Produced by Madhouse. *Main characters are accompanied by a being that is outside of their ''normal'' world. *Main characters hide their secret from everyone else. *People having ''mysterious deaths'', although the causes are different in each show. Although there are many differences, they are both great if you enjoy series with good quality and dark undertone.

Both series involve a glasses-wearing main character being infected by a strange virus/being that threatens to take over their mind. However, in the nick of time, they manage to keep the intruder out of their bloodstream and save their humanity by cutting off their own circulation and blood flow to the brain. As a result, they are now half-bonded with whatever wanted to take over their entire body, giving them a unique set of powers. Both series are packed to the brim with blood, gore, horror, and action elements, set in worlds where humans aren't at the top of the food chain.

In both shows, the main character gains gruesome superpowers that he doesn't want, and said powers end up changing their entire lives.

What the 2 have in common, both involves the same MC whom where a half of a monster that has given them a significant amount of power to fight their own kind, except in TG the MC is somewhere being with the good guys and bad.

Midori is the EVEN MORE bizarre romantic equivalent to Parasyte's grotesque parasitic broship. They present the same problems - namely, how it's too awkward to masturbate with a talking hand - but go about them in very different ways. One involves a lot of death; the other involves a lot of love. The 'hand' in Midori is more like a female talking hand-puppet that JUST HAPPENS to be joined to the lead's arm one morning when he wakes up... and is the girl the lead has a crush on, ofc. On the other hand, Parasyte has a transforming alien life-form that, initially, had every intention  read more

Two competing factions battle for survival. In both of these series it is humans vs some kind of perceived monstrous being. However, soon you realize both are simply vying for survival, an instinct every creature has. This further blurs the line between good or bad. Although I think Shinsekai yori does an immensely better job at this than Kiseijuu does, there are parallels and in the end you wonder who is the real monster.

Well,these both anime has a creatures seems as a normal human but actually they're a monster that disguise as a human (Yoma in Claymore and Parasyte in Kiseijuu). (sorry, bad english) And then, the MC in these both series are a half-human and half-monster which in Claymore some people are like that too. Both series are have a Violence, Gore, and Horror inside which Claymore is most likely very very darker and more gore than Kiseijuu .. Yeah, if you like the one,you will like the others ...

If you like mature and dark animes like Parasyte, I would suggest Monster. Like Parasyte, it is a great horror and seinen anime. It is a little different than parasyte as it is not about supernatural beings but about a serial killer. Monster is also by Madhouse Studios (the same studio that is making Parasyte).

Both of these anime are about young people that are suddently infected by human-consuming parasites/viruses. Both anime involve quite a bit of blood shed, questions arising concerning the protagonist's human-status, and some of the strangest characters you will ever see in anime. So, if you liked one, try the other.

In both animes the mc's starts out as an wimpy kid kinda, while as the show carries on they become more badass and gain a lil bit of personality change. They are also about aliens..giving them a similar atmosphere.

Both anime have humanity facing enemy which tends to be a new perfect species, and main character finding himself in the middle them. On first look he is both of them, but actually not any of them. Anime asking questions like what is it to be a human being? And what future have a life?

A teenage boy has an alien living inside of him. The alien sometime causes him to say/do perverted things. The alien causes him to act strange in other ways, such as at school and at home. The girl the MC has a crush on thinks he is a pervert because he did/said something perverted to her/in front of her.

In both anime, the main protagonist has a symbiotic partner with their hand. D has Left Hand and Shinichi Izumi has Migi. Left Hand and Migi have their own unique personality and has a bond with the main character. They are also horror action-packed anime with blood and gore. Both titles are also animated by Madhouse. The difference between the two is that Parasyte has aliens while Vampire Hunter D: Bloodlust has vampires and other monsters. If you enjoyed one, you will enjoy the other.

People trying to live with another strange creature with transforming like characteristics and having them battle with their own kind, though the overall tone is drastically different. You can consider the end of Cencoroll as a reference to Parasyte.

Both centre around human-like monsters that are going to exterminate humans. Even though elfen lied is more tragic, they have a similar atmosphere and equally entertaining fight scenes

Both of them are horror anime with their main strong point being the plot. The gruesome killings from the Kiseijuu can also be found in Higurashi or even more. There is another strong resemblance with Kiseijuu but it's a huge spoiler so only those that watched Higurashi will understand.

Both anime have something that is hidden within the human which emerge and leave a bizarre scene. Is it evil? I don't know. The main villain can sometime feel similar too. Bio Hunter is more mature and leave many questions unanswered but is worth watching if you are not looking for a great anime or a masterpiece.

Both titles are based on sci-fi manga from the 1980's. Both focus on the main protagonist who is merged with an alien power that gives superhuman abilities. The main protagonist in both anime use their powers to fight off other evil alien monsters disguised as humans and both kills their enemies with gruesome attacks. The differences between the two is that The Guyver is more superhero oriented while Parasyte is more psychological horror. If you like, you should enjoy the other.

Both main characters are thrown into a battle involving the supernatural, and must fight in order to protect innocent people who are inevitably caught up in the conflict. Both have to deal with moral dilemmas of what is right and wrong, how far should one go to protect strangers, and the purpose to fight. In both anime other characters challenge the MC's way of thinking, as every character attempts to progress his or her agenda by killing his or her enemies. As both anime are action anime, one would enjoy both series for their great fights and duels between either servants or parasites, although  read more

Both anime focus on characters who are not 100% human and are suddenly thrust into a kill or be killed situation, with not many options as to who to trust.

Just to get it out of the way: this 'recommendation' would get a tad technical if it focused on arm loss. In the manga, Kurokami's lead, Keita, loses his arm at the start and has it replaced with someone else's as part of a life-saving contract. In both Parasyte's manga and anime, its lead, Shinichi, also has his arm replaced by another lifeform. So, a superficial similarity exists. HOWEVER, this becomes confusing due to Kurokami's anime being a bastardised version where, instead of arm swapping, HEARTS are exchanged. And in Parasyte... /spoiler ...but I'm not here to compare the two based on arms/hearts. That would be  read more

Being in the world of parasytes and being in the world statis draws similar feelings of isolation and dread. Art: The dark grungy atmosphere and presentation of the animation are almost the same. Sound: Both have amazing opening themes that are inspired of metal rock and electronic disco.

Both products often have scenes in the main character's family house. I don't know exactly how explain it, both products gave me a strong sense of the human social life and they showed me his beauty. I can understand that the similarities are a bit tiny, but I was unable to ignore the strong vibes of Aku no Hana that Parasyte continuously gives me.

The stories both revolve around highschool students wich follow the goal of protecting humanity and their loved ones from the antagonists of each series. While they have some in common they do have some in uncommon, like the love story between Shinichi and his girl, a love story that isn't in WorTri but a story of Osamu doing all he can to protect Chika wich is like a little sister to him.

Both shows are about understanding, or at least trying to understand others (humans and humans or humans and arbiters in Death Parade, parasites and humans in the case of Kiseijuu). Excellent execution in terms of art style, animation, and sound for the two shows. If you've seen one, then you have to watch the other so as to gain more perspective on the whole coexisting and mutual understanding concepts both share.

They are both done by studio Madhouse. They share many of the same genres: Psychological, Sci-Fi, Action and Seinen. They have a very similar art style too in my opinion. Also, they both have some brutal death scenes and are overall fairly violent. The main characters in each anime did not want to be put in the situation they are in. Finally, EVERYONE WANTS TO KILL THE MAIN CHARACTER!

"Parasyte" and "Another" feel very alike to me. Not only are they both horror anime, but Kouichi feels a lot like a slightly younger Shinichi- nice guys who are initially a bit of a wimp but overtime gain a strong resolve to protect the people close to them and do what's right. Migi and Mei both initially appear to be hostile and start off as cold and distant but slowly warm up to Shinichi/Kouichi, and generally go unseen by most people. In a way, Mei fills the roles of both Migi and Satomi, being not only Kouichi's closest ally but also his love interest. Ultimately, while both  read more

If you are like me, then you enjoyed Ao no Exorcist for the overall concept of the show. I love the idea of a character struggling with an inner evil that they had no control over receiving, so they must keep their struggle a secret. Parasyte deals with a wimpy teen who can't figure out what is wrong with his hand, until one day he jumps out into the street to save a little girl from getting hit by a car, and he suddenly sees an eye and claws grow out of his hand that completely stop the car in its tracks.  read more

I never gave much thought about the similarities about two shows after i rewatched them twice. In fact, they have an internal similarity about: "two minds sharing one body" and "how it works out for the two characters". Sounds interesting? It should. :) Anyways, Kiseijuu has some gore elements but Hikaru no Go is quite light-hearted in that matter. Both shows are quite deep in the relationship i mentioned earlier. If you are interested, check them out, both are very well written stories.
