report Recommended by ZXEAN

In both series, the MCs have merged with a non-human creature - a Parasite (later named Migi) in case of Shinichi and the Chainsaw Devil (nicknamed Pochita) in case of Denji. Both the creatures fully merged with them during a life-or-death situation. Initially, Migi had only taken over Shinichi's right hand, but at some point to save his life from a fatal injury, it merged with his heart by donating some of it's own cells. On the other hand, Denji had already died before Pochita literally BECAME his heart to resurrect him. The MCs then have to fight against other creatures of the same kind they merged with. Both series also deal with the changing emotions of the MC and their sense of humanity. Both have thrilling fight scenes with outstanding animation. One notable difference is that Shinichi can't control Migi's powers on his own and has to live in a symbiotic relationship with Migi, whereas Denji has complete control over his Chainsaws. read more

"Kaiju No. 8" and "Parasyte: The Maxim" share similarities despite their distinct premises. Both anime revolve around humanity's struggle against monstrous entities: in "Kaiju No. 8," the world is threatened by giant kaiju, while "Parasyte" features parasitic aliens infiltrating human hosts. Protagonists Kafka Hibino and Shinichi Izumi gain extraordinary abilities due to their encounters with these creatures. Kafka transforms into a kaiju, and Shinichi develops enhanced physical prowess. Moreover, both series explore existential themes, questioning the nature of humanity and identity amidst overwhelming threats. Their narratives are characterized by intense action and suspense, captivating viewers with their gripping storytelling and exploration of human resilience in the face of monstrous challenges.

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.

Koutetsujou no Kabaneri addpermalink

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.

Monster addpermalink

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).

Gleipnir addpermalink

The main characters of both series are very similar. Both heroes have similar names (Shinichi and Shuichi), lose the need to use glasses, and start off as shy nerds and turn into cold fighters.

Both series also deal with an alien race coming to Earth and affecting the lives of the characters when they come into contact with humans, although in Gleipnir they are mostly in the form of inanimate objects.

Alien 9 addpermalink

Both have alien beings that form respective parasitic/symbiotic relationships with humans, the way these humans combat each-other is very reminiscent. The metal screw type protrusions of alien 9 as well as the bladetype things of parasyte and the way they are applied in battles are very similar. Both involve the main character entering this relationship with the alien against their will.

Death Parade addpermalink

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.

Claymore addpermalink

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 ...

Just like Mirai Nikki, Kiseijuu has a lot of gore and bloody scenes, the plot is original and the graphic is awesome just like Mirai Nikki. Both animes have unexpected turns of situation. Also, you may like that little drib of romance inside it that makes the character grow little by little.

Higurashi no Naku Koro ni addpermalink

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.

Anime: Fate/stay night: Unlimited Blade Works

Fate/stay night: Unlimited Blade Works addpermalink

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 F/sn: UBW has the superior animation by far.  While both have dark themes, the serious action is often juxtaposed with carefree, peaceful school and family life as well as romance. read more

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 and use their powers to fight off other evil alien monsters disguised as humans and both kills their enemies with gruesome attacks.
