They arrive in silence and darkness. They descend from the skies. They have a hunger for human flesh. They are everywhere. They are parasites, alien creatures who must invade—and take control of—a human host to survive. And once they have infected their victims, they can assume any deadly form they choose: monsters with giant teeth, winged demons, creatures with blades for hands. But most have chosen to conceal their lethal purpose behind ordinary human faces, so no one knows their secret—except an ordinary high school student. Shinichi is battling for control of his own body against an alien parasite, but can he find a way to warn humanity of the horrors to come?

Parasytes are an alien species that take over the human body by replacing the head. Our shmuck lead Izumi was about to be taken over by a parasyte, but due to some quick thinking he manages to stop the alien inside his arm, upon which the parasyte consumes his arm and takes it place. The two then have to learn how to live with each other while also dealing with all the other parasytes that have landed on earth.

What drew me to Parasyte originally was seeing the body horror pictures of how peoples’ bodies mutated and warped and started growing tentacles and teeth and occasionally read more

Alright, let's talk Parasyte:

STORY: Alright the story as described in the paragraphs above may sound cheesy and unoriginal to some, I know. However, as the story progresses the plot thickens and is beautiful. It shows how various people with the parasites, the bad not the good, try to cope in society and that's actually amazing to see unfold. One gets pregnant, one tries not to kill, etc.

Also, Parasyte shows quite vividly how someone would live with another symbiote in their body. Needless to say, this is very cool and interesting if you're in to that sort of thing. read more

"What's Wrong?" that is how this great voyage begins.

This manga is very good, his story is very original for its time, and shares many things with their similes of today as Tokyo Ghoul, the high school student who ends up inadvertently embroiled in a mess by a strange creature, the villains who want to exterminate mankind, but this shows us a more realistic way, and not just focusing on put fights, THE PROTAGONIST WANTS TO DO SOMETHING, no for example Kaneki, it wants save humanity on their own to prevent something from happening to your family and friends, which ends up happening, read more

Parasyte is a series written and drawn by Hitoshi Iwaaki. Unfortunately this is his only notable series so I can’t so much about his career. I mostly picked up Parasyte on a whim and also because my favorite manga reviewer, Y Ruler of Time mentioned it on his Seven Deadly Series list. But I digress, lets get started.

Story: The story is your standard alien invasion story. Little spores about the size of tennis balls fall from space and give birth to little worm like creatures. The creatures then invade the heads of humans and take over their bodies. The end result being that the creatures read more

Manga: Tokyo Ghoul
While watching the anime for this manga Tokyo Ghoul instantly came to mind. To avoid spoilers i'll just say both main characters are in some what similar situation in addition to their personality transition.

Manga: Devilman
Both stories involve creatures which take over people's minds and bodies and can morph them in monstrous ways, and a protagonist who manages to retain his human personality despite being one of these hosts. Both protagonist's have to deal with this fact while keeping their identity secret and struggling not to lose their humanity.

Manga: 70 Oku no Hari
Those familiar with Parasyte would view 7 Billion Needles as something of a rip-off, should they read it. An eccentric alien entity comes from outer space, merges with the lead and slowly-but-surely comes to be friends with its host, as they battle together against other alien enemies. If you're experienced, you've read it all before.

The first two volumes aren't bad - the characterisation being solid enough - but the last two turn it into a nonsensical mess that would most likely leave you with a desire to have re-read Parasyte instead.

In terms of the 'merging' itself, 7BN has more in-common with  read more
