"Parasites" are tennis ball sized creatures, whose numbers and origins are unknown. They invade and take over the human mind in order to survive. Shinichi Izumi is a 16-year-old high school student who lives with his parents in a quiet neighborhood. One night, a Parasite invades Shinichi's body in an attempt to take control of it. However, it fails to complete the takeover process and ultimately ends up inhabiting only his right arm.

Thus, both Shinichi and the Parasite—who calls himself Migi—retain their individual minds. Now in a peculiar "human and alien" relationship, Migi proposes that they cooperate to survive. Shinichi has no choice but to agree, and he must now cling to his morality as he and Migi face off against other bloodthirsty Parasites.

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

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

They control the body by invading the brain. They can change the shape of their bodies and use them as weapons. They eat humans.

Like a logical continuation of John Carpenter's The Thing (1982), set in modern day society and with more than one parasite, Parasyte is an entertaining sci-fi horror thriller.

Descending from the sky, parasites fall onto humanity. They worm their way into humans, penetrating skin and then act erratically before eating whoever is around them. As the story begins, a parasite fails in its attempt to infect a teenager, Shinichi, who becomes the protagonist. The thoughtful and quick-witted guy 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
