Shows like parasyte -the maxim-

Parasyte (Japanese: 寄生獣, Hepburn: Kiseijū, lit. "Parasitic Beasts") is a science fiction horror manga series written and illustrated by Hitoshi Iwaaki and published in Kodansha's Afternoon magazine from 1988 to 1995. The manga was published in North America by first Tokyopop, then Del Rey, and finally Kodansha Comics. The manga has been adapted into two live-action films in Japan in 2014 and 2015. An anime television series adaptation by Madhouse, titled Parasyte -the maxim- (寄生獣 セイの格率, Kiseijū Sei no Kakuritsu), aired in Japan between October 2014 and March 2015. The English-language dub aired on Adult Swim's Toonami block in America between October 2015 and April 2016.

Parasyte centers on a male 17-year-old high school student named Shinichi Izumi, who lives with his mother and father in a quiet neighborhood in Tokyo, Japan. One night, strange worm-like creatures with drills as a 'head' called Parasytes appear on Earth, taking over the brains of human hosts by entering through their ears or noses. One Parasite attempts to crawl into Shinichi's nose while he sleeps, but fails as Shinichi wakes up, and enters his body by burrowing into his arm instead. In the Japanese version, it takes over his right hand and is named Migi (ミギー), after the Japanese word for 'right'; Tokyopop's 1990s English version, in which the images are flipped horizontally, has the Parasite take over Shinichi's left hand and it is named Lefty.
