Three separate versions of the same story, plus a Korean series set in the same world that tells a different one.
Start with the 2014 anime. It is the complete story, it is the best regarded version, it is widely available, and finishing it makes every other entry on this page legible. There is no real competition for the top slot here.
Seen some of these already? Tap the circles to tick them off. The full list below fills in as you go.
Twenty four episodes adapting the manga from the first chapter to the last, including the ending. The setting is modernised to the 2010s with smartphones and the internet, and the character designs updated, but the structure is faithful.
Ten volumes, the same story, better paced and shorter than it looks. Kodansha began a new black and white English edition in 2025. Pick this or the anime, not both.
Six episodes, an entirely new cast, and a premise re-explained from zero. Watch it after the anime and the final two minutes become a payoff instead of a stranger walking into a room.
Then what? The two Japanese live action films are the weakest entry point. They compress the same story into under four hours, cut the parasites Kana and Joe entirely, reduce Shinichi's family to a single parent, and change the mechanism used against Goto. Watch them after the anime or the manga as a curiosity, and know that starting Part 1 commits you to Part 2, because Part 1 does not resolve. Parasyte: TAMIYA is due on Netflix in 2027 and is not listed here, because its episode count, its date and its position on the timeline have all not been announced.
A suggested way in, not an official one. The full list is below: tick anything off in either place.
Everything you tick is saved in this browser and nowhere else. An account is the only way to put your list on another device, and the only way to get it back if this browser clears its storage. It is free and it takes an email address and a password.
Sign in on your phone, your laptop, anything, and the same list is there, kept in step as you tick. Nothing to copy, nothing to remember.
All three are about this franchise and all three are for showing, not moving. The link and the picture open SagaList with that progress displayed next to whatever the person opening it has already ticked. The code is what a friend pastes into Compare below. None of them writes anything into anybody's list.
Read only. This never changes what you have saved, and nothing leaves your browser. The code has to be their code for this same franchise: codes do not carry a name, so one from somewhere else may not be recognised as wrong.
Removes everything ticked here, in this browser. If you are signed in it clears on your other devices too. If you are not, there is no other copy and this cannot be undone.
Your email is confirmed and your account is ready. Everything you tick is saved on this device, as it always was.

Your SagaList account.
Nothing else happens until you follow the link. If it has not arrived in a few minutes, look in your spam folder and search for SagaList. It is sent from a no-reply address on our own domain, so there is nothing to reply to.
Both addresses get an email: the new one to confirm it, and the old one so that nobody can move your account without you knowing. Nothing changes until you follow the link.
Signing out leaves everything you have ticked on this device exactly where it is. It only stops it syncing.
This removes your account, your email address, and the progress stored on our side. It cannot be undone and we cannot get it back for you.
Nothing is charged and nothing is cancelled, because SagaList does not take payments. What goes is your account, your email address and the progress synced to our side. What stays is everything ticked in the browser on this device.
