You can download W.I.T.C.H comics for free from Invision Free.
This section of the site is dedicated to all things W.I.T.C.H, so you will have fans uploading their favourite comics and making requests for those they do not yet have.
Remember, though, that this is not an official site, so do not assume you can trust everyone on the message boards.
You do not need to become a member of the site to access the comics – they are uploaded to the message boards, but if you want to comment, upload some comics yourself or communicate with any of the other members, you will have to register.
Be sure to read through the policies of the site so you do not end up getting yourself banned from the forum (I know some people who have had this problem in the past), and enjoy reading your free W.I.T.C.H comics.
