Some Manga and Anime are for kids, but not all. Pokemon and Digimon are for kids. Nothing really bad in those. One Piece, Naruto, Bleach, etc. are for Teens. Some of the violence can get bloody. Death Note, Junjo Romantica, Aki Sora, Older Teens to Adults. It really depends on the rating the authors put on the back. BUT, some kids read them anyways. I've seen my friends 4 year old brother play Call of Duty: Zombies countless times. Yet, not one Swear Word or Violent comment comes out of his mouth. It's either the Authors opinion or the parents opinion.

It depends on what comic books,anime,or manga the children read or watch. If a child picked up a watchmen comic book no you wouldn't want to read that comic book many things in their are disturbing. If you they read Naruto or watch Naruto then I would let them watch it because Naruto is really not that bad there is only fighting and talking and some blood but not that bloody.

if you read any comic book, you will see how adult it is, and know that they are not for children. however, though i like the adult aspect, i still prefer a book that is almost certainly more intellectually challenging.

What about Comic Books such as The Watchmen? That is a very deep intellegint book --

Well there are many comic books that are for all ages. There is also some that are not. It really depends what the child is interested in and what the parent would allow them to read. For kids that are 10 a good comic for them to read could be a Spiderman comic. For 12 or 13 perhaps a Batman. If you would want a comic for humor purposes you could read a Flash, Spiderman, Plastic Man, and many more. So it really depends on the child and what they are interested in. If you wanted your child to read politically correct morale values you could let them read a Captain America or a Superman.
