Why do North American fans say Kai has no blood in it?

Why do a lot of people on youtube keep saying that Kai is the kiddy version of DBZ and that the show has no blood in it?

Because a lot of the more casual fans are not aware of several things that regular Dragon Ball fans are. I don't look down on them, as there is no law stating that people need to be familiar with the various English dubs of Dragon Ball-related shows. However, there are nevertheless many, many casual fans who are not informed of several key facts. Namely...

-That the versions shown on Nicktoons and the CW4Kids/Vortexx are edited.
-That there is an uncut home video release of Kai available (and FUNimation has not helped that cause by failing to mention in all of their commercials for Kai that it is uncut on home video).
-That the Toonami airing was edited.

Because Kai is visually edited on the TV networks that air it, the more casual fans make the assumption that everything about Kai is a censored, edited effort to make the show more watchable for younger audiences, including the dialogue.

The best thing you can do is politely explain that there is an uncut home video release with the blood they are used to and much more mature dialogue than the original DBZ dub ever had. Some will doubt you (I had one fan accuse me of making it up), but others won't. I've converted a few people into Kai fans by pointing this out.

Lool I tried to explain to some of them but they just won't listen.

If you tried to explain it to them then you know why people say there's no blood in it. I mean, if you can truly fully understand why it's edited and you are in fact explaining it to people who say this, then... yea, you know why...

By the way, Tanooki Kuribo, for whatever it's worth, thanks a lot for making that Nicktoons edit guide. I've found it very interesting myself, but I bring it up in this thread because that guide has also served as a very convenient educational tool for me to point fans to to demonstrate that stuff was edited (and, for that matter, what specifically was edited). Nice work!
