ok it's time to explain the real meaning of Doujinshi.
The word "Doujinshi" thought to be a japanese drawing style used by bleedman, is actually the japanese word for "fan comic" or better put as "comics created by fans of the orignal comic."
as boring as that seems, it's the truth. the reason bleedman is actually allowed to make Doujinshi PPG, is because of that word...."Doujinshi" and the copyrighting to Genndy and Craig creators of ppg and Dexter's laboratory.
pretty much , with that being said. pretty much anyone can make a doujinshi comic. even american style fan comics are sometimes referred to as Doujinshi.
many people even work together using a website such as facebook or fanpop to work together on a comic. one person can write the script and send it to the editor through messaging, then have the editor send it to the artist to draw it out, then have the artist put up the inked in drawing, have the color artsist color it, then have it sent to the lettering person. sometimes to make it easier on the amount of people, one person is the writer and the artist, while another is the editor and the last person colors, adds word baloon, and adds the text to the comic.
so that's the true meaning of Doujinshi! hope ya liked it!
I just wanted to make that clear
