New York Time best seller Squirrel Girl say HI.
A character collecting dust and then got a OGN that was a best seller.
The book shelves are filled with unknown characters that find audiences.
As for profitable-if DC was to bother to **********you will make more money with Signal and Batwing because you have a book market that ignores black boys.
And as many writers have told me that is a market ANYONE if they bother to put EFFORT in can control.
Right now Marvel is going after it with Miles.
And the secret to get a profitable book is to use writers that folks KNOW. Not just pander to entitled comic book fans who would love for Duke to not exist.
