Answers for your Questions. The reason characters such as Plas, Shield, and Blackhawk have not been included is because of policy. If MadmikeyD decides to change policy then the characters could be added to the wiki, but until that time they will not. Sherlock Holmes is included by the way since he has been used by multiple companies and individuals without permission from the Doyle Estate in America. Overseas copyright is different. Comic Strip characters who are in the publis domain are more than welcomed to be added to the site as well as Natty Bumpo, the Deerslayer. Wonderman is in because there is no active trademark and his one comic appearance in Wonder Comics #1 was never renewed. Captain Marvel while some of his appearances are public domain many were renewed and he is actively being used by DC comics. Tarzan also is trademarked while many of his books are in the public domain. Also, I do not know what comic appearances he has made were not renewed.
