Notes: Sometimes referred to as Joe Higgins, Jr. There is some dispute as to whether or not Bill and Joe, Jr are the same character. Some people believe them to be two different sons of Joe Higgins, the original Shield, and they both took up the mantle at different times. However the appearance of Nancy Zenith in stories attributed to both Bill and Joe, Jr indicate that they are one and the same. The 'Real Name' section of this profile offers a suggestion for the cause of the confusion.
