After his debut in 1,000,000 Years Ago (St. John, September 1953), Tor immediately went on to become one of the first comic book characters to star in 3-D comic books. The second issue of that series was renamed 3-D Comics before being renamed Tor with issue #3 in May 1954. At this point the series was once again in the traditional two-dimensional format. This series lasted until issue #5 (October 1954).
In 1959, Kubert and inker Carmine Infantino unsuccessfully attempted to sell Tor as a newspaper comic strip. The samples consisted of 12 daily strips, reprinted in six pages in Alter Ego #10 (1969) and later expanded to 16 pages in DC Comics‘ Tor #1. DC Comics would publish the Tor series for 6 issues from 1974-1975.
