Each issue our hero encounters characters from a different comic strip/book genre!
This time, he aids a space-going adventurer not unlike Flash Gordon or Buck Rogers.
Despite the blurb, this was Comics McCormick's final appearance in Terrific Comics, due to the book's cancellation.
His next appearance was a single story in Cat-Man Comics #28, then he joined Ed Wheelan's other strips in Fat & Slat, an EC Comics anthology title dedicated to Whelan's work that lasted only four issues.
(BTW, the story with the robot was published in Fat & Slat #3.)
While Flash and Buck were primarily newspaper comic strip characters, both had comic books that reprinted their newspaper appearances.
In addition, there were numerous space-hero characters created specifically for comics including SpaceHawk, Rex Dexter, and Rocket Kelly.
The main difference between "Comics" McCormick and it's rival series, SuperSnipe, is that "Comics" daydreams about interacting with comic characters, but SuperSnipe actually tries to do heroic deeds like capturing spies or rescuing kittens, but invariably screws up and ends up being grounded (or worse).
This story from Holyoke's Terrific Comics #6 (1944) is written and illustrated by Ed Wheelan, who did over 300 stories during his career from 1938-1949, almost all of them as both writer and artist.
