Torres was friends with artist Al Williamson in the early 1950s and occasionally assisted him on work for EC Comics with fellow artists Frank Frazetta and Roy Krenkel (known as the Fleagle Gang). The story which was to be Torres' first solo EC story, "An Eye for an Eye" in Incredible Science Fiction #33 (Jan.-Feb. 1956), was rejected by the Comics Code and did not see print for the first time until 1971.
When the E.C. comics line failed after the enforcement of the Comics Code, Torres (and several other E.C. alumni) went to Atlas (later to be known as the Marvel Comics Group) and drew a number of short stories for their mystery titles in 1956-57.
From October, 1968 until March, 1980 he drew the satires of contemporary U.S. television shows as the penultimate feature in Mad magazine (whereas Mort Drucker drew the movie parodies in its opening portions).
He was named #61 in Atomic Comics' (retailer) list of The Top 100 Artists of American Comic Books.
