Newton had always told DC that the only series he would like to draw other than "Batman" and "Captain Marvel" was "All-Star Squadron". Editor/writer Roy Thomas tapped into that interest by proposing that Newton draw "Infinity, Inc.", featuring the children of the original All-Star characters. The first issue scheduled to contain Newton's art was "Infinity Inc." #11 featuring a five-page framing sequence by Newton which surrounded a story drawn by George Tuska and Mike Machlan. Newton was to begin penciling the entire book with issue #12, but the letters page in issue #11 told of Newton's death. Newton suffered a massive heart attack in his home, after dealing with months of a debilitating throat ailment. He died three days later on August 19, 1984, in a nearby Mesa hospital.
