This "Over 60" employee of Tony Stark was intially thought to be a liablility when he spotted a Ghost at his workplace. When his suspicions proved true, Stark ensured Abe that there was a place for him at Stark Enterprises. Stark came to recognize Zimmer as a trustworthy and valuable employee. Zimmer helped Stark continue to function after a bio-chip implanted by Erica Sondheim was controlled by the Marrs Corporation and eventually became a deadly detriment. Abe also froze Stark's body into a cyrogenic state when he appeared to be dead.
