Doctor Stack

Doctor Stack made their Marvel debut in The New Mutants Annual #4 in 1988, arriving at the height of the Copper Age when annuals were event comics in their own right. With a catalog trail stretching across 23 years, this is a character whose presence echoes through some genuinely significant corners of the Marvel Universe — sharing pages with heavy hitters like the High Evolutionary, the White Queen, and Logan across titles including The West Coast Avengers Annual and the Evolutionary War Omnibus. The company Doctor Stack keeps speaks to a character woven into Marvel's larger tapestry, even if the appearances are rare and all the more collectible for it — a quiet footnote that dedicated completists and Copper Age enthusiasts will want to track down.
