Bulk

Roger Stern and John Buscema introduced Bulk to Marvel readers in 1986's Marvel Age Annual #2, launching this Copper Age curiosity into a universe populated by some of the X-Men's finest — Cyclops, Iceman, Beast, and their alter egos share the pages where Bulk makes his mark. With appearances spanning a remarkable 25 years and a footprint across Power Pack, the Evolutionary War Omnibus, and Marvel Age Annual, this compact but enduring figure punches above their weight in collector significance, boasting two key-issue appearances despite a slim catalog presence. For fans who love hunting down the hidden corners of the Marvel Universe, Bulk is exactly the kind of discovery that makes digging through long boxes so rewarding.
