Dr. Keith Kincaid

A Silver Age creation of the legendary Stan Lee and Jack Kirby, Dr. Keith Kincaid made his debut in Thor #136 back in 1967 and has been woven into the fabric of the Marvel Universe ever since — a quietly enduring presence across more than five decades of storytelling. His journey through the catalog has kept him in remarkably distinguished company, sharing pages with Thor, Sif, Steve Rogers, and Captain America across titles like Thor, Captain America, and Quasar. With team affiliations spanning both the Avengers and the Serpent Society, Kincaid occupies a fascinatingly unlikely corner of the Marvel tapestry — a figure who bridges worlds that rarely overlap. Collectors with an eye for deep-cut Silver Age characters who carry genuine Kirby-and-Lee DNA will find him a rewarding discovery.
