Donar

Debuting in Marvel Age Annual #3 in 1987 — courtesy of the creative team of Steve Englehart and Al Milgrom — Donar is a rare Copper Age Marvel curio whose small but collector-noted footprint spans an impressive stretch of publishing history through 2019. With appearances alongside titans like Captain America, Thor Odinson, Mr. Fantastic, and the Human Torch, this character has kept genuinely august company across Marvel's pages. Three catalog appearances may be a modest tally, but one of them carries key-issue status, making Donar a tantalizing discovery for the dedicated completist hunting overlooked gems in Marvel's deep catalogue.
