Mimir

Rooted in Norse myth and brought to Marvel's Bronze Age cosmos in 1975 by Roy Thomas, Bill Mantlo, and Sal Buscema, Mimir is one of those rare figures who carries the weight of ancient legend into the vivid four-color world of Asgard. Debuting in Thor #240, this enigmatic presence keeps extraordinarily august company — sharing pages with Thor, Odin, Loki, and Balder across Thor, Thor Annual, and Thor: Tales of Asgard over a span of nearly four decades. Appearances may be scarce, but in the mythic tapestry of Marvel's Asgardian saga, even a handful of moments alongside gods of that magnitude speaks volumes.
