Artur Zarrko

Few villains can claim they stepped straight out of the future to bedevil Marvel's mightiest from the very dawn of the Silver Age, but Artur Zarrko — the Tomorrow Man — has been doing exactly that since Stan Lee and Don Heck introduced him in Journey into Mystery #86 in 1962. A time-displaced schemer whose ambitions have repeatedly put him on a collision course with Thor, Odin, and Balder across nearly six decades of Marvel storytelling, Zarrko is one of those deliciously persistent antagonists who refuses to stay in whatever era he belongs to. With 26 catalog appearances stretching from 1962 all the way to 2021 — including two key issues that collectors prize — he's a testament to the staying power of a well-crafted Silver Age concept. If you love the cosmic, time-bending corners of the Thor mythos, Zarrko is absolutely worth tracking down.
