Iron Man 250 / September 26, 1989
My first Iron Man and first comic with Doctor Doom. Part of Acts of Vengence.
Doom and Iron Man are transported by Merlin to the year 2093 to assist King Arthur against Andros Stark.
Two things stick out to me. One Iron Man had to go to Radio Shack for replacement parts. Two Arthur's return was delayed because his future parents decided to put him in cyro until they were ready for a child.
