Today's Fact
Checked against independent sources — the issues are cited below.
Avengers Vol. 1 #93 (1971) opens with the Vision staggering into Avengers Mansion and collapsing inert on the floor, his synthezoid systems failing beyond anything a workbench could reach. Hank Pym, arriving in his Ant-Man identity, volunteers for the only repair route available: shrink down and go in after the fault personally.
Inside the Vision, Pym finds a landscape closer to a Dalí painting than a circuit board, and the synthezoid’s defences treat the tiny intruder accordingly. He has to battle through automated antibodies and surreal internal machinery while talking himself steady — a surgeon being attacked by his own patient’s immune system in real time.
Pym reaches the failure, restarts the Vision’s systems from within, and escapes before returning to full size outside. The revived Vision then delivers the issue’s second payload, the long flashback explaining the Kree-Skrull War crisis — meaning the Avengers’ most important intelligence briefing only happened because Ant-Man performed surgery from inside the messenger.
Why It's Obscure
Every other Avenger waited in the hallway; the smallest one scrubbed in and entered the patient.
