Spectacular Spider-Man #89 Apr 1984
"Power-Search!"
After struggling in her recent battles against super-powered foes,
Felicia decides that she needs additional powers to complement her natural abilities.
The Black Cat first visits the Baxter Building, then Avengers Mansion, and finally ends up at the former lab of Dr. Harlan Stillwell.
Has anything good ever come out of Dr. Stillwell's laboratory?
The Black Cat doesn't care; she wants more power!
Meanwhile, the wall-crawler is drawn towards a mammoth citadel in Central Park...
and suddenly disappears!
