When Spider-Man goes to Kingpin’s building to talk or fight about Black Cat’s remaining debt, he is attacked by The Spot, who wants to test his new powers of traversing the spotted dimension. Spider-Man can’t get the edge on him, but The Spot isn’t strong enough to really hurt Spidey. Also, the symbiote is diligently trying to find Spider-Man.
