Spider-Man S01E15 - The Spider and the Fly/The Slippery Doctor Von Schlick

Spidey chases the culprit in an attempted theft of jewels from a countess and is surprised to find that his opponent, dressed in a black "Human Fly" costume, also has the ability to scale walls and can cross thin wires between buildings. 

Oil is being stolen in huge quantities by Dr. Von Schlick, a chemist villain garbed in a rubber, non-stick suit and armed with petroleum-based bubbles that he fires from his fingers to envelope Spidey.
