The Purple Slime (also known as Purple Ectoplasm) is a unique form of Ectoplasm observed during the Tiamat incident.


After the Ghostbusters seemingly destroyed Tiamat by Crossed the Streams on her, they were covered in Purple Slime, presumably her innards.


Purple Ectoplasm is also a rarer variety. The working theory is the Purple Ectoplasm is a more potent strain of Psychomagnotheric Ectoplasm. [1]

Our working theory is that it was a more potent strain of psychomagnetheric ectoplasm."
