Captain Ahab is the Captain seeking revenge on Moby Dick in the book Moby Dick.
Following the arrival of Proteus in Midtown Manhattan, spectral activity spiked. At a library, ghostly versions of Captain Ahab along with The Frankenstein Monster and Mr. Hyde manifested. They are captured by the Ghostbusters and later seen in the Containment Unit while Slimer performs reconnaissance.
