The Electrocuted Ghost, also known as "Sparky", is the second ghost Erin, Abby and Holtzmann spotted. He is portrayed by Dave Allen. Shortly after Rowan North (Neil Casey) gave his train ticket to Patty Tolan, he disappeared onto the tracks, causing Patty to go tell him to get out. Instead of finding him, she finds a device on the tracks. The device then opens, revealing the Electrocuted Ghost, causing Patty to flee. Later, the team arrive with Patty and after inspecting the tracks for a bit, Sparky appears. The team decides to test their new proton lasers on him, but the beams do not have enough power to even reach the ghost. A train later hits Sparky, nearly killing the group as well. Patty then states he will be the third scariest thing on the train.
The Ghostbusters encounter Sparky again, alongside Gertrude Aldridge and Mayhem. They defeat all three.
