Ghostbusters: Sanctum of Slime
In the modern era, Ismael is the sole remaining member of the Cult of Dumazu. Acting as his vessel, Ismael can commune with Dumazu. At some point, Ismael was admitted to Parkview Psychiatric Hospital and declared clinically insane. He was observed to be prone to bizarre delusions and terrifying hallucinations. During the New Year's 1989 holiday, Ismael received a message from Dumazu, that he was coming at long last. Just then, Ismael also received a new room mate named Janosz Poha.
Playing on Janosz' openness to the supernatural, Ismael convinced him to help steal a shard of the Relic of Nilhe. In exchange, Dumazu would award Janosz Dana Barrett. Years later, Janosz is released and takes a job at the American Museum of Natural History where a shard was on display. Janosz stole the shard and gave it to Ismael. Ismael then went back on the deal and took over Parkview and its occupants. In order to complete the Relic of Nilhe, Ismael posed as a psychiatrist when the Ghostbusters arrived. As Dr. Michael Tesmon, an anagram of his full name, he provided a cover story and gave the junior team his shard. Ismael then waited as they assembled the Relic and defeated the paranormal opposition.
When the team returned to Parkview in search of Dr. Tesmon, Ismael appeared and took the Relic. He chanted a spell which allowed Dumazu to possess him . Ismael and the junior team were pulled into another dimension through a painting. After making short work of Ismael, the team then faces Dumazu, himself.
A few years after the Vigo incident, Ismael is a patient at Parkview and began painting a portrait of Dumazu's Nether-dimension.
As the junior team fights Ismael in the final level, he switches the frequency of his energy aura between red, yellow, and blue. When his aura is red, use the Proton Beam. When his aura is yellow, use the Fermion Shock. When his aura is blue, use the Plasma Inductor.
- His name comes from a Biblical figure in the Judeo-Christian traditions.
