Mayor Lenny  (also known as Mayor , and The Mayor of NY ) was the Mayor of New York City who bailed the Ghostbusters out of jail to let them do their job and wipe out Gozer. After New Years Day 1990 and prior to the Thanksgiving holiday weekend in 1991, Lenny was succeeded as Mayor of New York City by Jock Mulligan.
In 1984, the Mayor bailed the Ghostbusters out of their jail cell, in which they were placed after the explosion at the Firehouse. Despite Walter Peck's accusations, he listened to Peter Venkman's argument that, if they could stop the impending threat, he would secure a re-election for himself. He gave them a military motorcade to get to Dana Barrett's apartment and had Walter Peck removed from his office.
Between 1984 and 1989, Lenny hired Jack Hardemeyer as his assistant. Jack jealously, yet needlessly, defended Lenny from the Ghosbusters, citing their association being harmful to the Mayor's run for Governor the following year. When the Ghostbusters were brought to Gracie Mansion, Lenny heard their latest claim but refused to help them. He returned to a party and was unaware Jack had the Ghostbusters committed to Parkview Psychiatric Hospital. As New Years approached, supernatural activity increased to unprecedented levels. Lenny spent an hour in his room talking to the ghost of former mayor Fiorello La Guardia. 
The next night, Lenny learned how Jack abused his power and had him dismissed by force. Just as the Ghostbusters exited the Manhattan Museum of Art with Dana Barrett and Oscar, Mayor Lenny arrived on scene. Weeks later, he awarded the Ghostbusters with a Key to the City during a ceremony on Liberty Island.
Mayor Lenny was a reasonable politician who wanted to stop the crisis in New York at any costs. He listened to his advisers patiently for advice before calling the Ghostbusters. He was also a Catholic, and valued the advice of the Archbishop, whom he called "Mike."
- Called "Lenny" by the Archbishop, his first name is presumably Leonard.
- The Mayor was made to look like mayor of New York City at the time, Ed Koch. 
- Lenny is described as a "likeable Democrat and a man of the people - particularly the Irish, Italian and Jewish people."  
- In Ghostbusters: The Supernatural Spectacular:
- The Mayor is referred to Hizzoner, New York slang for the Mayor. 
- The Mayor recalls how he has impeccable visibility with the Carson show, the Letterman show, Donahue, Griffin, and Good Morning, America. He's also published a book, done cameos on Kate and Ali and Ryan's Hope, and there was a play about his life in development. 
- The Mayor immediately dislikes Walter Peck who reminds him of his high school biology teacher. 
- The Mayor's first name was Ed and he was a ward captain. 
- After hearing Peter out, the Mayor muses to himself that Peter could be a dangerous opponent if he ever went into politics. 
- In the Ghostbusters II August 5, 1988 draft, Lenny was no longer the mayor. The mayor is a man named Maury. 
- The scene where Mayor Lenny mentions he had a discussion with the ghost of Fiorella La Guardia was a replacement scene done 4 weeks before Ghostbusters II's release because ILM could not do a ghost FX shot. 
- The surname "Clotch" originates from the Ed Naha written novelization of Ghostbusters II. 
- In Ghost Busted (manga), on chapter two, page 48, Jack refers to Mayor Lenny.
- On page six of Ghostbusters Issue #4, Lenny is listed on Peck's speed dial.
- Lenny appears on the back cover of Ghostbusters Volume 2 in a rendition of the scene he debuted in during the first movie.
