Jack O'Dwyer was the Wayne Financial director and close friend of Bruce Wayne. He lost his life in the Battle of Metropolis when General Zod was unable to control his heat vision, causing the Wayne Financial building to crash down.
Jack was an employee of Wayne Enterprises in the years before the Black Zero Event, eventually becoming a director for Wayne Financial and gaining the trust and friendship of the company's CEO, Bruce Wayne.
Battle of Metropolis and death
In 2013, General Zod and his followers attempted to recreate Krypton using the Black Zero and a world engine. The Black Zero was positioned above Metropolis' center, with Wayne Financial blocks away. Jack and a number of employees were in the building when the Black Zero started its attempt to terraform the Earth. At the same time, Bruce Wayne arrived in Metropolis from Gotham City, having seen the potential damage it could cause. Taking a vehicle, he called Jack and instructed him to clear the building of its employees. Jack agreed and cleared the building, although he lost connection with Wayne. When Superman and Zod fought, Superman was flung into Wayne Financial, floors below Jack's offices. At that time, Bruce Wayne saw the heat vision from General Zod, which broke through the building with Jack in it. In his last words, Jack said a prayer and died as the building collapsed. Bruce Wayne watched in horror and attempted to find Jack, only to find nothing.
