"The Golem of Old Gotham" - Beware the Batmen (2013)

The name given to Rex Mason by the residents of Old Gotham saved by his actions, the Golem of Old Gotham was the protector of the rundown part of the city, fighting those hired by his ex-fiancée Sapphire Stagg to intimidate business owners and acquire their land for commercial property development.

He made his base in the rafters of an abandoned church, playing up to the myth of the namesake Golem, believing it was better to live there than in the sewers where he had originally been forced to hide.

“The Golem” had been active for five days and stopped every attempt made by Stagg’s employees on their criminal acts being carried out against retail owners.

Due to his role as a vigilante, he became the target of Harvey Dent and the S.C.U, leading to members trying to hunt him down. This led to his confrontation with Batman and Katana, who although managed to get away the first time, was revealed to be Mason in the church.

After successfully repelling highly armed criminals and the S.C.U, Rex chose to take up the name Metamorpho, which had been suggested to him by Katana – taking away the painful memories of “Project: Metemorpho” that gave him his powers and using them to benefit Gotham.
