Iron Golem

The Iron Golem appeared in the 2011 movie called Metal Shifter. It was originally an artwork that was made by Earl, but due to an unknown substance that came from outerspace it was brought to life.

Apparently its a bacteria lifeform that can possess metal, in addition its highly toxic to organic material, with a single touch being fatal. The bacteria affecting the vessel it inhabits is capable of reconstituting itself.

Like most bacterial substances it is susceptible to alcohol.
