As mankind was created in the image of its creator, mankind created a species akin to its own.
In Ridley Scott’s Blade Runner, a bioengineered species known as replicants have been created by humans through the mind of Dr. Eldon Tyrell of the Tyrell Corporation.
Replicants are physically superior to their creators, though the models created by the Tyrell Corporation are only given a four-year life span. Despite this, they are subjected to slavery and punishment due to their involvement in a deadly mutiny, banning replicants from Earth. Therefore, police officers known as blade runners are given the duty to “retire” these replicants, terminating their existence.
