Project Metallo

Project Metallo was a technological program created by Lex Luthor to create cybernetic humanoids for military use and as a peacekeeping force.

History
Lex Luthor was using this program to create a cybernetic peacekeeping force in an attempt to assist police offers and military alike.

John Corben was enlisted in the project after being caught in an incident that left him paralyzed for the rest of his life. However, Luthor recruited him with this project, letting him know this was the only way he could be live again. John inevitably became corrupted with the program and murdered innocents, along with multiple attempts at attacking Lex.

Lex eventually shut the project down after the Daily Planet released an article containing footage of Corben losing his mind.
