Leonard Steeple was the Vice President of REPCONN Aerospace and was replaced by Carl Rook.
He and Julia Masters fought to stop Poseidon Energy from buying out the company, and when RobCo Industries put an offer in later, he messaged Julia and asked her to help him fight once more and Julia agreed. However, Julia then used this to take a vote of no confidence on Steeple. He was replaced by Carl Rook and REPCONN was sold to RobCo Industries.
Leonard Steeple is mentioned only in Fallout: New Vegas.
