Greko

DaiMon Greko, son of Garjak, was an odd Ferengi. He was boisterous, aggressive, and blunt. He left his homeworld to work on a Ridorian merchant ship. Somewhere along the way, he saved his captain's life when they ran afoul of a Klingon bird-of-prey. The captain rewarded young Greko. Greko invested this money in buying warp drive from the Breen and bringing it home to Ferenginar. There is now a statue of Greko in every Ferengi home.
