Angel Eyes

The Bad
Description: A ruthless, unfeeling and sociopathic mercenary named "Angel Eyes" (Sentenza - Sentence - in the original script and the Italian version), who always finishes a job he's paid for (which is usually finding...and killing people). When Blondie and Tuco are captured while posing as Confederate soldiers, Angel Eyes is the Union sergeant who interrogates and tortures Tuco, eventually learning the name of the cemetery where the gold is buried, but not the name on the tombstone. Angel Eyes forms a fleeting partnership with Blondie, but Tuco and Blondie turn on Angel Eyes when they get their chance.

Angel eyes (played by Lee Van Cleef) was the main villain in The Good, the Bad and the Ugly. He was a dangerous bounty hunter who dueled against Blondie and Tuco to find the gold hiding in sad hill cemetery, on his journey he faced the duo many times without success, he first met them in a prisoner of war camp where he badly injured Tuco to get information on where the treasure was, he later faced them in a small town but before having the chance to kill them they fled. Upon finally arriving at the cemetery he battled them once more in a gun draw and died at the hands of the man with no name, who shot him right into an open grave.
