Ra's al Ghul's Decoy (Earth-6531)

"Gotham's time has come. Like Constantinople or Rome before it, the city has become a breeding ground for suffering and injustice. It is beyond saving and must be allowed to die. This is the most important function of the League of Shadows. It is one we've performed for centuries. Gotham...must be destroyed."

- - Ra's al Ghul to Bruce Wayne

Ra's al Ghul's Decoy was a man who pretended to be the real Ra's al Ghul at the Shadow Temple, in the Himalayas, while the real one disguised himself as Henri Ducard to train new members of the League of Shadows.

Training of Bruce Wayne
Following seven years of living abroad after leaving Gotham City, Bruce Wayne was arrested in China for theft of food. In a Bhutanese prison, he was met by Henri Ducard, who proposed for Bruce to join the League of Shadows, which he only described as an elite group, led by Ra's al Ghul at the Shadow Temple, in the Himalayas. Seeing only death if he remained locked, Bruce accepted.

Duel and Death
During his multiple tests, both physical, and mental, alongside Ducard, Bruce was watched by the decoy, who posed as Ra's al Ghul to evaluate him. At Wayne's final test, Bruce was tasked with killing a serial rapist and murderer with a sword, something which he could not bring himself to. This led to the decoy explaining the League of Shadows' goals to Bruce, stating they are the saviors of humanity.

When Bruce turned against them, the League attacked him, and a battle soon ensued when Wayne threw fire at the Shadow Temple, killing many. He dueled the decoy, which ended with his accidental death when debris fell on him, instantly killing him.
