Fan Casting Enter the Knight

When he turned 18, Bruce Wayne left Gotham to make himself into a weapon to protect Gotham City and honor his parents legacy. He travels the world for years and is trained by many of the best fighters, detectives, and inventors in the world. During his training he meets another man, on the same mission he is, his name in Minhkhoa Khan. They travel the world together, training together, fighting together, and they become brothers. The final man they seek out to train them is the legendary Ra’s Al Ghūl, the leader of the League of Assassins. When their training is complete, Ra’s gives the two of them a final test, they each must kill a traitor to the league in cold blood. Bruce immediately refuses and watches in horror as Khoa kills him instantly, and kills the man given to Bruce. Ra’s is disappointed as he had seen a Bruce as the only man who could succeed him, but was unwilling to do what was necessary, but Khoa lacked the motivation to succeed and so he sentences them both to die. The brothers flea the league, only to fight each other over their conflicting morals. It is revealed that Khoa set out on his mission because he views crime fighting as an art, and enjoys bloodshed. This leads to them parting ways, and for Bruce to bat him from ever going to Gotham.
