Kai Leng was part of the N7 Program
It’s not hard to imagine that Cerberus deadliest Assassins were part of the N7 program. Kai Leng was a worthy adversary, and as such, his obsession with Shepard probably began around the time he started the program and heard of Shepard’s accomplishments. Despite being a great soldier, Kai Leng was dishonorably discharged and imprisoned for 20 years in an Alliance prison after charge of first-degree murder.
