What Could Have Been: Team Ninja originally asked Bungie for permission to use the Master Chief, which proved impossible due to storyline restrictions. But the staff at Bungie were intrigued with the idea and wanted to try something similar. As a result, Bungie developed the concept of a Spartan not entirely connected to the Halo storyline who could conveniently and somewhat plausibly be fit into the Dead or Alive universe. This concept evolved into the character of Nicole.
