The main question I asked was about how the robot could work for the Big Daddies to accept them, not about this Big Daddy. Like I said about Jack McClendon, the robots were considered useless in trial tests, which was why they were shelved in his workshop. Big Daddies are already less than human, and further mental chemistry would make these already aggressive protectors too irrational to anyone, especially if they can't tell the difference from a machine and a human. I agree with Willbachbakal about the pheromones. It's one of the only qualities of the Little Sister that helped the Big Daddies in bonding with them, much like how the same works for the other way around. It would make more sense if it was some type of Little Sister pheromone in the robot, than just jacking up the Big Daddies even more just to accept a robot surrogate. That's the thing about creating a character in fan fiction, is that you need to pay close attention to your source material, because if you don't know your source well enough, you'll end up having people think your stuff is this:
