In addition to the below, in the Japanese version, the boss of the first round is called Damnd. His name was changed to Thrasher for the American version. The boss of round 2 is called Sodom in the Japanese version. He was renamed Katana for the American version.

In both versions, you can hurt Damnd twice by refusing to bow down before him, and then telling him you don't know he rules the streets. However the Japanese version has Damnd ask an additional question: do you think he's weak? If you answer yes, he loses more health. This was removed from the American version.

In the Japanese version, Abigail will ask you a series of questions before you fight him. If you get the answer every question correctly, you'll be given an extra continue. The American version removes Abigail's quiz completely. However, this might have not originally been the plan -in the instruction manual, Abigail's bio states "you'll have to answer his questions", which is referencing the removed quiz segment.
