In Pierrot's opening killing spree, much of the blood has been edited out.
Also, originally one of the body guard's bullet-riddled body slams into the
car; that part of the scene was removed.
When Pierrot first breaks free from the testing facility, the original is
far more gory than what CN showed, including a lot more blood on the bodies,
walls and on Pierrot himself. Also, the bones sticking out of one of the lab
technicians (yech!) have been erased.
In the scene where Spike gets shot in the shoulder (at the end), originally
a spurt of blood came out from the wound. It has also been erased.
If you notice any edits that I missed, I would appreciate
it if you e-mail me.
