During the film's opening monolog that provides some background for the main story, one of the Jenova aliens in seen floating in a tank of fluid. It's breasts and nipples are visible. This is very brief and easily missed.

Absolutely nothing.....

Cloud now bleeds blood during the final fight.

Over an entire half of this film consists of chaotic, fast-paced fight scenes involving swords, firearms, fists, and explosions However, the battles are heavily stylized and completely unrealistic. Do note that the graphic nature of the violence differs between the Original release and the Extended Blu-ray Edition.

Original Version:

The violence is quite intense and very chaotic, but it completely lacks blood or gore. Characters often battle each other with swords, firearms, fists etc. but it is heavily stylized and unrealistic.

Early on in the film, Cloud Strife has his goggles shot off with a gun. A small amount of blood is visible for a few moments.

Extended "Complete" Version:

The violence is mostly the same in this version, save for a few new scenes.

There is a flashback depicting the character Zack's death. He is briefly shown lying in a puddle of blood and water as he says his last dying words to Cloud.

5 uses of damn,4 uses of hell, 1 use of son-of-a-bitch, 1 use of ass.

None.

Due to the stylization of the battles and lack of realism, most audiences should be able to handle it.

Due to the extremely fast-paced stylization, the battle sequences may be nauseating.
