The blue-skinned species, known as the Na'vi, have humanoid like bodies. This tribe doesn't wear traditional clothing. Because of this, you can see the areola and nipples on male and female characters in some shots.

A (human) woman wears a white tank top throughout several scenes, and some cleavage is seen in several shots in two separate scenes.

A brief suggestive between Jake and Neytiri shows the two kissing and beginning to passionately caress each other. There is no nudity, but they wake together the next morning, and Neytiri explains they are "mated for life." In the extended edition, this scene includes the two touching their queues together, implying they can "feel" each other (as explained earlier in the film).

A few sexual jokes and lines are tossed about, including a masturbation quip from Dr. Augustine ("don't play with that, you'll go blind" when she sees Jake playing with his queue).

The battle at the end is fairly violent and many creatures/humans die; some deaths are presented in shocking detail.

There's a large battle between humans and humanoid aliens: Several helicopter gunships and two larger flying vehicles attack the aliens with bullets and missiles, the aliens attack with arrows while perched on flying dragon-like creatures, and we see several helicopters blow up and many aliens are struck and crash to the ground.

An unfortunate humans' head and shoulders end up in a banshees mouth.

Explosions consume man, alien and beast alike.

On fire, a horse-like creature runs for its life.

Neytiri kills a human with two well-placed shots.

A soldier in huge mechanized armor fights with an alien riding a large tiger-like animal: The animal is eventually stabbed repeatedly by the soldier and falls dead on top of the alien, who tries hard to free herself.

A soldier in huge mechanized armor uses a spear to fight with an alien holding a dagger: after several blows, the alien throws the dagger, the soldier grabs the alien by the hair and is ready to kill him with the dagger but another alien shoots two arrows into the soldier's torso killing him.

Several soldiers on foot and a few soldiers in huge mechanized armor attack aliens who charge while riding alien horse-like animals; we see many aliens shot and killed (little blood is evident) and a few humans are killed by arrows. Soldiers on foot and in huge mechanized armor are attacked and crushed by rhino-like animals that charge them (the soldiers shoot back) and then are attacked by panther-like animals that have big teeth.

Gunship helicopters attack aliens with gas and explosives, and shoot at a gigantic tree with missiles: the aliens attack with arrows that have no effect and when the tree collapses aliens scramble to get away and many are presumably crushed and killed.

An alien jumps onto a flying gunship, shoots a couple of soldiers with arrows, strikes several others with a spear and is eventually shot dead and falls off. A flying dragon-like creature with an alien rider grabs a soldier out of a helicopter with its mouth and flings him out.

An alien is surrounded by alien panther-like animals at night, he tries to scare them off with a flaming torch, they attack, and he defends himself by hitting them with the torch and by stabbing and slicing at them with a knife; an alien shows up and shoots several with arrows, and she uses a knife to finish off an injured animal.

A soldier shoots at a departing helicopter, first with an automatic weapon and then with a pistol; we see several bullet holes on the helicopter's windshield and find out that one passenger has been shot -- she lifts her hand to show blood on her abdomen.

An alien has a wooden spike sticking out of his chest and he dies (no blood is seen).

An alien attacks another alien with a knife, slices him on the arm, and the second alien suddenly falls down unconscious; the first alien prepares to cut his throat when a female alien jumps on him, throws him down and snarls at him (we see his nose bleeding).

Two aliens fly perched on dragon-like creatures, when they are attacked by a much larger dragon-like creature, with big teeth; they fly through jungle and manage to hide behind trees.

Two sleeping aliens are almost crushed by a huge tank-like machine that knocks trees down along its path: one alien wakes up and tries to drag the other one away, who remains unconscious while trees are crashing all around them -- eventually he wakes up, climbs on the machine, breaks its cameras, and jumps to safety when he's fired upon.

A man is suffocating while trying to reach an oxygen mask; he passes out but an alien puts the mask on his face and he starts breathing again.

Two aliens are tied up, another alien approaches with a knife, and she cuts their bonds. An alien is tripped by a rope that's wrapped around his ankles and he's surrounded by several aliens with arrows aimed at him.

A large rhino-like animal confronts an alien, who wonders about shooting it with an automatic weapon but is told that the animal's hide is too tough: the animal leaves when a larger, tiger-like animal with sharp teeth and claws shows up and starts chasing the alien, who shoots at it but the animal grabs his gun away, then grabs him and flings him in the air, and he runs and falls off a cliff and into water.

We see a dead man in a coffin and during a cremation, we see a box containing the body of a dead man, placed in an incinerator, the flames erupt and the box is engulfed.

Contains moderate intense violence.

PG-13 violence type: blood and brutal.

Aerial clashes involve banshees vs. the humans aircraft. And while the Navi get mowed down by missiles and gunfire, many of their arrows somehow penetrate cockpits, taking out pilots and gunners, by shots to the face and chest, shown onscreen.

Neytiri takes out a viperwolf with an arrow.

Shit, ass, damn, crap, bitch, dick, bastard, and balls.

Alcohol and tobacco use.

2 minutes in, Jake watches a body burn in a cardboard box.

The final battle in the film between the humans and Na'vi is intense and emotional, considering that we see scores of soldiers (on both sides) get stabbed, shot, impaled and crushed by gunfire, arrow piercings and falling objects.

Jake has several close encounters with native creatures, which may be intense and in several scenes, they chase him in an attempt to kill and eat him.

Several positive characters are killed or mortally wounded on-screen during the movie, which may be disturbing for the audience.
