Someone throws a test tube of chemicals (Sulfur Acid), causing an explosion; another very large, loud explosion causes windows to break and many rooms to be consumed by fire (the flames nearly engulf a couple of people). The man puts the chemicals in a mixer that could cause massive explosion and sets a timer. He breaks the keyboard making the bomb unrefusable.
A person is bitten by an invisible animal trying to inject it with a serum (we hear him yell and see blood on his hand). An invisible gorilla escapes from the cage causing a chase. The man runs into another person who also joins in the chase. She tries banging in the door but charges at the two men. Before he attacks them, she is shot with a tranquilizer; also, a person tries to shoot another with a tranquilizer. The needle stuck on the animal floats downwards until she is knocked out.
A man schedules an animal to be vivisected after being visible again. This is not shown, only implied. A female scientist complains of the man dissecting the gorilla's brain. The man replies saying that the lab is not a zoo.
A person is pushed into a pipe, causing a large bloody gash on the person's face and neck; a few times we see the body lying on the ground (with an extremely bloody face and neck) and we eventually see the person choke a bit before dying.
A woman's shoulder gets cut by a rapidly-moving elevator when she tries to get out of its way while climbing through the ladder of the elevator shaft. She almost falls down but a chunk of her arm squirts out blood. The elevator comes down but stops before it slips on the two.
We see a red serum flow through an invisible animal's veins, then watch the veins, muscles, bones, organs and skin slowly become visible again (the animal makes loud noises and thrashes); at one point during the process, the animal starts having a heart attack and is shocked with defibrillators a few times and is then fine.
After a person injects a serum into an I.V. tube, the person starts convulsing violently, yelling, and eventually disappearing (during the process, we see the person's muscles, organs and bones). In another scene, we see a red serum flow through the person's veins, then see the person convulse while bones, organs and muscles reappear and then disappear.
A person is thrown face-first into a pole by a water visible man, causing a bloody facial cut; a person is punched, kicked in the face, and then knocked to the ground; a person punches another and knocks the person into a table; a person kicks another; two people are slapped; a person steps on another's neck; a person throws another around a bit and grabs the person's neck
A man uses a fire extinguisher to find a trace of the invisible man. The Invisible man is visible for a few times but he charges at him and punches the man in the face and kicks him in the head almost dead. A woman drags him inside before the door shuts closed.
A woman lifts up a man's shirt and the slashed crowbar wound on the man's stomach is seen briefly. The woman uses her hand and feels inside his stomach by pressing it into the gash and the man obviously screams in pain saying that the crowbar wound didn't cut any of his organs.
An invisible man with a crowbar tries to attack a man and a woman but the man knocks him down with the crowbar in his hand, the invisible man gets electrocuted transforming his water soaked body with burned muscles and we can literally see his skeleton as the result!
A man without skin with muscles and veins shown grabs a woman and she falls on the elevator roof. The man and the woman have a fight grabbing each other. The man does a bear hug to the woman wanting her to kiss him but the woman steps on the cord detaching the elevator and the man falls to his death
An invisible man goes to someone's apartment to spy on them. After seeing them having sex, he gets mad so he throws a rock at their window when trying to make love. In another scene, he scares two kids in a car by removing his shades exposing the two holes inside his eyes. The kids get terrified and screams.
One implied rape read this: Visiting the woman who lives across the way from his home, Sebastian (who's invisible) moves her mirror around like a ghost and then suddenly grabs the woman and throws her to her bed (but we don't know if he does anything else to her or not) but it was implied that she was raped.
A man is strangled by an Invisible Man and he is thrown off an overhead pipe and cuts his carotid artery on a metal outcropping. Blood sprays from his neck and he slowly bleeds to death. Blood spills out of his neck and leaves a big puddle on the floor with some blood smeared on his face. Very bloody and intense.
A person is impaled through the chest, causing a bloody and fatal wound; another person is stabbed in the abdomen with a pole, which is then pulled/scratched out of the bloody wound and the man groans in pain. An invisible man locks the door sealed and turns the temperature to -40 Degrees (another person feels around inside the bloody wound and then tapes it up).
A woman splashes blood on an invisible man to make him visible. She is grabbed and knocked down. The Invisible man flips the gun to face her and shoots her in the heart with a tranquilizer gun, then the person's neck is twisted with a loud snapping sound. The man covered in blood wipes the blood on her shirt and her face trying to make her smile. The survivors find a trail of blood leading to the freezer and finds her body all covered in stained blood.
A woman is strangled to death with a wire, mostly off-screen and we see a POV of it with the Heat cam. We later see in a Heat Cam of her thermal body. Her dead body falls out of a locker. There is a close-up of her bloodshot eyes.
An invisible man is repeatedly burned with a blowtorch running around out of the elevator on fire. His clothes and parts of his skin gets burned alive but still survives., struck over the head with a crowbar, and electrocuted. All this happens in a short span of time but near his death, we can still see his muscles and skeleton.
At his house, an old man is pushed into a pool by an invisible man, choked, and held underwater, lifted back up and then pushed downwards until he dies trying to scream for help of his wife. (We see the lifeless corpse floating in the pool afterwards).
An invisible gorilla picks up a rat. Holds it squeezing its body, and bites its head off. Very startling and bloody. and we could see the mouse's bones getting ripped apart and the invisible gorilla's teeth having blood dripping down.
An invisible man gets irritated of a barking dog and in a HEAT CAM he picks up a dog which the dog whimpers the man and smashes the dog against the interior wall of their crate (Smudges of blood is seen on the metal). The scene is shown through a thermal camera but is nonetheless very messy and disturbing.
A person pours several bags of blood on a floor (we see the bloody floor a few times); also, several people have bloody hands, faces and clothing, and we see several bloody corpses as well. A person with visible bones and muscles is seen a few times.
