Technically? One minor character is able to entirely remove his arms (they sort of just float and he can still control them when they are separated from him)
No characters are gaslit, but in keeping with the first movie the character 'Amanda Waller' is extremely manipulative and immoral. She directly manipulates a character into obeying by threatening to have his daughter placed in prison, vagueing that she can orchestrate her death.
a character’s relative suffers from a heroin addiction, and in flashbacks (seen on the window of the bus) they can be seen injecting the drugs into their arm.
approximately 50 seconds into the film (when a character is bouncing a ball around his cell) a bird is killed and it’s quite graphic. further on in the film, a cage of birds is doused in fuel and then set on fire - you don’t see them burn, but you hear the screams and it’s quite distressing.
In the first two minutes a bird is killed, and around an hour in a lot of birds get blown up. Both are incredibly graphic, and the second features lots of auditory screams that could be distressing.
A man has an aviary full of parrots, all of which die offscreen (but their screeching can be heard) when a villain sets the aviary ablaze. Harley Quinn mentions that her ex-boyfriend killed her dog, but doesn't give any details about the dog or its death. A tank full of cute but bloodthirsty alien cuttlefish-like creatures bursts and all of the aliens appear to die. Sebastian the rat survives and is not harmed at any point in the movie.
In the third act of the movie when all of the heroes are seeing Project Starfish for the first time, Starro (speaking through it's human hosts) tells the Squad that it has been tortured, taken advantage of, and uses the phrase about its captor, "he had his way with me." Grievous makes a face that, in my opinion, confirmed that he most likely raped or sexually assaulted the human hosts, and therefore Starro. It's only implied, but I believe it to be triggering in the way it's phrased and commented on by the characters.
multiple nameless goons have their throats slashed by sharp weapons, particularly in an extended action scene with harley quinn. one of them is particularly graphic, as his neck is slashed almost the whole way through, and blood gushes out of the wound and his mouth before he dies.
in the opening fight scene a character burns to death, and there are close up shots of their corpse. later on, several characters are set on fire but that’s less graphic and less drawn out
Alien starfish creatures attach to peoples' faces. Graphic damage is shown if the aliens are removed. A mad scientist character has several implants in his skin/head. The same mad scientist experiments on humans and the alien starfish. A minor character can detach his limbs, though feel pain in the limbs when they are shot.
A lot!
SPOILERS - mostly happens in the first 15 minutes or so on the beach.
To start the fight on the beach Pete Davidson/Blackguard is shot in the head and his face explodes. This happens very suddenly. There is a shot of the corpse later.
A soldier on the beach has their head sliced in half by a boomerang.
Michael Rooker/Savant's head is detonated by a bomb.
Later, a Starro victim is shown in the lab without the star and their face has been melted away.
In the second half of the movie, when the characters step into the experimentation part of the tower, someone being experimented on is seen convulsing due to the link to the creature being tampered with. This shot is repeated two or three times.
There are many scenes of characters falling off buildings or through holes/pits. They do not die but for a moment, the audience believes they might be dead
there’s a quick shot where a character throws a weapon that lands in someone’s eye, and [SPOILER ALERT] the antagonist of the film has a giant eye that gets speared by an object and destroyed in a somewhat graphic manner
Several.
Spoiler warning,
Mongal, several of Starro's extensions, Starro himself, and while Weasel is thought to have drowned at the beginning, a post credit scene shows him regaining consciousness and waddling off into the woods.
An entire family (with children might I add) is murdered in a violent revolution but I’m not sure of it counts since theres no survivors. However while redundant I should mention there’s also multiple characters with dead parents
Harley Quinn in other media is depicted very clownlike, but in this she only has powdered pale skin and colored hair. Look up images of her character to see if it would be a problem for you but in most cases it would not be
Polka Dott man (whatever he is called I can’t remember exactly) gets up in the middle of the night and walks off to vomit behind a bush. It’s barely visible and doesn’t look like vomit anyway, I wasn’t even sure he was being sick at first. Just watch out for the scene where he wakes up in the night and has the spots on his face if you’re worried about it.
syringes are used to inject devices into character’s skulls, a character suffers from a drug addiction and is seen with a syringe in their arm, there is a javelin used as a weapon
[SPOILER ALERT] In the second post credits scene Peacemaker is shown to be lying on a hospital bed in a state of comatose as a nurse tells a couple of Waller's agents that he will recover soon
There are no specific anxiety attacks but there are multiple scenes where characters experience extreme panic, including yelling, hyperventilation and thrashing.
In a sense, it's the entire plot of the film. They're on a suicide mission. Many die. One character even mentions wanting to die before going on the mission.
Opening scene includes a camera manipulation where the entire image spins and gives a vertigo effect. I watched it in imax and it made me a little nauseous
There is a brief mention that the main villain's hub was once used for Nazi experimentation and that the Nazis were protected there after WW2 before being killed eventually when the price to kill them became higher than the price to keep them alive.
In the bar scene when it focuses on Polka Dot Man dancing, it shows his point of view where he’s imagining all the girls dancing around him as his mother.
Main character is covered with polka dots, which is not a real illness, but the struggles he faces are similar to the experience of actual chronic illness
This is an *extremely* gory movie, there are many, many graphic on-screen deaths, including bodies exploding, being ripped apart, cut in pieces, eaten by King Shark, shot to death, etc, and the camera often focuses on corpses in various awful states of death
