Two young brothers are raised as alchemists, but when they are severely injured trying to perform a forbidden act, they begin searching for the one thing that can save them; the fabled philosopher's stone.
This anime contains 69 potentially triggering events.
Not sure if this counts, but throughout the show, a homunculus character deals with extreme feelings of being detached from their surroundings, and often wonders who they actually are (and never come to a conclusive answer.) The homunculi are also repeatedly stripped of their human identities by Dante.
Ed and Al's father leaves without saying goodbye when they are still young. There is also an episode where two children believe their mother ran away from danger without them, but it is revealed to not be the case.
Riza shoots at her dog when he pees in her floor (it is comedic, I guess, the whole "bullet outline all around you" gag). The dog is not injured.
Alexander the dog and Nina the girl are magically combined into a painfully suffering chimera creature who begs to be killed (and is).
one of the main antagonist's power is that he is able to eat everything, including humans. the camera cuts away during these moments, but there is some audio suggesting what is happening.
In just about the most traumatic yet not explicitly gory way you can imagine :) well the death itself is a bit gory but no more than anything else in this thing... what happens before is the awful part. I bawled and yelled at my bf for showing me this when I explicitly asked for a lighthearted anime for once.
early on in the series, edward and alphonse try to make a toy for their friend winry. while it is not destroyed, the creation of it is shown, and it is distorted and creepy, making her cry.
(spoilers) No, but a character is a hollow suit of armor, and he is controlled from the inside at one point by a character with flexible/extendible limbs.
Lust says I wanted to die and Alphonse also has a few moments where he says stuff like "I should have died" or "there's no reason for me to continue living"
Nothing actually happens, but there is an episode where a fully grown adult woman who Al says reminds him of their mom sexualizes the hell out of Ed and really, really flirts with him, while COMMENTING on him being NOT an adult
One of the side character kinda became ill more than 10 years ago. And the main character is depicted having chronic pain (even if it shows only sometimes)
