There is reference to a mother cutting the vocal cords of her child as a baby, a father beating two children as "training" who are often shown as young with black eyes and one with a broken arm
Four characters are shown to become Doctor Fate, which could be considered possession since Nabu takes over their bodies and refuses to release them at first. One character permanently becomes Doctor Fate.

In the most recent episode, Violet Harper is referred to by she/her and they immediately shut the person down. They also spent the third season until halfway through this one using she/her because they had not come out or realized that they are nonbinary
