Just, look at Digimon Adventure 1.
You have
Deaths of digimon, including sympathetic, friendly, and good Digimon.
The children dealing with the existential dread and uncertainty of not being able to return home, in a world that can very easily kill them.
The children's own social dynamic becoming strained, as people are pushed into roles they don't want, but have to fill to survive.
Tai's entire PTSD arc in the episode where he gets to go home for a bit. Nothing seems right anymore, his own home feels foreign, and he can't look at the world as simply as he could have before, leading to his ultimate decision to return. Not just to save everyone else, but because he can't stand the world he used to know.
Adults and parents making bad decisions, for justifiable reasons, that the children must disobey. As much of a coming of age moment as can exist.
Villains with sympathetic motives, and villains with unsympathetic motives, and how to handle the difference.
And then Adventure 02 immediately follows that up, with the single fact that some people have moved on. Joe and Mimi just aren't around anymore.
