There are many fanfictions where Danny, as the Ghost King, is summoned by various cults, and thus he meets the Justice League or the BatFamily. However, you know what I've never seen? Danny's complete hysteria in this situation
What am I talking about? Usually, if a sacrifice is used in a ritual, they're still alive by the time Danny arrives, so the king can collect the offering himself. Or there might be no sacrifices at all. Or Danny might become super-cool and immune to sacrifices, and since he's the king of the dead, why would he be afraid of corpses? However, I strongly disagree with
Think about it! When Danny overthrew Pariah, he was only about 15 years old in the cartoon's timeline. Did he see people with abrasions? Yes, often. Burns? Constantly on the bodies of his friends who had been shot by the GIW or the Fentons. Any dirt? Maybe, but only ghosts, and ghosts, firstly, green, which makes the brain perceive this dirt differently, secondly, a ghost can flatten, and he immediately returns to his original form, although just now he was a puddle. Can a people do this? No.
And now, imagine, the news that the King has changed spreads among the cults. Some particularly dubious cult immediately decides to "establish connections" with the new King, and for this, of course, they need the most beautiful sacrifice they can offer. The League is too late, and a number of people have already been brutally slashed in the ritual, perhaps even having their heads impaled on stakes. Danny is called upon, and he is a teenager who has never seen anything like this before
And so the Justice League gets to meet an incredibly powerful teenager, the Ghost King, who is hysterical, maybe even trapped in a ritual circle with the bodies, and it only makes things worse. No one expected this reaction from the Ghost King, and the League is already starting the "victim" protocol in his direction, and all they want to do right now is get the boy out of the traumatic situation and figure out what the hell is going on.
