Phantoms in Fawcett
is a Danny Phantom and Shazam! crossover where Danny and Dani, on the run and hiding out in Fawcett, run into Billy and more or less adopt him, all while each party is unaware of the other's secrets.
- Dramatic Irony: Danny and Dani don't know about Billy's secret, and vice versa.
- Family of Choice: Danny and Dani quickly bond with Billy as a younger brother figure.
- If You Ever Do Anything to Hurt Her...: Danny tells Tawny that if he's lying or hurts Billy in any way, Danny will end him. Tawny seems to approve of his protectiveness.
- Mutual Masquerade: Danny and Dani don't initially know that Billy is Captain Marvel, and Billy doesn't know that his two new siblings are half-ghosts.
- One-Steve Limit: Billy lampshades the confusion that the siblings being named "Danny" and "Dani" would cause, and assumes from the looks on their faces when they introduce each other that that's the goal.
