Get That Out Of Your Mouth (You don’t know where it’s been!)
is a Danny Phantom and The DCU crossover AU, in which Danny is transported to the DC universe... and apparently tries to eat some Kryptonite.
- Accidental Kidnapping: Danny is assumed to be part of the trip the alternate Mr. Lancer is supervising, and when he can't convince them otherwise he just goes with it to get a ride to civilization.
- Alternate Self: Soon after ending up in the DC universe, Danny encounters the local version of Mr. Lancer.
- Trapped in Another World: Danny falls through a portal into the DC universe, which closes before he can return.
