DP HC - Ghostly Attire
I hc that when Danny turns into Phantom, he can make it so he's still wearing the clothes his human form is wearing, but not only does he specifically have to concentrate on that begin the case as he transforms, but they will end up being black, white, & possibly green like his hazmat. Sometimes with his logo featured depending on the outfit.
The clothes have to match his costume's color scheme.
He just doesn't have much reason to use this ability of his normally.
Vlad can do the same thing, but like Danny, he has no real reason to do this.
Their costumes are actually merged with their ghostly aura & it gives them regenerative properties as well as a glow. If their clothes are removed, then the next time they turn ghost, the clothes will disappear & reappear on their body. Good as new.
When not in use, it's converted into energy & stored inside their core.
If they're holding something else & concentrate on moving their aura from the one they're wearing to this new one, then the ghostly properties of the old one will relocate to the new one & it will change colors to match their color scheme.
This will make this new outfit, the default one.
Only Vlad knows this.
If Danny were to ever learn how to do this & changed his look, he'd find that he's left looking at the same hazmat he died in in his hands. White with black accents.
