It's interesting how his hair reverts, but he keeps the uniform. Like using it drained him enough to not be able to completely hold his transformation, but he hasn't gone full human either.
Really is, the rest time the only bit of him that went back to human colorization was his hair and eyes, but after that when ever he uses his wail, his whole body reverted back to human
When I was younger, I thought he unlocked even stronger form, because they even play music when he transforms I assumed it was gonna be something like Goku going super sain And when he switched back very quickly, I just assumed he hasn’t controlled it yet, so he couldn’t hold onto that form
I think it’s a sign of the timeline glitching. Cuz remember Future Danny went back to the past disguised as Danny. Past Danny is stranded in the future. Could also because Danny’s powers were draining.
I always thought of it as some variation of Dark Danny's Shapeshifting ability. With his hands bound like that and surrounded by future versions of his enemies there was only one move he could do
The Ghostly wail is one of Dannys Destruction Attack that requires atons of his Energy to use it but since danny haven't try to practice using the Ghostly Wail it will end up drain all of his Energy and turn him back to normal cause its his First Time using the attack
Danny phantom is not trans. I dont know what kind of stuff does the Phandom cook, but this certainly is not a good dish. Its a great idea, but it isn't canon!
