An au idea I will probably never have the time to expand on and write myself,
take it and be free my silly gooses.
Write to your hearts content (tag me so I can read them! Kaspertheanxiousghost on ao3)
Basically, Jack Frost but Danny phantom him.
Jack doesn't actually die in the lake, but the moon marks him as the winter spirit when his time comes, she acknowledged his actions and chooses him but because he was saved he didn't fully die.
Because of this she is blocked from guiding him in anyway. But he has a limited amount of access to the power he will gain once his death fully takes, when he uses the powers (maybe just the frost/ice while 'human') his eyes take on the icy blue of his spirit form.
He has an attachment to the staff but doesn't fully understand why it is important to him just that it is (maybe he brushes it off as being useful in his daily life)
The moon is hopefull that he can use this time to learn his core on his own since she can't guide him to the other guardians to help him, she tried guiding them to him instead but as he is still alive they can't risk getting close. Tooth is the only one able to safely monitor him and uses that to keep him off of pitch blacks radar.
- Open to interpretation of if he is a halfa or just liminal, maybe as he grows stronger with his powers and learns more about what they actually mean he gains more access to his spirit traits like his hair gets white streaks as he uses his powers or something.
Also up for interpretation if it's a full cross fic with ghosts/the ghost zone/Danny or if it's just an au of half died Jack.
