His friends Sam and Tucker could be the ones to save him. They are always there for Danny and they might come up with a clever plan using their knowledge of technology and the supernatural world to break into Walker's prison and rescue Danny.
Well, in such a fanfiction, Danny Phantom might be in a really tough situation. Walker is a powerful foe. He could be locked up in Walker's prison dimension, facing all kinds of strange and dangerous inmates. Maybe he'd be trying to find a way to escape using his ghost powers, but Walker has probably set up all sorts of barriers to prevent that.
Yes, there are quite a few. You can start by checking out fanfiction websites like FanFiction.net or Archive of Our Own. Just search for 'Danny Phantom x Walker' and you'll find a variety of stories. Some might focus on their unlikely friendship, while others could explore more complex relationships or adventures they could have together.
Danny might react with panic at first. After all, he has been hiding his identity from his parents for so long. He could try to escape from them, using his ghost powers in a desperate attempt to get away before they can do anything drastic.
One popular story could be 'The Haunting Alliance'. It features Danny Phantom and Walker teaming up in a unique situation. Another might be 'Walker's Redemption' where Walker has a change of heart in some way. And 'Phantom in Walker's Realm' which explores what happens when Danny gets trapped in Walker's domain.
He might meet a nurse who has some sort of psychic ability and can sense that Danny is different. This could lead to an interesting interaction where Danny has to be extra careful.
You can also try some Danny Phantom - dedicated forums. Sometimes, fans will post their own fanfiction there or recommend good ones they've read. Additionally, Tumblr might have some posts related to Danny Phantom x Walker fanfiction. You can search for relevant tags like #DannyPhantom #Walker #fanfiction.
It could be one of his enemies. For example, Vlad Masters. He has always been envious of Danny and would love to see him in trouble. Exposing Danny's secret would be a great way for him to get back at Danny and take over Amity Park.
First, know the characters well. Danny is brave and has his unique powers, while Walker is strict and rules - bound. Then, come up with an interesting plot, like a mystery in the Ghost Zone they have to solve together. Also, add some unique elements, such as new ghost powers or a new area in the Ghost Zone.
Perhaps Danny's friends find out that he has been caught by his parents. They could come to his rescue. Tucker might use his tech - savvy skills to hack into the Fenton's security systems, and Sam could try to reason with Danny's parents. Together, they could try to convince Danny's parents that Danny is still the same person they love, just with some extraordinary powers.
Obviously, the main character would be Danny Phantom himself, but in two different forms or versions. One would be the original Danny Phantom from the canon source, and the other would be a version created by the fanfiction. There might also be his friends like Sam and Tucker who could play important roles in helping the two Dannys understand each other and deal with any issues that arise from their meeting.
