Another plot point is the character interactions. When Danny meets characters like Asuna or Klein, there are a lot of possibilities for different relationships. Maybe Danny teaches them some of his ghost - fighting techniques, or they help him understand the rules of the SAO game better. These interactions can be really engaging as they bring together two very different groups of characters.
A common interesting plot point is the adaptation of Danny's powers to the SAO world. His ability to go intangible and invisible can create some really unique combat and stealth situations. For instance, he could easily pass through some of the in - game barriers that normal players can't.
A common interesting plot point is the culture shock. Danny, coming from a world where ghosts are more of a local, small - town kind of threat, suddenly being in a world full of magic like Harry Potter's. He has to learn about things like Quidditch and the different houses in Hogwarts. It's like a fish out of water story, but with a supernatural twist.
The team - up of characters from both series is really fascinating. Imagine Natsu from Fairy Tail and Kirito from Sword Art Online working together. They have such different fighting styles and personalities. In some fanfictions, they have to overcome their differences to face a powerful enemy that threatens both of their worlds. This often involves a lot of character growth and interesting dialogue as they learn to trust each other.
In many Danny Phantom singing fanfictions, there's a plot point where Danny's singing is somehow connected to his family heritage. Maybe his ancestors were also great singers or had a connection to music in the ghost world. This connection adds depth to his character and his relationship with his family. Also, when Danny's singing is used to break a curse in the Ghost Zone, it creates a very exciting and unique storyline.
One popular Danny Phantom x Sword Art Online fanfiction is 'Phantom in Aincrad'. It combines the spooky elements of Danny Phantom with the virtual world of Sword Art Online in an interesting way. The story often has Danny navigating through the dangerous floors of Aincrad while using his unique ghost powers.
A great plot point would be if they have to work together to reverse some sort of ghost - related disaster that Jack's inventions accidentally caused. Danny's powers and Jack's knowledge of technology could be the key to fixing it. And along the way, they grow closer as they overcome obstacles.
Another aspect could be the interactions between Danny and his friends while he's sick. His friends might be worried and try to take care of him in their own unique ways. For example, Tucker could bring over some high - tech gadgets to monitor Danny's condition, and Sam could make sure he's eating healthy. Also, the ghosts might take advantage of Danny being sick and weak to cause more trouble in Amity Park.
One possible plot could be that Danny Phantom, while exploring the Ghost Zone, stumbles upon a portal that leads to the Transformers' universe. There, he teams up with the Autobots to fight against a new threat that is related to both ghosts and the Decepticons. For example, a Decepticon scientist could be experimenting with ghost energy to create powerful weapons, and Danny's ghost powers are needed to stop it.
A really cool plot could be that there is a threat to both the Danny Phantom universe and the Sekirei universe. Some sort of dark entity that can traverse between the two worlds. Danny and a group of Sekirei have to team up to stop this entity. The Sekirei can use their combat skills and unique powers, while Danny uses his ghost powers. Along the way, they learn from each other, with Danny teaching the Sekirei about the concept of ghosts and the Sekirei showing Danny different ways of fighting that he hadn't seen before.
Well, a really cool plot is when the Reality Gauntlet starts malfunctioning and Danny gets stuck in a loop of different realities. Each reality has its own set of rules and threats. He has to quickly adapt to survive and find a way to break the loop. This often involves him using his wits more than his powers because in some of these realities, his powers are either weakened or completely different. It's a great exploration of his character growth as he has to rely on his intelligence and understanding of different situations rather than just brute force.
One interesting plot point could be Danny's struggle to find a new power or technique to defeat Pariah Dark. Maybe he discovers an ancient artifact that gives him an edge. Another could be the exploration of Pariah Dark's backstory, like how he became so powerful and evil in the first place.
