Another fanfiction concept could be that Peter Parker discovers the existence of the Ghost Zone. Danny could be his guide there. Together, they explore the strange and dangerous realm, facing off against powerful ghost entities. Along the way, Peter learns about different types of ectoplasm and how it can be used, similar to how he studies different scientific concepts in his own world.
One idea could be that Danny Phantom gets transported to the Spider - Man universe. He could use his ghost powers to help Spider - Man fight villains that are a bit more supernatural in nature, like Mysterio when he's using his illusions. Danny could phase through objects to avoid attacks and then surprise the bad guys.
Maybe there's a crossover where the symbiote from the Spider - Man universe attaches itself to Danny Phantom instead of Peter Parker. This would create a whole new set of challenges for Danny as he has to deal with the aggressive nature of the symbiote while also using his ghost powers. He might end up looking like a really cool, spooky version of Venom.
