His deep voice might make his friends initially think he's being possessed or something's wrong. They could be a bit scared or hesitant around him at first.
In the wider ghost - fighting community, his deep voice could give him a more authoritative presence. Some might respect him more because of it, while others might see it as a sign of him being different and potentially dangerous. This could lead to new alliances and rivalries within the community.
One idea could be that Danny's deep voice is a result of a new ghost power he acquires. This power makes his voice so deep that it can paralyze enemies. He has to learn to control it while also using it to his advantage in battles against powerful ghosts.
In Danny Phantom fanfiction, heat might affect Danny in various ways. For example, his ghost powers could be weakened as some fanfics might play with the idea that extreme conditions like heat disrupt the balance of his human - ghost hybrid state. It could also make it harder for him to stay invisible or intangible as his energy is being sapped by the heat.
If Danny gets new powers like telepathy, it might make his relationships with his friends a bit strained at first. His friends might feel that he's invading their privacy when he accidentally reads their thoughts. But over time, they could learn to trust him with this new power. With his enemies, new powers would make them more afraid of him, which could either lead to more intense battles or some enemies trying to form alliances with him out of fear. For example, a mid - level ghost who was previously neutral might side with Danny to avoid being on the receiving end of his new powerful attacks.
In some fanfictions, Danny's mom might find out when she accidentally witnesses Danny transforming into his ghost form. Maybe she walks in on him at a crucial moment.
Danny's powers could be a huge asset. His intangibility could help him and Batman get into places that are otherwise inaccessible. His flight would give them an edge in chasing villains across rooftops. Also, his ghostly energy blasts could be used as a new form of weapon against the bad guys in Gotham.
His powers might also make Jason more protective. Knowing that Danny is different and has these abilities that could be exploited, Jason would be extra vigilant. This could lead to some arguments as Danny might feel smothered at times, but overall it would show how much Jason cares about him and is willing to go to great lengths to keep him out of harm's way.
His ghostly wail, a very powerful attack, could be used as a last - resort weapon against powerful foes in the Batman universe. However, it also might attract unwanted attention from other supernatural entities. Danny would have to learn to control it better in the more urban and populated Gotham. This would add an interesting dynamic to the crime - fighting in Gotham as they would have to deal with the potential consequences of using such a powerful ability.
In fanfiction, the idea of Danny and Ember having a daughter can lead to really interesting storylines. Maybe their daughter could inherit Danny's ghost powers and Ember's musical abilities, creating a unique character. She could struggle with being half - ghost, half - something else due to Ember's unique nature, and have to find her place in both the human and ghost worlds.
Danny would probably be heartbroken. He really cares about Sam, so finding out she cheated would be a huge blow. He might go into a state of denial at first, not wanting to believe it.
Danny's relationships change drastically. He distances himself from his friends and family. He no longer values their opinions or support. Instead, he might see them as obstacles or even threats. His friendships with Sam and Tucker are strained as he starts to engage in activities that they find morally wrong, like using excessive force on other ghosts or humans who get in his way.
