Another fanfic idea is that his dad is terrified for Adrien's safety. He tries to forbid Adrien from being Chat Noir, which causes a rift between them. Adrien has to then convince his dad that being Chat Noir is important to him and that he can handle the risks. Along the way, they both learn more about each other and their relationship evolves from a strict father - son dynamic to one of mutual understanding and respect.
Perhaps his dad is proud in a strange way. He sees Chat Noir as a powerful figure and now that he knows it's his son, he wants to train Adrien to be an even better 'superhero' but in a way that goes against Adrien's own values, like being more aggressive or self - serving. This could lead to Adrien having to stand up to his father and assert his own ideas about heroism.
One idea could be that his dad initially reacts with shock and disbelief. He might start to question how he didn't notice all the signs before. Then he could try to use Adrien's identity as Chat Noir to further his own business or social standing in some way, creating a lot of internal conflict for Adrien.
On the other hand, it could bring them closer. His dad might start to see Adrien in a new light, as a brave and capable hero. This newfound respect could lead to a more open and trusting relationship between them.
Well, it depends on how much his dad knows about Cat Noir. If he doesn't know much, he might be a bit confused at first. He could ask Adrien what exactly a Cat Noir fanfic is all about. Maybe he'll be dismissive if he thinks it's just some silly fictional thing that distracts Adrien from more 'important' matters. But on the other hand, if he realizes it makes Adrien happy, he might be more accepting in the long run.
Maybe the joke is 'Why is Hawkmoth always so stressed? Because he has too many akumas to manage!'.
One idea could be that Adrien initially feels shocked but also a sense of relief. He might have always had a feeling that Marinette was special, and now it all makes sense. So he starts to view her in a whole new light, with more respect and admiration for her dual identity.
They could also start training together more often. Since Adrien is aware of Marinette's identity, they can practice their superhero skills without the worry of revealing themselves. This would make them a more formidable team. They could learn from each other's strengths and weaknesses, and Ladybug and Chat Noir would be able to defeat akumas more quickly and efficiently.
A good fanfic about their bonding should have well - developed characters. The author needs to show the different sides of both Adrien and his dad. For example, Adrien's dad could be strict but also have a soft side when it comes to his son. It should also have a believable plot. Maybe something as simple as a day at the park where they have a meaningful conversation. The dialogue is key. It should feel natural, like a real father - son conversation.
There is a possibility that it could lead to a better understanding between them. Adrien showing his interest in the Cat Noir fanfic could be a way for his dad to see a different side of him. If his dad is open - minded enough, he might start to respect Adrien's individuality more and this could improve their relationship overall.
He could also start acting out of character. Maybe he becomes more competitive towards Luka. If they are both in a band or something, Adrien might push himself harder to be better than Luka just to get Marinette's attention. He could also be more snappy or short - tempered with Luka, even if he doesn't mean to be.
He might tell his dad the cat pun fanfic because he found it really funny and wants to share the humor. Maybe he read it and just couldn't stop laughing at all the clever cat - related wordplay.
Well, it depends on various factors. If the fanfic is appropriate and within the bounds of legality and good taste, it could be seen as a normal form of enjoying fan - created content related to a character or story he likes. However, if the fanfic involves inappropriate or unethical content, then it would not be normal or acceptable.
