Memory - enhancing tattoos are also possible. The tattoo artist could create a tattoo that, when activated, allows the wearer to relive a specific memory. It could be like a Pensieve but on your skin, perhaps a tattoo of a significant event in the wizarding world.
Ask around in Harry Potter fan groups. There are many online communities where fans discuss all things related to the series. Someone might have had a similar tattoo done and can recommend an artist. You can also check out local tattoo parlors and ask if any of their artists are fans of Harry Potter or are open to working from fanfic concepts.
Tattoo artists should communicate and explain to their clients and provide professional advice. Tattoo artists could give customers reasonable advice on the location, size, pattern, and other aspects of the tattoo to help customers make wise decisions. If the client requested a tattoo on an awkward part, the tattoo artist should respect the client's wishes and provide professional services as much as possible.
They could also have a connection to his emotions. In fanfiction, perhaps when Harry is feeling angry, the tattoos might darken or become more prominent. When he is happy, they could shine brightly. This connection between his emotions and the tattoos could be a way for him to better understand himself and also for others around him to gauge his mood without him having to say a word. And the tattoos could potentially attract certain magical energies based on his emotional state, further affecting his magic.
In fanfic, tattoos can have magical properties. A tattoo of a magical object, say the Elder Wand, might give the wearer some power related to the object. It could also be a form of protection. If a character has a tattoo of a powerful charm, it might protect them from certain dark magic. Moreover, tattoos can be used to tell a character's backstory. A character with a tattoo of a certain place in the wizarding world might have had an important experience there.
One interesting fanfic could be 'The Ink of Hogwarts'. In this story, the tattoo artist has a special connection to the wizarding world. They use their magic-infused ink to create tattoos that can have real magical effects on the wearer. It's a really cool concept that combines the art of tattooing with the magic of Harry Potter.
Well, it could be that the magical tattoos are a form of protection. Just like how Harry had the scar which was a connection to Voldemort, these tattoos could be a positive connection to some other powerful magical force. They might be given to him by a powerful wizard or witch who saw his potential. And they could change and grow as Harry himself grows in power and knowledge. For instance, a simple star tattoo could expand into a constellation as he masters more spells.
Well, perhaps the tattoos could be a mark of a secret society within the wizarding world that Harry gets involved in. They might give him special powers or knowledge.
Hermione could be into nature - inspired tattoo styles. Since she loves books and knowledge, she might design tattoos of magical plants like the Whomping Willow or the Mandrake. These tattoos could have a touch of magic where they seem to sway or make sounds like the real plants in certain situations.
Another idea is that the tattoo artist uses the essence of magical creatures to create tattoos. For example, a phoenix - inspired tattoo might give the wearer the ability to be reborn from ashes in a symbolic way within the story. This combines the art of tattooing with the rich mythology of Harry Potter.
It could be a wizard who is an outcast from the mainstream wizarding society and has made a living by using his magic in unconventional ways, like tattooing. He might have a small, hidden shop where only those in the know can find him.
