It could play a role as a marker of destiny. For example, the character with the snake tattoo is fated to defeat a certain dark force. The tattoo might glow or tingle when they are close to something related to their destiny, like a magical item that will help them in their quest. This way, it acts as a guide throughout the story.
The snake tattoo might also be a form of protection in the fanfic. Maybe it was given to the character by a powerful wizard or witch. When the character is in danger, the tattoo can transform into a real snake to defend them. It could also have the ability to camouflage the character when they need to hide from enemies, making them blend in with the surrounding environment.
The Eryptian could be a guardian of the forest. It might have been there for centuries, protecting the magical creatures and the secrets within. The green snake could be its messenger or helper. Harry Potter and his friends might initially mistake it for a threat but later realize its true purpose.
In some fanfics, the snake tattoo could be a curse in disguise. The person with the tattoo might start to experience strange behaviors like an aversion to certain magical objects or an uncontrollable urge to go to specific places in Hogwarts at night. As the story unfolds, they realize that the tattoo was placed on them by a dark wizard as part of a larger, more sinister plan that involves taking over Hogwarts or stealing a powerful magical artifact.
Snake magic in Harry Potter fanfiction can be used to show a character's dark side. Since snakes are often associated with Slytherin and dark magic in the original series, in fanfiction, a character using snake magic might be on a path towards the dark arts. For example, they could use snake magic to control others or gain power in a more underhanded way.
They could be a source of power. If a character needs a powerful object or potion, the alchemist might be the one to create it. Maybe the alchemist has the ability to create a stone that can grant immortality, like the Philosopher's Stone, but with a different twist in the fanfic. This would attract the attention of both good and bad characters, leading to a complex web of events.
Candy often serves as a plot device in Harry Potter fanfics. It can be used to create magical situations. For instance, a character might accidentally eat a mislabeled candy that gives them an unexpected power for a short time.
In some fanfics, the basilisk can be a source of great power for Harry. He might absorb some of its magic or gain a special ability after a close encounter with it.
In some Harry Potter fanfic, eggs could be used in potions. For example, they might be an ingredient for a magical elixir that gives the drinker a short - term boost of energy. Eggs could also be part of a magical creature's diet. Some fanfic might depict Hagrid using eggs to feed his various magical beasts like baby dragons or hippogriffs.
A bartender in a Harry Potter fanfic can play a really interesting role. They could be the keeper of secrets in a wizarding pub, like the Leaky Cauldron. They might overhear all kinds of gossip and important information from the various witches and wizards who come in for a drink. They could also be a source of magical items or potions that are not easily available elsewhere, sold under the table perhaps.
He could be a time - traveling character. Imagine Rhaegar from his own world ending up in the Harry Potter universe. He could be a key player in changing the course of certain events. For instance, if he has knowledge of a powerful dark magic that is starting to emerge in the Potter world, he might use his skills to counter it.
Well, you could get a tattoo of a character from the fanfic in a unique pose or situation that didn't happen in the original books. For instance, if the fanfic has a scene where Harry Potter is using a new kind of magic, you could get a tattoo of him doing that. Or perhaps a tattoo of the fictional location in the fanfic that was really well - described and has a special place in your heart.
