The idea of Percy having a secret girlfriend in fanfiction can open up a whole new world of character development. If his girlfriend is a new character introduced in the fanfiction, she could have unique powers or abilities that complement Percy's. Their secret relationship could be a way to explore Percy's more private and vulnerable side, away from his usual heroic adventures.
His secret girlfriend could be in a difficult situation herself. Maybe she's a demigod with a dangerous family or past. Percy is trying to help her while keeping their relationship a secret. This could involve them sneaking around to meet, sharing secret glances in public, and having to communicate in coded ways. It would create a really interesting and suspenseful plot.
It could be Misty. They have a long - standing relationship in the Pokemon series. They've traveled together and shared many adventures, so in a fanfiction, it's not a stretch to imagine her as a secret girlfriend.
In some fanfictions, it could be a character from another magical school. Like a girl from Beauxbatons or Durmstrang. She might have met Harry during an international magical event and they've been secretly seeing each other ever since.
Maybe it's a new character created specifically for the fanfiction. A girl from a far - off region who Ash meets during one of his journeys. She could be a powerful trainer or have some special abilities that draw Ash to her, and they start a secret relationship.
It could be a Muggle - born witch who he meets outside of Hogwarts during the summer holidays. She's not part of the typical wizarding society he's used to, so they keep it a secret as it's an unusual situation for a wizard like Harry to be involved with a Muggle - born in such a way.
It could be a mark that represents his family or a long - lost heritage. Perhaps it's a crest that has been passed down through generations in his family but he has to keep it secret for some reason, like it might draw unwanted attention from certain enemies or factions in the story.
Perhaps the tattoo has a special meaning that he wants to keep private. It could be related to a personal journey or a relationship that he doesn't want others to interfere with. For example, if it's a tattoo related to a past love or a mentor who taught him a valuable but forbidden skill. The knowledge of the tattoo could expose these things and he wants to protect them.
The plot could be that Percy's girlfriend is a time - traveler. She comes from the future and warns Percy about a great danger that is going to befall his world. Percy is initially skeptical but soon realizes she is telling the truth. They then embark on a journey to stop this danger. Along the way, their relationship deepens as they rely on each other's strengths. Percy uses his combat skills and the girlfriend uses her knowledge of the future to outwit their enemies.
Well, it could be really interesting. Maybe Ash in this fanfiction is from a well - known series, like Pokémon. His secret girlfriend could be someone he met during his travels. It might add a whole new layer of drama and romance to his adventures, changing the way we see his character.
