The aliens in the attic could be in hiding from a more hostile alien race. The family living in the house unknowingly provides them with shelter. As the story progresses, the family and the aliens form an alliance to fight off the approaching threat.
One idea could be that the aliens are actually friendly but are misunderstood at first. They came to Earth to learn about human emotions and end up helping the family in the attic deal with their own internal problems.
An old grandfather who lives in the house could be a main character. He has a lot of stories and wisdom. Maybe he has had some previous encounter with aliens when he was young and now he can help the family deal with the situation in the attic. He could be the one to bridge the gap between the humans and the aliens.
Well, there could be a brave kid character. This kid is not afraid to explore the attic and is the first to encounter the aliens. He or she then becomes the bridge between the aliens and the rest of the family.
Perhaps a plot where the human - like aliens are being hunted by an evil organization that wants to study and use their powers. They have to rely on their wits and the help of a few trusted humans. Diamondhead as a human could use his crystal - like skin ability in creative ways to defend against the hunters. And they could also start to question whether they are more alien or more human as they fight for their freedom, which would be a great exploration of identity in the context of this fanfic.
In 'Aliens in the Attic', Jake's love story with the alien could be one of unexpected connection. Maybe at first, they were on opposite sides as the aliens were invading and Jake was trying to protect his family. But as time passed, they might have discovered commonalities. Jake could have seen the vulnerability in the alien, leading to a unique bond that transcended their differences.
One idea could be that aliens come to the Naruto world in search of a powerful energy source. Naruto and his friends initially see them as a threat but then realize they can work together. For example, the aliens' advanced technology could help the ninjas in Konoha with things like healing or building defenses. And the ninjas can teach the aliens about chakra and the importance of honor in battle.
One idea could be an alien oc who has the ability to blend into human society but is on a secret mission to protect Earth from a greater alien threat. Another could be an alien oc with a unique form of communication that causes chaos when humans try to understand it. Maybe an alien oc that is stranded on Earth and has to adapt to human customs in order to survive and find a way back home.
One idea could be that the main character, after being adopted by aliens, discovers they have a special power that is crucial for the survival of the alien race. Another could be that the character has to adapt to the strange alien customs and family structure while also trying to find a way back to Earth. Maybe they also form an unexpected friendship with an alien outcast.
Jake's love for the alien in 'Aliens in the Attic' might develop through a series of events. First, when he encounters the alien, he's likely to be in a state of shock and defense. But as the story progresses, he might find himself in situations where he has to cooperate with the alien. During these interactions, he could see the alien's intelligence and its own kind of beauty. Maybe the alien shows kindness or a different perspective on things. All these aspects combined could make Jake's feelings towards the alien change from hostility or fear to love over time.
One idea could be a story where the monsters and aliens have to team up against an even greater threat from another dimension. Maybe a powerful interdimensional being that wants to conquer both Earth and the alien planets.
