One idea could be an OC who is a brilliant scientist that discovers a new weakness in the alien technology just in time for the Independence Day battle. Another could be an OC who is a pilot from a small town and has to step up and fight the aliens, bringing a sense of hometown heroism to the story. Maybe an OC who is a diplomat trying to negotiate with other countries during the alien invasion to unite the Earth's defenses more effectively.
Well, you could have an OC who has some sort of psychic ability. They sense the aliens' plans before they happen. This OC could then work with the military to try and thwart the invaders. Or an OC who is an artist. They use their art to inspire the survivors during the chaos of the alien invasion, giving people hope. Also, an OC who is a mechanic could modify existing vehicles to be more effective against the aliens.
One idea could be to write about an alien invasion on Independence Day but with a twist where the ordinary citizens use their knowledge of American history and values to outwit the aliens. For example, they might use the concept of unity from the nation's founding to band together in a way the aliens don't expect.
Perhaps the heroes discover a plot by a super - villain to use the patriotic fervor of Independence Day to his advantage. He plans to brainwash the population using a mind - controlling device disguised as a fireworks display. The young justice team has to figure out how to stop this without ruining the holiday spirit for everyone.
One idea could be that the OC is a long - lost relative of one of the main characters in 'knight and day'. They show up unexpectedly and have some special skills or knowledge that helps in the adventure. For example, they might be an expert in a certain type of martial art that is useful against the villains.
One idea could be to create an OC who is a time - traveling medic. They could cross paths with the Doctor during the 'day of the doctor' and use their unique medical skills to help in a crisis. Maybe they have a device that can heal wounds in a different way than the Doctor's sonic screwdriver.
The story is about the return of the alien invaders. Earth has rebuilt and advanced its defenses since the first invasion. However, the aliens come back with more powerful technology. The heroes from the first movie, along with a new generation, have to once again fight to save the planet from destruction.
You could create a time - lapse video of the Independence Day fireworks and add the text 'Happy Independence Day' with some emojis like the flag emoji. Another option is to share a picture of a historical site related to the independence of your country and give a brief description about its significance along with the 'Happy Independence Day' wish.
One of the great Independence Day stories is about the signing of the Declaration of Independence. The Founding Fathers put their names on that document, fully aware of the risks. It was a bold step towards freedom from British rule. Thomas Jefferson played a huge role in drafting it, and it was a statement that would change the course of American history.
Another plot could revolve around an OC who is a Spartan trainee that doesn't quite fit the mold. They have a different way of thinking and approaching combat. In Halo 4, they end up being the key to solving a mystery related to the Prometheans. Maybe they find a way to communicate with the Prometheans and convince some of them to stop fighting the humans.
One idea could be an Otsutsuki OC who comes to Earth not for conquest but to study the unique life forms here. They could befriend some of the local ninjas and learn about the concept of friendship, which is alien to the Otsutsuki. This would lead to a series of adventures where they have to protect their new friends from other more hostile Otsutsuki members.
One idea could be an OC who is a long - lost relative of Moana. This OC could have been separated from the family during a great storm years ago. They could have unique skills, like being able to communicate with a different type of sea creature that Moana has never encountered. This would bring new adventures as Moana and the OC try to figure out how this new discovery could help their island.
