Another idea is to base the OC on a different species from the Marvel universe. Maybe an OC from a long - forgotten planet that has its own reasons for getting involved in the fight against Thanos. This could bring in new cultural elements and backstories to the fanfiction.
You could also get inspired by the relationships in Infinity War. Have your OC be a long - lost friend or relative of one of the main characters. Their presence could add an emotional layer to the story, like if they were a sibling of Tony Stark who had been missing for years and suddenly shows up to help in the battle against Thanos.
One inspiration could be to focus on an original character's unique abilities. For example, if your OC has the power to manipulate time, they could be in a race against it during the events of Infinity War. They might try to stop Thanos before he gets all the Infinity Stones by using their time - altering powers in creative ways.
Another idea is to base the fanfiction around the power struggle for the Infinity Stones. Your OC could be a new player in this battle, having unique abilities that make them both a target and a key figure. They might team up with some of the well - known Marvel characters like Iron Man or Captain America, but also have their own motives and secrets related to the Stones.
Maybe an alien from a planet that was previously unmentioned in the MCU. This alien OC has a special connection to the power of the Infinity Stones and teams up with Thor because they realize that Thor is a key figure in the battle against Thanos. Their knowledge of the Stones could be crucial in the fight.
To make the plot compelling, introduce some mystery around your OC. For example, they could have a hidden past or a secret power that is gradually revealed throughout the fanfiction. This will keep the readers guessing and eager to find out more. You can also create some unexpected alliances. Maybe your OC teams up with a villain from the movie for a common goal, which goes against the expected alliances in Infinity War. This can add an interesting twist to the plot.
Another theme is the OC's relationship with the established Avengers characters. Some fanfictions focus on the OC forming friendships, romances, or rivalries with the likes of Iron Man, Captain America, etc. It adds a new layer of drama to the Infinity War story. For example, an OC might start off as a fan of Tony Stark and then end up having to work with him during the war. The dynamic between them can be very interesting.
Another way an oc can interact with the Infinity Stones is by using their own unique abilities or skills to harness the Stones' power. For instance, if an oc has the ability to manipulate energy, they could use that to better control the power of the Infinity Stones. They might also be able to create devices or spells that enhance their connection to the Stones, allowing them to use the Stones' power more effectively in different situations.
One interesting concept could be how an original character (OC) interacts with Thor during the events of Infinity War. Maybe the OC has a unique power that helps Thor in his quest against Thanos, like being able to manipulate time briefly to give Thor an advantage in a battle.
One great 'Avengers Infinity War OC fanfiction' is 'The New Hero in Infinity War'. It features an original character who has unique powers and gets involved in the events of the movie in an interesting way. The author does a great job of integrating the OC into the existing storylines.
One idea could be creating an OC (original character) who is a powerful mage from a hidden dimension. They could have unique powers that disrupt Thanos' plans in unexpected ways. For example, their magic could nullify the power of the Infinity Stones temporarily.
In Infinity War fanfiction, Loki can be alive. Fanfic authors have the creative liberty to rewrite the events. They might bring Loki back to life using magic or some other means. For example, Loki could have faked his death and gone into hiding, only to reappear later in the story to help the heroes fight against Thanos. His survival can add an interesting twist to the story and create new interactions between characters.
Well, it would be much more light - hearted in many ways. The Cartoon Network characters have a different style of humor and action compared to the serious and often dark tone of the original Infinity War. For instance, the Powerpuff Girls would bring a sense of girl - power and sassy dialogue, which is quite different from the brooding heroes in Marvel's Infinity War.
