One idea could be a time - traveling adventure where the Doctor and Captain Jack team up to stop an alien threat that is disrupting the space - time continuum. They could visit different historical periods and use their unique skills to outwit the enemy.
A plot could revolve around a situation where Captain Jack's immortality becomes a key factor. Maybe there's a disease or a curse that is spreading and Jack's unique condition holds the key to finding a cure. The Doctor, with his vast medical knowledge and problem - solving abilities, teams up with Jack to find the source of the problem and stop it, all while dealing with the implications of Jack's immortality.
Another plot could be that Angelica gets cursed and Jack, with his wits and knowledge of the supernatural, tries to break the curse. They go on a journey filled with strange creatures and difficult challenges. Jack might have to make some tough choices between his own self - interest and saving Angelica.
Another plot could revolve around Teague's past actions coming back to haunt Jack. For example, Teague might have made a deal with a powerful sea witch, and now Jack has to deal with the consequences. Jack could team up with some of his old crewmates or make new allies, like a mermaid who has her own reasons for helping him. This would lead to a lot of adventure on the high seas, with Jack using his wits and charm to get out of tight situations.
Well, obviously the two main characters are the Doctor and Captain Jack. The Doctor, a time - traveling alien with a vast intellect and a love for saving the universe. And Captain Jack, a charming, immortal time agent who has his own set of skills and a rather flamboyant personality.
Another plot could be a time - travel scenario where Jack Sparrow somehow gets sent back in time and has to deal with a younger Captain Salazar before he became so vengeful. This could lead to a complex relationship as Jack tries to change the future.
A plot could be about an alternate universe where Captain Marvel is initially distrusted by the Avengers. She has to prove herself and in the process, they all learn more about each other's powers and pasts. This could lead to some great character development and new alliances within the team.
One idea could be that Eyeless Jack somehow enters the wizarding world of Harry Potter. Maybe he is drawn there by the powerful magic.

One plot idea could be Jack and Ashi exploring a new, uncharted land together. They face strange creatures and have to use their combined skills to survive.

And a third idea is that they have to protect a magical artifact from an evil force, with their relationship growing stronger throughout the adventure.
One plot idea could be that Black Widow and Captain America are on a secret mission together in a war - torn country. They have to rely on each other's skills to infiltrate an enemy base and retrieve a dangerous weapon.

Maybe a plot where they are both framed for a crime they didn't commit and have to work together to clear their names while also uncovering a larger conspiracy within S.H.I.E.L.D.
