One idea could be a crossover with the Borderlands and Mass Effect universes. Handsome Jack could find himself on a mission with Commander Shepard, leading to some hilarious and chaotic interactions as Jack's self - centered and often unethical ways clash with Shepard's more heroic and morally - bound nature.
Another possibility is a crossover with the Fallout series. Imagine Handsome Jack in the post - apocalyptic wasteland of Fallout. He might try to take over some of the factions there, using his charm and devious tactics. Or perhaps he'd be after some unique technology in the Fallout world, causing all sorts of trouble along the way.
A crossover with the Portal series could also be fun. Handsome Jack might be trapped in Aperture Science's test chambers, and his attempts to outwit GLaDOS while still maintaining his pompous attitude would make for an interesting story. He could also try to use the portal technology for his own nefarious purposes back in the Borderlands.
One idea could be a crossover with 'Pirates of the Caribbean' and 'Peter Pan'. Jack Sparrow could find himself in Neverland and have all sorts of adventures with Peter and the Lost Boys. Maybe he'd try to steal the fairy dust from Tinker Bell or have a sword fight with Captain Hook over some hidden treasure on the island.
A Jack Skellington crossover with Corpse Bride would be really cool. Since both are from the realm of the spooky and undead. They could team up to solve some problem in the underworld, like a new threat that endangers both their after - lives. Or perhaps a crossover with Disney's Moana. Jack, being curious about other worlds, sails to Moana's island. He tries to understand their way of life and the magic of the ocean, and in the process, he teaches the islanders about his world of Halloween.
In a fanfiction, Naruto could visit the world of Handsome Jack. Naruto, being his positive self, might be shocked by the chaos and corruption in Jack's world. He could try to use his ninja way to inspire change among the people there, while Jack is both intrigued and a bit threatened by Naruto's pure - hearted nature and powerful abilities.
A good plot for Eyeless Jack crossover fanfiction might be a crossover with a magical realm. Imagine Jack finding himself in a world of wizards and witches. He would be an enigma to them, and his appearance and abilities would likely cause a stir. They might try to either banish him or use him for their own purposes. Another option is a crossover with a horror - comedy universe like "Ash vs Evil Dead". Jack's serious and menacing nature could create some really funny and tense situations when contrasted with the more over - the - top and comical elements of that universe. Also, a crossover with a time - travel story could be interesting. Jack could be sent to different time periods and have to adapt to the different cultures and threats in each era.
A possible plot could be that Jack the Ripper's true identity in the fanfiction is actually a corrupted form of an otherwise noble Servant. Maybe he was a heroic figure in the past but was corrupted by a powerful dark magic. A group of Fate characters could then be on a quest to find a way to reverse this corruption. They would have to face not only Jack the Ripper's deadly attacks but also the political and social unrest in the London setting of the story. The fanfiction could also explore the psychological aspect of how the Ripper's mind works and how the Fate characters react to his extreme violence.
One idea could be that Johnny Bravo accidentally travels to the world of Samurai Jack. He tries to use his charm on the various strange creatures there, but it doesn't work as expected. Meanwhile, Samurai Jack is initially confused by this strange, over - confident man but then realizes they can work together to fight Aku.
A crossover with the Jason Bourne series could also be cool. Picture Jack Ryan and Bourne on the run from a shadowy government agency that they've uncovered is involved in illegal and unethical operations. They have to use their wits and combat skills to expose the truth and take down the bad guys.
Lara Croft would be an interesting character to pair with Handsome Jack. She's a strong - willed and adventurous archaeologist, and her no - nonsense attitude would contrast with Jack's over - the - top personality. Their interactions could involve Jack trying to steal some ancient artifact that Lara is protecting, leading to a battle of wits and skills.
It could be really wild. Naruto's world is full of ninjas, spirits, and elemental powers, while Handsome Jack is from a high - tech, dystopian setting. In a fanfiction crossover, we might see Naruto using his Rasengan against Jack's laser guns. Jack might be baffled by Naruto's ability to run up trees and walk on water.
The contrast between the two characters. Handsome Jack is this complex, often villainous character, while Maya is a strong and heroic Siren.
