The plot might involve Barty helping Harry with his studies. Since Barty is a rather intelligent wizard, he could teach Harry some advanced magic spells and techniques. They start as acquaintances but gradually become friends as they spend more time together in the library, poring over old magic books.
Well, it could be about Harry and Barty getting to know each other through a shared interest in magical creatures. Maybe they meet in the Forbidden Forest while Harry is on detention and Barty is secretly researching a rare creature there.
Harry is the central figure around which the story often revolves. He is curious and brave. Barty, in this context, becomes an important counterpart. He is intelligent and has a certain charm that draws Harry towards him. There could also be other minor characters like Hermione and Ron who might be initially suspicious of Barty but gradually accept their friendship.
Perhaps a fanfiction where Barty, after being exposed, somehow has a chance at redemption and forms an unlikely alliance with Harry to fight a greater evil that threatens the wizarding world. They could learn from each other's strengths and weaknesses. For example, Harry's pure heart could influence Barty to turn away from his dark past.
Sirius Black would be an interesting character to put in the fanfiction. He has his own history with the dark arts and could offer a different perspective on Barty's actions. And Neville could also be included. His growth and courage could inspire both Harry and Barty in different ways. Neville might stand up to Barty in a situation where others might not, showing his new - found confidence.
Another plot could be a time - travel fanfiction. Harry and Barty Crouch Jr. are sent back in time to a crucial point in wizarding history. They have to work together, despite their differences, to fix something that went wrong in the past. This would force them to understand each other better and perhaps even form an unlikely friendship.
The relationship could start with hostility. Harry, knowing all the bad things Crouch Jr. has done, is full of hatred. But as the story progresses, he could learn about Crouch Jr.'s tragic backstory, which might make him more empathetic.
Well, one interesting plot might be a time - travel fanfiction. Barty Crouch Jr goes back in time to prevent himself from ever getting involved with Voldemort. This could lead to a whole different series of events in the Harry Potter universe. Maybe he ends up becoming a key figure in fighting against the Dark Arts in a more positive way. He could also have an adventure where he teams up with other characters who were previously his enemies in the original timeline, like the Aurors, to take down some new dark threat.
The person who killed Barty Crouch in fanfiction is highly unpredictable. It could be a dark wizard who emerges from the shadows or a close ally with a hidden agenda.
Well, there's a fanfiction called 'Barty Crouch Jr: A Different Path'. In this one, the author imagines what would have happened if Barty Crouch Jr had not followed Voldemort. It gives a whole new perspective on his character. Also, 'The True Nature of Barty Crouch Jr' is really interesting as it tries to uncover the real motives behind his actions in the original story.
Bartemius Crouch Junior was a character in the Harry Potter series by British author J. K. Rowling. He was the second son of Barty Crouch, the Director of International Magical Exchanges and Cooperation, a pale, pale-haired young man who was also a Death Eater and Dark wizard. As a teenager, he became a loyal follower of Voldemort, and together with Bellatrix Lestrange and Rodolfo Lestrange, he tortured Neville Longbottom's parents, leading to their arrest and life imprisonment. After he was arrested, his mother begged her husband to save him on the condition that she was dying, and he became the first person to escape from Azkaban Prison in recent history. In the 1994 - 95 school year, he disguised himself as Mad-Eye Moody as the Defense Against the Dark Arts professor at Hogwarts, manipulated the Triwizard Tournament, and assisted in the resurrection of Voldemort. He kept Moody in a box with seven locks, and used Moody's hair to make Polyjuice Potion to maintain his disguise. Later, his identity was exposed, and he was kissed by a dementor brought by Cornelius Fudge and lost his soul. He had a close relationship with the Lestrange family, and they had tortured the Longbottoms together. During the trial, he firmly denied his crimes and begged his parents to save him but failed. Many believed that he had been neglected by his father, and that Crouch Sr. had been too focused on promotion to spend much time with his family. He had escaped Azkaban because his mother had used Polyjuice Potion to make him look like him, and her mother had died alone in prison. During the Quidditch World Cup match between Sofia and Iceland, he had sat in the seat next to his father in the Invisibility Cloak (accompanied or watched by Winky the house-elf), then had broken free of the Imperius Curse, taken Harry's wand, and fired the Dark Mark to create chaos. In addition, there are many clues in the novel that suggest that he is pretending to be Mad-Eye Moody, such as Mad-Eye Moody's performance in the first class, the explanation of the Goblet of Fire incident, the nervous twitch, Winky's strange behavior, and the Dark Magic detector. In the Harry Potter movies, Barty Crouch Jr. was played by David Tennant. Harry Potter and the Goblet of Fire was not enough. Everyone, please click to read the novel!

Along the way, they face some magical creatures protecting the plants and they have to use their combined skills of magic and Neville's knowledge of plants to get through. It could strengthen their friendship as they rely on each other.
