One idea could be that they both get kidnapped by a mad scientist who wants to study their unique mental states. They then have to team up to escape the scientist's lair.
Maybe they accidentally switch powers or personalities. Deadpool becomes more like Harley and Harley becomes more like Deadpool. This would lead to a lot of comical situations as they try to figure out how to reverse it while also dealing with their enemies who are confused by the change. For example, Harley with Deadpool's regeneration ability might use it in really unexpected and funny ways. And Deadpool with Harley's acrobatic skills would be quite a sight to see. They would also have to learn about each other's lives and pasts in a new way as they experience these changes.
Another plot could be that they are both hired by a powerful crime lord to steal a valuable artifact. But they both have different motives for taking the job. Deadpool might be doing it for the money or just for the fun of it, while Harley might be trying to get revenge on the crime lord for something he did to the Joker. Along the way, they face many obstacles and have to decide whether to trust each other or double - cross each other.
One idea could be that Harley Quinn and Deadpool team up to take on a common enemy in Gotham City. Maybe a new super - villain who has a plan to take over both the criminal underworld and the hero world. They could have a really chaotic and funny dynamic, with Harley's zany antics and Deadpool's fourth - wall - breaking humor.

One plot idea could be that Deadpool and Harley Quinn team up to take on a common enemy, like a new super - villain in Gotham who has a connection to some of Deadpool's foes. They could start off not getting along because of their different personalities, Deadpool's fourth - wall - breaking and Harley's chaotic - cute nature. But as they face challenges together, they learn to work as a team and even become friends.
One idea could be that they are both transported to an alternate dimension. In this dimension, all the rules are different. Deadpool's healing factor doesn't work as well, and Harley Quinn's usual weapons are useless. They have to rely on each other's skills and knowledge to find a way back home. Along the way, they meet strange versions of their friends and enemies, which adds to the hilarity and confusion.

A possible plot for a Poison Ivy and Harley Quinn fanfic could be that they are framed for a crime they didn't commit. They then have to go on the run from the law and Batman. As they are running, they discover a secret underground garden that has plants with magical properties. Ivy wants to study these plants, but they also have to be careful not to be caught. Meanwhile, Harley is constantly cracking jokes and getting them into even more trouble, but also helping them out in unexpected ways.
The potential for humor. Both characters have a great sense of humor in their own ways. Deadpool's sarcastic remarks and Harley's off - the - wall comments can make for some really funny exchanges in a fanfic. For example, they could be in the middle of a fight and still be cracking jokes at each other. Also, the fact that they are both anti - heroes gives the writer a lot of room to play with moral ambiguity in the stories.
Well, for one, it's the potential crossovers. Since they are from different comic universes, fanfic writers can create all kinds of scenarios where the rules of both universes are bent or combined. Also, their individual quirks make for great storytelling. Harley's love for the Joker and her own brand of mayhem, paired with Deadpool's non - stop chatter and disregard for norms, can lead to some truly engaging and unique plots that can be both hilarious and action - filled.
