Batman is really interesting. Their relationship has always been complex, and in a fanfic, they could have a different dynamic. Also, Poison Ivy. Their friendship/romantic relationship is a big part of Harley's story, and exploring it further in a crossover could be great. Another one is Joker. Since he was such a big part of Harley's life, a new take on their relationship in a crossover with other elements could be really engaging.
Wonder Woman would be a very interesting character to cross Harley Quinn with. Wonder Woman represents order and justice, while Harley is chaos. The contrast between them could lead to a lot of great storylines. Deadpool is also a great choice. His fourth - wall - breaking and Harley's own brand of insanity could create a really fun and unique story. And Superman could be an interesting addition. Harley trying to mess with the Man of Steel or even having to work with him would be full of potential.
For a more unexpected villain, how about Lex Luthor? He could see Harley and Deadpool as threats to his plans in Gotham or wherever their story takes place. He would bring his high - tech resources and strategic mind to the table, which would be a different kind of challenge for Harley and Deadpool compared to the villains they usually face.
