I think it would be so cool if Harley got influenced and became the right hand of another villain instead of the Joker
Ivy would be the most obvious choice for this given her long history and romance with Harley and I could totally see them being an eco terrorist power couple
Harley and Jonathan being together or teaming up would be neat because their both psychiatrists who know Arkham Asylum really well and I could see them using fear and psychological conditioning to bring corrupt politicians and business owners to their knees
I think Harley and Waylon being together would be interesting because they already know each other through Ivy and I could see Harley understanding Waylon with his family issues and being an outsider and they could be a good duo
Harley and Ed being friends has also been a fun idea that DC should do more with and I think they would totally do a bunch of crazy traps and puzzles to annoy Batman
Harley and Jervis is mainly self indulgence because they’re two of my favorite rogues but I could see Harley understanding Jervis’s mental struggles and being fascinated by his delusions and charmed by his captivating storytelling and becoming his new “Alice”
I don’t see Oswald being in Arkham but I could see Harley being hired as a mob psychiatrist so Oswald can keep an eye on some of his more unstable colleagues and Harley would be Oswald’s friend and right hand but they wouldn’t really date and be friends
Harley and Victor would nice because I could see them more as friends and lab partners instead of anything romantic and I could also see Harley help Victor with his trauma related to what happened to Nora and I could also see them being anti heroes, helping people either rare mental and physical diseases but they would have really unethical ways of doing things
I love Harley and Ivy and Selina and Bruce but I think these two be a pretty interesting couple, because they are already really close friends in canon and I could see them getting into all sorts of trouble and they would be best pet moms with the cats and Bud and Lou
Any of these would be fun duos and ways to make some strange but also awesome character changes
