I saw fan art a while ago of the Kawajiris with killer queen and stray cat and it had the caption of something like "a perfectly normal family with their totally normal cats" or something like that. I just thought that was pretty funny haha.
Stands that have their own personalities are so fun. Like sex pistols, spice girl, stray cat, etc. Kinda wish there was more but it also makes it really fun when one shows up once in a while.
Edit: also I just thought of this but I didn't want to double post. But one of my fave dynamics in jojo is the one where two people on the protagonist side just do not get along. I always think those are really fun and add a unique spin to the dynamic of the main cast. Like Rohan and josuke, or abbacchio and giorno. Or even Diego and Johnny even though Diego isn't a part of the group but I still think that counts. None of these are my fave dynamic from that part's cast, but they're just funny to me
