Hoo boy, where to start? Well, I'll keep the فہرست short.
I'd want to meet Yzma the most because she'd be extremely fun and I can see getting along with her very well in a friendly setting. If she wasn't available I'd pick Ursula for the same reasons and because I crush hard on her. If not Ursula, then Hades because he's also fun and I sympathize with him. Lastly that I'll mention, Captain Hook because I REALLY sympathize with him and would love to help him off Pan.
Do the modern villains count? If they do, my first choice would be Hans. We have a lot in common (hope nobody interprets that the wrong way), so I think we'd probably get along really well. But if he doens't count, I'd probably go with Captain Hook یا the Queen of Hearts.
