Yandere Bucci Gang by Mental Instability
Mental instability: How normal do they look to society?
1 is you'd think they're normal.
5 is having moments of insanity slip through.
10 is everyone sees a walking red flag.
Trish - Trish is just a normal girl, so she does know how to act in public. Yandere Trish, I imagine as a prima donna. She wants you and she wants to be the center of your world. If it means ruining your life to make that happen, she will. Don't worry, she'll be there to comfort you. However, she'll sabotage your life by ruining your reputation, so I imagine she does need to act as normal as possible.
Giorno - Canonically, most stable because he rarely acts out in public unless there's a dire situation. With Yan!GioGio, I imagine he tries to keep a normal demeanor. As Don, he might have a power trip, but I doubt that would last. He's able to charm people out their belongings, he can totally charm you into believing he's not crazy.
Bruno - Charming guy, but honestly, he is not stable considering his backstory and how he licks people to tell if they're lying. Canonically, he beats people in public and is very nonchalant when his crew was beating on an obvious civilian, even allowing them to stuff the mam with potentially poisonous food. Also, the blurted out that he and his crew was trying to find Diavolo in broad daylight where the enemy can easily spot them. If it wasn't for the fact Bruno is canonically loved by the locals, I would deem him too mentally unstable to be normal in society. Yandere Bruno might not act differently in terms of his private and public antics.
Narancia - Canon Nara is okay. Yeah, he burnt down street and explode cars, but it was in a dire situation. He also freaked out when he realized he was beating on a civilian. With Yandere!Nara, I imagine he's too childish to keep a stable demeanor if you reject his clinginess. He will pout, he will shout, he will lash out. He might also stab. Being delusional does not help.
Mista - Homeboy was randomly stealing people's money outside of theaters, willing to almost die to do so, and boldly stood up against a bunch of armed men. Also, in Trish's body, he was willing to touch private parts in public and blurt out very private information about Trish. Definitely not stable. Yandere Mista is delusional, so he will rationalize his actions of committing violence in broad daylight. He's only in this category because he seems laidback enough to not have people be constantly cautious of him.
Fugo - His outbursts are a problem and in the anime backstory, he warned that his temper gets so bad that it might kill Bruno. Also, Abbacchio had to keep Fugo from going off the deep end with his emotions twice in the anime. Most importantly, we're introduced to him violently beating up his own best friend over being a little shit about math. Then casually apologized as if he and Narancia weren't about to fight to the death. Yandere Fugo still has outbursts.
Abbacchio - Willing to pee in teapots in public, viciously beat a man in public and when he found out the man was an innocent civilian, forced fed the man food to see if it's poisoned. Gonna be honest, Abbacchio does not strike me as stable. Yandere Abbacchio would be plagued with depression and paranoia that you'll be abandon him like so many others have, either through death or being disappointed in him.
I rated both Fugo and Abacchio a 7, but I think Abbacchio's slightly worse. Fugo attempts to be better. Abbacchio actively seeks to act unhinged.
