There are a lot of things about Melone I can talk about but let's take a moment to look at the way Melone refers to his stand. First, Baby Face is referred to as a parent. The stand that is active and pursuing is a "son of baby face" implying a difference in the stand that created it and the stand that is active. He also refers to the stands baby face creates as stands and uses the term sons. This could be just in the translation but the idea comes across often that there is a separation between the initial stand Melone uses to create baby face and the "son" the stand creates. Second, Melone talks about baby faces ability as an auto tracking stand in words that imply this isn't the consistent result. It's referenced at another point that the stand relies on how much it's learned and he's also given an option to use a "father" of sorts. All this implies a lot of variety between the "sons of baby face" which could occure. Third, Melone has to teach his stand. This is really interesting seeing as the stand is both sentient and growing independently of himself. Baby Face acts on its own and seems to inherit from its mother and "father" rather then from its user. Because of these points I find it likely that the stand that shows up first and allows the creation of baby face is Melone's true stand while baby face operates under the stand the stand that we see in Melone's chapters is only partly his. This is important if one takes stands as reflecting the users inner working. This theme runs strongly throughout Vento Aureo and Giorno references it during the fight with Cioccolata. If stands reflect the user then the part of Melone's stand that can be used to determine more about him is the initial data collecting computer element. The stand that does the fighting tells us more about its parents. Melone comments that the personality is different each time and suggests using a different mother the next time. The ability we see Baby Face use could also change but there isn't any strong evidence supporting this in either direction. This being the case we can only look at the stand Melone uses early on and the features we know for sure all of baby faces sons would have. First, The stand asks for dna contribution which activates the auto tracking implying it could be possible to use baby face without this ability. The ability itself sets the stand to track it's "father" while baby face seems to consumer it's mother following birth. This is likely a reflection of an extremely unhealthy relationship with his own parents. Searching out a father could relate to having an absent father. The consumption of the mother is a little more difficult to say for sure but it is unhealthy no matter what. Second, the stand is a computer based stand that analyzes data of humans and genetics. Melone needs to input blood types and ages as well. He also asks questions about drug and alcohol use. All these presumably affect the outcome. From this it's clear he has some base knowledge in genetics, and the impact of environment on the fetus, likely also epigenetics. The entire time he is questioning the "mother" he remains distant and cold for the most part. This isn't something he does for any pleasure outside of the use of his stand and a scholarly side. He has the mind of a scientist without many morals. If he has to sacrafice some people for his experiment he will. I could honestly go on for much longer about Melone and what his stand could say about him but I'll expand in a later better organized post. Anyhow for now have some observations and feel free to ask me about my interpretations any time
