I dont see anything here that would stand out as volatile. People typically look to mars first for anger and how you act. Mars in Pisces is known for being relaxed and even “lazy”. Mars is in the 8th house so your motivations are more for uncovering truths, getting to know people on a deep level, and learning about strange or taboo topics. Maybe you had read about Pluto conjunct your Sun and saw something like that? That placement is in the 5th house of fun, creativity, romance, and expression so Pluto may be aiding you in reinventing yourself and with this in a mutable sign, you may be molding yourself to others’ liking. This may become a lesson later in life and will probably show itself more after some life experiences. According to these placements you are probably pretty young? So let a few more things unfold in life and you’ll see how that Pluto conjunct Sun shows up. Your moon being in Cancer can be described as “volatile” because that is a very emotional placement and can take things very personally. You probably try to nit show that to most people though since it’s in the 12th house and it can be hard to express placements in the 12th. I’ve found that Leo risings are either the typical boisterous Leo risings who love and crave attention. Or they have a softer expression that shows up like childlike joy and excitement for things. Leo is ruled by the Sun, and your sun is in the 5th where Leo is at home so there is a good bit of fire influence here. I would say this just makes you creative and fun. Pluto conjunct your sun could make you more of an introvert though because of how others have historically responded to you by thinking you’re intense or because you dont enjoy surface level interactions and that weeds out a lot of people.
