Dio is consistently manipulative and violently domineering, and has repeatedly shown a lack of conscience and empathy. Dio's most recognizable characteristics are his boundless ambition and his love of power. Abused by his father and having lived in the most miserable living conditions,[20] Dio set for himself the goal of becoming the richest, then the most powerful being on Earth. To do so, Dio used anything or anyone that he could in order to further his goals, disregarding any kind of morality that would restrain the range of actions available to him. Using either manipulation, seduction, or plain violence, Dio constantly sought to become more and more powerful. Dio enjoys being in a position of power[13][21] and has repeatedly stated how great he felt being in a dominating position. On the contrary, Dio never tolerated that someone could stand up to him or equal him in power, and was enraged and deeply disturbed at the thought several times. Throughout his life, Dio has tended to surround himself with witless cronies and later minions, who were attracted by his natural charisma. Not thinking much of them at first, he then selected those he deemed as particularly evil, claiming that an evil person wasn't bound by rules such as honor[22] and thus were stronger mentally. This belief culminated in including the absorption of 36 souls of sinners, or, as he claims, particularly strong souls, to unlock a power greater than that of his Stand, The World. Naturally, Dio is an incredibly-selfish person, only looking over his own interest and overlooking those of others at best, trampling them on the ground at worst. Due to his composed nature, Dio can and will manipulate and take what he can from all sorts of people, using any method, as long as the person suits his present desires because he is primarily interested in their capabilities. Dio is the type who is incapable of loving another person wholeheartedly. When interacting with someone, Dio will constantly try to manipulate them and sway them into his side, using a veneer of gentleness and his natural charm to make people admire and like him. For instance, he acted the model son and popular charismatic friend to Jonathan's father and entourage to better isolate him, and as a vampire, his charisma only increased as he appeared as a charming mysterious individual. However, his natural arrogance would lead him to openly insult and belittle his enemies, notably disparaging their insignificant strength before his vampiric or Stand powers. He is the type who would be comfortable being with a man or woman; however, he will do anything to get what he wants and would "absolutely never pour 100% of his love into a specific person." Dio approaches obstacles and problems in a number of ways depending on the situation and his mood. When he was human, Dio was careful and methodical in trying to break Jonathan's spirit and slowly poisoned George for a sizeable period of time, only being thwarted due to unlucky twists of fate. As a vampire, DIO at first let his arrogance get the better of him and took a laissez-faire approach, only sending subordinates to kill the Joestar Group while he rested and recovered. However, his defeat by Jonathan taught him to be wary of the Joestar Family in its entirety, thus he would later ambush Jonathan. During the events of Stardust Crusaders, he would send his minions to delay the Joestars as much as possible to recover strength. During his final battle, his wariness, tactical acumen and arrogance would clash to make Dio alternate between meticulous approach and overconfident attacks.
