Him

HIM is shown to be an extremely dark soul. He is bitter, evil, ruthless, mysterious, diabolical, domineering, and possesses seemingly no motive other than the personal sadistic pleasure of the suffering of others. He treats everyone as a plaything, an easily replaceable toy that can be controlled and broken to his heart's content. It is shown that HIM could destroy the world quite easily if he wanted to, though his insistence on playing mind games with the girls to make things entertaining for himself is always his downfall as he has a bad habit of underestimating the girls' willpower and overall resourcefulness as a unit. This is likely due to his inability to comprehend their sisterly bond and the internal strength that comes with it.

Unlike most villains, HIM learns from many of his mistakes as he mentioned himself. Pretty much everyone, even the villains in Townsville, are frightened of HIM, though it is shown he is on decent terms with some of them from time to time.

Despite his psychopathic nature, he generally carries himself with a very flamboyant demeanor, usually speaking in an echoing effeminate falsetto. However, when he becomes furious, his voice changes to become a deep, masculine, commanding, and demonic growl.

HIM is actually shown to be quite polite when not causing mayhem. When the Girls first confronted him in "Telephonies", HIM acted nonchalantly and non-violently until they left, though it was shown afterward that HIM was actually angry about the situation due to his rights as a citizen. He has also been shown to have fatherly pride in the Rowdyruff Boys, as seen in "Custody Battle", even shedding tears of joy when they made him proud. Whether this is actual love or simply immense satisfaction of his competent minions is unknown.
