Rasputia is mean, selfish, cold, heartless, greedy, arrogant, deceitful, stubborn, lazy, disrespectful, and overall evil in nature.
Rasputia has a power-hungry demeanor as she had originally picked Norbit for a victim as a child and has since been controlling in every aspect of his life.
She is cunning and manipulative as she was the one who came up with the idea to turn the orphanage into a strip club and had her brothers Big Black Jack, Blue, and Earl (whom she also likes to control) carry it out.
Rasputia is a jealous person, evidenced when she saw Norbit with Kate. Later, when Blue was forced by Rasputia to tell her of Norbit's whereabouts, she lost her temper and immediately went driving around town to look for him and ultimately passed out when she witnessed Norbit and Kate kissing in church. After waking up and breaking out of her car, she grabs a crowbar and runs into the church in an attempt to kill Norbit, only to be foiled when she finds the church empty. This also shows her hypocrisy since she cheated on Norbit with her dance teacher, despite denying that anything happened.
Rasputia has a monstrous side as she even went as far as to maim Lloyd with her car simply because he was staring at her.
Ever since Kate came into Norbit's life, Rasputia has become more domineering and careless.
At the end of the film, Rasputia's rage and madness gets the best of her when she fights her way though the crowd at the church with a spade and tries to kill Norbit with it for foiling her plan, only to be defeated when Mr. Wong spears her with a curtain rod, making her drop the spade and run away.
Despite all of that, she shows to be devoted to her religion, believing in God and the afterlife. This is shown when she tries to indirectly offend Kate because of her slender appearance and says to her not blame God for her body shape when the latter said everyone is perfect the way God made them. Another example is when she accidentally cursed in the church when she found it empty in her failed attempt to kill Norbit and starts to pray like a way to ask for forgiveness. However, despite her claims to be a Christian, she violates every rule in the Bible.
- Her name is a play on Rasputin.
