VENUS and Serena Williams' father was accused of being "erratic" and owning an "arsenal including an AK-47" by his third wife, unearthed documents show.
The estranged wife of Richard Williams - the subject of the new biopic King Richard - sensationally claimed in divorce papers that he "acted hostile" during their marriage and she feared he'd harm their young son.
Former tennis coach Williams, who is portrayed by Will Smith in the new Hollywood hit movie, filed for divorce from his third wife, Lakeisha Graham, back in 2017 after seven years together - but the pair are still going through the courts.
In a series of bombshell court documents, she alleged she had to remove an "arsenal of firearms including an AK-47" from their home and claimed she was forced to raise their son Dylan alone as he "refused to get involved", reported.
Amid their messy divorce, Lakeisha, 42, also claimed Williams, 79, used to drive through poor neighborhoods looking at women.
In her 2019 deposition testimony, she said: "He did likes to drive, you know, and not stating anything. He likes to go through poor neighborhoods.
"He likes to take me like Downtown Los Angeles. He always liked to take me to neighborhoods where, you know, there was Black women, because he likes women. Yes, so to speak."
But Williams hit back with his own allegation in the bitter battle, claiming Lakeisha forged his signature to transfer their West Palm Beach property into her name.

Lakeisha admitted imitating his writing, but said in court documents he asked her to do everything for him due to ill health, and the deeds and mortgage were all notarized and witnessed at a loan company.
It comes after Serena and Venus' half-sister Sabrina Williams accused her father of not paying her mother child support, leaving her and her siblings to grow up in poverty.
Speaking to The Sun, Sabrina said Richard's desertion when she was just eight years old hit the family very hard.
She accused her father of walking out after telling her he was going out to buy her a bike and never returning.
That left wife Betty - Sabrina's mom - to raise their six children alone.
"I had two childhoods, the childhood from one to eight was fantastic," Sabrina recalled.
"But once he left, within a year, we became very poor. There wasn’t always meals on the table. We went downhill."
The new movie King Richard shows how a man with no background in tennis and very limited financial resources guided his daughters to unprecedented success.
It reveals the racism, violence, and hardship the Williams family had to overcome.
And it details just how "complicated" a man the three times married Richard is, according to Oscar-nominated actor Will Smith.
