Elon Musk's biography, titled "Elon Musk," was recently published, and it contains some unusual stories about the Tesla CEO. Written by biographer Walter Isaacson, the book delves into Musk's life, including some peculiar incidents.

One of the book's revelations is that Musk once asked his former girlfriend, Amber Heard, to dress up as a video game character. Additionally, it claims that Musk sent pictures of Grimes having a C-section during the birth of their first child to members of her family, causing her distress.

The biography also introduces Musk and Grimes' third child, named Techno Mechanicus (nicknamed 'Tau'), who joins their siblings X Æ A-12 and Exa Dark Sideræl.

Furthermore, the book sheds light on Musk's past relationship with Amber Heard, which took place between 2017 and 2018.

According to Isaacson's biography, Musk's family strongly disliked Heard, leading to a tumultuous relationship that Musk described as 'hellacious.'

The biography has more to say about Musk and Heard's relationship, and Musk himself seemed to confirm one of the claims on his social media platform.

According to the biography, while they were together, Musk asked Heard to dress up as a video game character named Mercy from Overwatch. He even posted a picture as evidence of this request.

The reason behind this unusual request, as mentioned in the biography, was that Musk saw a resemblance between Heard and the character Mercy.

For those familiar with Overwatch, Mercy is a popular character known for her strong healing abilities, making her a valuable asset to her team.

Even if you haven't played the game, you might recognize her from the memes where an angelic figure extends a helping hand to someone in distress amidst rubble.

Musk's biographer revealed that there were times when the CEO would enter a state he called 'demon mode.' During these moments, Musk could become rather unpleasant and show a lack of empathy, especially towards those who didn't share his intense focus on a task.

Interestingly, the term 'demon mode' was actually coined by Grimes, Musk's partner, to describe the determined and intense moods he would slip into when he was determined to accomplish something.

Additionally, Musk expressed feeling 'pained' by his daughter's decision to sever ties with him and relinquish the family name. The biography also touched on the topic of Musk's supposed plans to engage in a fight with Mark Zuckerberg, shedding some light on this unusual idea.
