It seems like the Halloween fever has already caught up to Grant Williams. The Boston Celtics faced the Washington Wizards on October 30, 2022, at the TD Garden. This was the Celtics’ sixth game of the regular season and Jayson Tatum and co. grabbed their fourth victory on Sunday night. However, Williams managed to become the highlight of the evening when he arrived to the game wearing a Batman costume.

Grant Williams had earlier given himself the nickname ‘Batman’ after the Boston Celtics vs Denver Nuggets game on March 20, 2022. Williams decided to adopt the nickname after his splendid defensive performance against Nuggets’ Nikola Jokic, who is known as the ‘Joker’. Williams actually asked teammate Jaylen Brown to spread the word through the media.

“Grant did a great job. He wanted me to tell the media he wants his nickname to be Batman. I said, ‘I don?t know about that one Grant.'” said Brown.
