Grant Williams is embracing the Halloween spirit.

The Boston Celtics arrived to TD Garden for Sunday night's game against the Washington Wizards wearing a full Batman costume.

Check out the scene in the video below:

Williams' nickname is "Batman", although it's a self-proclaimed nickname.

You might remember this nickname was a storyline last season, especially when Williams played well. In fairness to Williams, he did look like Batman at times in 2021-22, including the Game 7 win over the Milwaukee Bucks in the second round of the playoffs.

Williams will make his return to the Celtics lineup Sunday after he missed Friday night's loss to the Cleveland Cavaliers due to a one-game suspension.

The Celtics will need a Batman-like performance from Williams to get back on track and avoid a third consecutive loss.
