Warner Bros. is certainly not holding back in building its expensive and ever-expanding roster of MultiVersus with original and well-known voice actors. It seems the company is also looking to invest heavily in future characters.
With Kevin Conroy voicing Batman and Tara Strong voicing Harley Quinn, it seems Mark Hamill is looking to join the MultiVersus roster as the Joker. It is only fitting to have Batman's "favorite" villain in the game too.
A data miner on Twitter, Laisul, recently shared some voice lines for an upcoming announcer pack. The voice appears to be the classic Joker's voice by Mark Hamill.
Laisul confirmed that the voice belongs to the new DC Joker character in the game. However, he cannot confirm whether Mark Hamill voices the character or not. But from what we've heard so far, it is certainly a possibility.
It is also interesting to see the Joker announcer lines getting leaked, as thus far, we only have announcer voice lines for characters that are playable in-game. This hints that Joker may be joining the MultiVersus universe soon, with Mark Hamil reprising his role as the Joker.
