Notice, Kevin Conroy, the voice of Batman, died on November 10, 2022, the day leaving 51 days in the year. Of course, ‘Batman’ equates to 51. The date can also be written 10/11, a lot like 111.
Batman = 51 / 111

And as for dying at age 66…
Batman Voice = 66
Number of the Beast = 66
–Batman = 666

RIP.

Update: New York City (Gotham City) lit up the Empire State Building in tribute to Kevin Conroy on November 11, 2022, the ‘kill date.’

Remember, Batman’s ancestor created Skull and Bones at GOTHIC Yale.
