I doubt many are aware that the debut of the Justice League in the DCAU was in Batman Beyond. It was called the JLU, but it was different than both the regular Justice League Unlimited and The Legion of Super Heroes from the future. It appears in the impressive two-parter, The Call. HBO Max is the only official place to view it as far as I know.Finished The New Batman Adventures. Have just begun its successor, Batman Beyond. In the past, I was turned off by the unique costume and the fact this Batman is not Bruce Wayne. But I have since developed a more expansive attitude. I now appreciate the logic of depicting Batman once Bruce Wayne had become too old. Probably also watching several Robins come and go softened me up as well.
So far, it looks good. And I'm looking forward to seeing the bat-tech of the future.
