Hey all:
With my childhood resurfacing, I remember watching an animated Batman drive a pink car in a desert when he got to a dimension where the earth was in the future. He finally found a city which Lex Luthor owns. Lex in all his glory has no one to share it with because he kills the whole league. Batman gets mad and punches him. Lex tells Batman go back in time and erase Lex from the timeline to get a normal progressing future beyond his.
What episode of Batman Beyond, Justice League/(unlimited) is this?
I would appreciate the share appreciation toward the animated Batman series.
