I’m currently watching The New Batman Adventures animated series and the thing that I don't understand is why Livewire (aka Electro Girl) suddenly appeared in the series. She is supposed to be from Superman universe. Then out of the blue Supergirl came too.
I understand that at that time both Batman and Superman were two mainstream superheroes and new episodes were released of both shows. But still, why were they interconnected?
I understand that this is the same DC Universe and that it is physically possible (since Gotham and Metropolis are adjacent cities near NY) for them to meet, but it kind of irritates me.
I kind of believe it was done for the comparison of the characters. But what to compare? Super powers vs no super powers? Weird.
P.S. I sincerely believe that The New Batman Adventures are tacky (not sure about Batman Beyond)
