No Max Mercury? or Impulse? Maybe next year.............Come to think of it - DC had an awful lot of speedsters. Marvel had Quicksilver and Mongoose and.............that's all I can think of.
Plus I would die happy if they did an Earth 3 - where Barry and Arrow are the bad guys and people like Heatwave and Captain Cold and Mirror Master are the good guys.
Mirror Master hasn't shown up on the show yet, has he? Or am I just not remembering...
But, yeah, I hope they go there, sooner rather than later. And let's not get into the whole Impulse/Barry's Grandson thing yet.
I am wondering if they're gonna give Jesse Quick the backsotory of being the daughter of two older meta-humans who inherited their combined powers, like in the comics. That would be a good way to acknowledge, and introduce into the show, that in the DC-TV Universe there was a previous generation of superheroes.
Now that they're introducing multiple universes, maybe we'll get a crossover with the DC-Movie Universe, or the DC TV Cartoon universe... LOL... One can dream...
