8 Superman Supporting Characters That We Need To See In His Next Movie

2) Supergirl

A prequel comic for Man of Steel revealed that Supergirl actually arrived on Earth thousands of years before Superman in that crashed ship he discovered, which massively complicates her introduction in a future movie (though there are those who believe she may have ties to Wonder Woman).

The studio is unlikely to be beholden to a piece of barely seen tie-in material like that, so they could very well find a way of bringing Supergirl into this world, especially as she too would be a prime candidate for that rumoured Teen Titans spinoff.

There’s obviously a great TV Supergirl currently around in the form of Melissa Benoist, but if there’s going to be two versons of The Flash, there can surely be two Supergirls, right?
