Chaos is coming to National City when Supergirl returns next year as TV Line has confirmed that two fan-favourite villains will be making their return to The CW series. First up is Metallo (Frederick Schmidt), a Kryptonite powered baddie who squared off with both Kara Danvers and her cousin Superman in the two-part season premiere at the behest of the villainous organisation Cadmus.
Another familiar face also set to return is Brit Morgan's Livewire. The character targeted Cat Danvers during the show's first season, but later returned to take on both the Girl of Steel and The Flash alongside Silver Banshee. Story details have not been revealed about why these villains resurface, but seeing as Supergirl has struggled in this area, fleshing out some familiar faces is a really good idea.
Executive producer Ali Adler also tells the site that other "fan-favourite" villains will reappear this season, but wouldn't say any more than that. Who would you like to see the hero take on next?
