A superhero show is only as good as its villains. With that in mind CBS has cast Chris Browning from Sons of Anarchy and The 100 as Ben Krull / Reactron. The character, created by Paul Kupperberg and Carmine Infantino, wears an armored suit powered by nuclear energy. In the comics he also has a heart of gold Kryptonite that allows him to de-power a Kryptonian for 15 seconds.
Browning will first appear in the third episode of the new Supergirl series that stars Melissa Benoist as Kara Zor-El.
