The big bad.

If you weren’t aware, James Patrick Stuart (ex-Will Cortandt) has been recurring on “Supernatural” as Dick Roman since October 2011. His next appearance will be on April 27.

Dick Roman, in human form, was a billionaire businessman and one of the most powerful men in America. He was taken over by the Leviathan leader and became even more powerful and ruthless.

In case you don’t know, Leviathans were among God’s earliest creations. However, the beasts became too destructive and were banished to Purgatory. On “Supernatural,” the Leviathans, many of whom take their orders from Dick Roman, hunt down others like them who feed indiscriminately. They must also deal with the Winchester brothers, played by Jared Padalecki (ex-Dean, “Gilmore Girls”) and Jensen Ackles (ex-Eric, “Days of our Lives”) who hunt demons and other supernatural figures.

Watch the promo of the April 27 episode titled “The Girl With the Dungeons and Dragons Tattoo.” In it, Dick Roman acquires a hard drive that contains sensitive information about the Winchesters and tasks a brilliant hacker with cracking it, but the brothers find out.
