Barry Allen and his inner circle have a whole new villain to take care of on The Flash Season 6.
The first trailer for the upcoming season dropped during the show's San Diego Comic-Con panel on Saturday, and it looks wild.
Heroes alum Sendhil Ramamurthy is joining The CW drama as Dr. Ramsey Rosso, a face from Caitlin's past.
He's the world's leading expert on hematological oncology, so he's a pretty big deal.
The pair are reunited under the strangest of circumstances, but their friendship is quickly put on thin ice when Ramsey travels a dark past.
