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.
In doing so, he becomes the most powerful foe the team has faced yet: Bloodwork.
Yes, a monster is coming to The Flash, and we're living for it.
The trailer showed off this new villain in action, and how he plans to get revenge on the people who don't believe in what he does.
In all honesty, he looks like the best bad guy the characters have faced yet.
There's something scary about dealing with someone who quite literally transforms into a monster.
