“The Flash” executive producers Todd and Aaron Helbing have revealed a number of news details about the two main villains that Barry (Grant Gustin) is going to face in Season 3.

As previously reported, the CW series will introduce Dr. Alchemy and the speedster Savitar as the big baddies of the upcoming installment, and although the two characters couldn’t be more different from one another, Todd teased that their individual agendas are somehow similar to one another.

When asked if the two villains are going to be working in concert, Todd told IGN: “I'll just say that Dr. Alchemy's plan and Savitar's plan are not much different.” While he wouldn’t disclose what those plans are, he did assure fans that Savitar is not like the show’s previous speedster villains Reverse-Flash and Zoom.

“Savitar is more of a psychological villain in a weird way,” Todd shared. “I think the Hindu word for Savitar means God of Speed; he's all about speed. Everything about this guy is different. I can't go into super detail, but he's not like Zoom or Reverse Flash.

Dr. Alchemy, on the other hand, as his name says, is an alchemist. “He can take X and turn it into Y,” Aaron told Collider. “That mirrors what happened with Barry when Barry was just this normal CSI who was happy go lucky, and then he got struck by lightning with the dark matter from the Particle Accelerator. That was almost a form of alchemy, where it changed him into The Flash. We can really explore alchemy, in that manner of being able to take X and turn it into Y, and see how that mirrors what actually happened to The Flash and all of the meta-humans in Central City.”

Todd didn’t discuss much about Dr. Alchemy, but he told IGN that viewers are going to be shocked when they find out what the villain is up to. “I think when you find out what Alchemy is doing, it sort of provides that ‘holy s--t’ moment that we really love to have on our show.”
