At a panel for "The Flash" at San Diego's Comic-Con International, it was revealed that classic DC Comics villain -- and non-speedster -- Doctor Alchemy will be making his debut in the third season as a villain.
"We're doing two big bads. One is a speedster, and the other is Doctor Alchemy," "The Flash" producer Todd Helbing revealed at the panel.
In the comics, Doctor Alchemy is a scientist with multiple personality disorder who harnesses the ability of transmutation -- kind of like Firestorm -- using it to wreak havoc on humanity. He's made appearances on various DC Comics-based animated series, and most recently showed up in Geoff Johns, Doug Mahnke and Ivan Reis' "Justice League" #30.
There's no word yet on which episode we'll first see Doctor Alchemy.
"The Flash" returns Tuesday, October 13, at 8pm ET, on the CW.
