"The Flash" is still stacking the deck when it comes to speedsters. In addition to Barry Allen, the show has introduced Jay Garrick, Wally West, Reverse Flash, Zoom and Jesse Quick in its two seasons and, according to TV Line, they're looking to add one more.

The site reports that "The Flash" will introduce Eliza Harmon in episode 16 of the show's second season, which will air after the show returns from its winter hiatus in January. The character is described as an "exceptionally bright scientist" with a "split personality a la Jekyll and Hyde."

7 More Speedsters "The Flash" Should Let Run Wild

The comic book version of Eliza Harmon had a short lifespan, debuting and dying in the weekly "52" series in 2006. Harmon obtained her speed powers as part of Lex Luthor's Everyman Project, although considering that Luthor has yet to make an appearance on "Arrow" or "Flash," it's likely that the "Flash" version of the character will gain her powers through other means (Velocity 6, perhaps?) if she gains powers at all.

"The Flash" returns from its midseason hiatus on Tuesday, January 19th on the CW.
