Superhero show "The Flash" is getting a dose of magic for season three: "Harry Potter" alum Tom Felton is joining the series.

TVLine reports that Felton will be a series regular when the show returns this fall, playing a character named Julian Dorn. The site describes Dorn as "a fellow CSI at the Central City Police Department who suspects there's more to Barry Allen than just his good guy reputation."

That description certainly sounds familiar to those who already know Felton well from his "Harry Potter" days, when he played Slytherin student (and eventual Voldemort sympathizer) Draco Malfoy. At first, the thirsty-for-pureblood-pals Draco tries to befriend Harry, only to quickly sour on The Boy Who Lived, and make Harry's life a living hell at every turn.

The addition of Felton isn't the only exciting thing awaiting "Flash" fans this fall: The series also plans to introduce the famous "Flashpoint" storyline from the comics (which TVLine explains here), beginning with the season premiere.

There's no word yet on exactly when Felton/Dorn will make his debut, or how long his arc will last, though TVLine says he's expected to show up sometime "early during Season 3."

"The Flash" returns to The CW on October 4.
