10+ Arrowverse Actors Are Returning for The Flash's 9th & Final Season

The Flash’s Tom Cavanagh as Eobard Thawne/Reverse-Flash

Tom returns one more time in the series finale.

“This is Barry Allen’s final race, so you can’t tell that story without including his most infamous adversary: The Reverse-Flash,” showrunner Eric Wallace told EW. “And having brilliantly played the character since season 1, bringing Tom back as our show concludes its run was always part of the plan. Tom‘s exciting portrayal of Eobard Thawne has been unforgettable for nine years, and fans will be delighted to know that he’s brought that same wonderful intensity to our finale, too.”
