If there was any doubt that the minds behind The CW’s Arrow and The Flash were looking to Roman-era action/drama for their casting, the latest confirmation should put it to rest. With Barry Allen’s path to superheroism looking to get even more challenging when the show returns from its winter hiatus, it seems fans can look forward to one more member of his classic Rogues Gallery being brought to life.

After some speculation online, it seems ComicBook.com has confirmed that Australian-born Liam McIntyre (Spartacus: War of the Damned) will be joining the show as villain Mark Mardon a.k.a. Weather Wizard. How another metahuman with control of the weather will pose a threat to Central City isn’t clear, but the seeds for the character’s addition go all the way back to The Flash‘s premiere episode.

For those watching the show from the start (and keeping track of the various villains’ comic book past) it was assumed that Weather Wizard had already gotten his moment to shine in the pilot. In the episode, mastery over wind and precipitation was granted to Clyde Mardon (played by Chad Rook), one half of the infamous ‘Mardon Brothers’; responsible for a number of armed robberies. But when the S.T.A.R. Labs disaster turned the pair’s plane to scrap metal, the other Mardon brother’s fate was never explained.

Presumably, until now (or, to be more exact, several weeks from the time of this writing).

In keeping with the comic source material, it will be Mark Mardon who fully adopts the mantle of Weather Wizard, apparently blessed with the exact same (or similar) powers of his now-deceased brother. With Detective Joe West (Jesse L. Martin) responsible for his brother’s death, it’s safe to assume that Barry’s adopted father will be his prime target. That means he’ll have Central City’s Flash to contend with (assuming Firestorm hasn’t emerged on the scene by that point as well).

However, the rest of the antagonists being recruited implies that McIntyre (only the latest Spartacus alum recruited to The CW’s shared universe) may make some powerful allies of his own. The second half of The Flash‘s first season already promises to bring more of the Rogues to the screen than fans likely hoped. Captain Cold (Wentworth Miller) and Heat Wave (Dominic Purcell) are set to join forces, Cold’s sister Golden Glider (Peyton List) isn’t far behind, and even Mark Hamill’s Trickster is getting a return appearance.

The only real risk facing the showrunners is keeping the Rogues, as a team and individually, compelling for the long run. Fans would have gotten on board with introducing even a single Rogue or two per season, so while cutting to the chase is sure to be well-received, it brings its own set of challenges.

Whatever the writers have planned, adding another popular actor among their target audience can’t hurt. It’s particularly good news for Spartacus fans, as McIntyre joins Arrow‘s Manu Bennet (Deathstroke), Cynthia Addai-Robinson (Amanda Waller), Nick Tarabay (Boomerang) and Katrina Law (Nyssa Rhatko) as former members of the Starz series.

The Flash airs Tuesdays @8pm on The CW.
