Arrow has cast its villain for its season 4 flashbacks.

British actor Jimmy Akingbola will play Baron Reiter, who is better known in DC comics lore as Baron Blitzkrieg; the role will be recurring and be featured in the flashbacks that take place prior to Oliver being rescued from Lian Yu and returning to Starling City.

At the end of season 3’s flashbacks, Oliver left Hong Kong after parting ways with Tatsu Yamashiro; Tatsu went into a life of solitude after the death of her son, Akio, and being abandoned by her husband, Maseo. Maseo would go on to join the League of Assassins.

Notably, in the DC comics, Baron Reiter is the leader of a group known as Shadowspire and — relevant to Legends of Tomorrow — allied with Vandal Savage’s organization, Symbolix. Shadowspire’s M.O. involved supplying South American drug cartels with weapons, transportation, and intelligence.

Arrow will be Akingbola’s second role in America; he first appeared in Sons of Liberty. His other credits include Ballot Monkeys, Rev., Holby City and Holby Blue.

Akingbola joins several recent additions to Arrow‘s fourth season, including Neal McDonough as Damien Darhk, Echo Kellum as Mister Terrific and Alexander Calvert as Anarky.

Arrow‘s fourth season is being billed as lighter and more “Green Arrow-y.” Oliver will be getting a new suit more similar to his comic book counterpart, though “the show isn’t going to suddenly to become a comedy,” EP Andrew Kreisberg said at Comic-Con.

“When the season starts, [Oliver’s] in much a better place. He’s happy. He’s in love. That feeling infuses all the characters. There’s a little bit more fun [and] more humor.”

Arrow season 4 premieres Wednesday, October 7 at 8:00 p.m. ET on The CW.
