David Meunier will appear as Bratva bigwig Ishmael Gregor and play a key role in the Season 5 flashbacks.
Season 5 is going to be a big year for Arrow as the show comes full circle on Oliver’s five years of hell.
Given that magic was a huge element in Arrow Season 4, it won’t come as a huge shock if the Arrow version of Gregor is curious about demons.
The character will recur throughout Season 5, so David Meunier should have an important part to play in Oliver’s ongoing journey through the ranks of the Bratva.
