We broke the news that 'Arrow' season 2 had tapped 'Percy Jackson' and 'Dawson's Creek' star Dylan Neal to play the villainous Dr. Anthony Ivo in a pivotal new arc for the DC drama, but how would you like to see the comic character in action? Watch Anthony Ivo make his 'Arrow' debut in the first clip from this week's DC showstopper "League of Assassins"!

Taking place in flashback, our first sneak peek of 'Arrow''s "League of Assassins" picks up where the pilot left off in showing Sara Lance (Caity Loitz) rescued from her apparent fate aboard the Queen's Gambit, only to be brought aboard the mysterious "Amazo" freighter on which Oliver would later encounter her. When Sara first arrives, however, the unnerving Dr. Anthony Ivo greets her and quickly justifies his work keeping several prisoners in adjacent cells as subjects, noting that his work will "save the human race!"

Our casting breakdown of the character revealed that Neal's Ivo would appear in a four-episode arc as a brutal but ruthless scientist who will stop at nothing to unearth a breakthrough that dates back to the latter days of World War II, likely something to do with those skeletons found in a cave in an earlier season 2 episode. The character also has the potential to recur beyond the initial four-episode commitment.

Meanwhile, here’s what The CW had to say on Wednesday’s “League of Assassins”:

THE CANARY SINGS — While Oliver (Stephen Amell) tends to the Canary’s (Caity Lotz) wounds, he tries to get her to talk about where she came from but she refuses.  However, after Oliver and the Canary are attacked at the Queen mansion by a trained killer from the League of Assassins, she confesses to how she’s connected with the nefarious group.

Meanwhile with Moira (Susanna Thompson) facing multiple counts of murder and conspiracy for her part in the destruction of The Glades, the Assistant District Attorney (guest star Dylan Bruce) offers her a choice – plead guilty now and avoid the death penalty or take your chances in court.  Thea (Willa Holland) begs her mother to fight for her life but Moira seems resolute about taking the offer.  Meanwhile, Oliver is furious with Laurel (Katie Cassidy) for joining the prosecution’s team on his mother’s case.

We're excited to see what other DC mythology crops up during "League of Assassins," but in the meantime, check out the clip of Dr. Anthony Ivo's 'Arrow' season 2 debut above, and tell us in the comments what you want to see from the CW drama's second season!
