The CW has been building up its shared DC TV universe over the past few years, first introducing Barry Allen (Grant Gustin) on Arrow before he became The Flash on his own television series. This season, both Arrow and The Flash have been battling their own major villains - Damien Darhk and Zoom, respectively - while also setting up the third DC TV series set to premiere on The CW: Legends of Tomorrow.
Arrow, for its part, has been utilizing smaller DC Comics villains within its fourth season to act as one-off antagonists in certain episodes this year. Already, Anarky (Alexander Calvert) and Double Down (JR Bourne) have appeared in episodes in Arrow season 4. Now another lesser known DC villain will appear later on this season in a two-episode arc.
Early versions of Calculator in the comics had the villain using a suit containing computers that could analyze and predict the actions of any hero he faced in order to defeat his opponents. Later on, though, Calculator relied on his intelligence and skill in strategy to manipulate those around him. From the description of Amandes' take on the character, it would seem Arrow will feature a version of Calculator who uses his own abilities rather than a battlesuit in order to blackmail Roy.
This season of Arrow has seen less of a focus on one-off villains as Darhk and the Legends of Tomorrow have taken up the majority of storylines in season 4 - Team Arrow dealt with the resurrection of Sara Lance (Caity Lotz) as well as tracking down and re-enlarging Ray Palmer (Brandon Routh) who will go on to star in Legends. Although those one-off villains that have appeared, like Anarky and Double Down, were working for Darhk, it doesn't seem Calculator will tie into Arrow's major antagonist this season.
That being said, the Calculator arc will serve another purpose: bringing Roy back into the fold - even if only for a short while. However, since it seems Amandes will only appear in episodes 12 and 13 of Arrow, it's likely he'll be another one-off villain for Team Arrow to fight and defeat in a span of two 43-minute episodes. Though fans of the character from the DC Comics may be excited to see him brought to life on Arrow, the Calculator will likely take a back seat to the return of Roy Harper.
