Calculator Takes on Overwatch and Roy Harper Returns in New 'Arrow' Preview
The Calculator will wreak havoc in Star City despite the lame name. "This what happens when bad guys name themselves," Felicity says in the new trailer. She'll have to match wits with the newest baddie under her new codename Overwatch. Roy Harper (Colton Haynes) also returns but he's not in the 'Arrow' video promo unfortunately.
"Arrow" airs on Wednesdays on the CW.
