It certainly sounds that way and is very exciting if it is true! Blue Bettle: a superhero who uses tech to fight crime would fit right in with Ollie and his team of vigilantes.
Below is the report from superherohype.com with some more major character synopses:
TV Line has managed to get their hands on a number of character breakdowns for some new roles for the upcoming third season of “Arrow,” and it would appear we’re getting some new DC heroes added to the mix!
The first character is “Daniel,” a name the site says is likely a placeholder so as not to reveal the character. His breakdown reads: “20something gent — a major recurring character for Season 3 — is a handsome, enigmatic and highly intelligent entrepreneur developing groundbreaking technology. (Picture a business magnate in Ryan Gosling’s body.) Though exuding charm and confidence in public, he privately harbors a tragic past that will drive him to become a tech-powered superhero. Watch for this formidable fella to be a love interest for Felicity and a rival of Oliver’s – both personally and professionally.”
Given previous mentions of the character and his company in “Arrow,” and the “Tech-powered superhero” bit, we’re going to guess that this character is actually Ted Kord aka The Blue Beetle. A member of the Justice League in the comics, as the Blue Beetle Kord utilized a variety of gadgets and weapons to take down crime in addition to being a skilled acrobat and martial artist.
The second character description is for a character named “Seth” and it reads: “A well-educated criminal with grand ambitions and a knack for chemistry, this potentially recurring character gains power over his enemies by exposing them to a drug that drains their willpower. Oh, and he is very much a physical match for The Arrow.”
It’s possible that this could be Jonathan Crane aka Scarecrow, though he’s never been much of a physical match for anyone in previous incarnations.
The final two characters are potentially original ones, who will appear in the flashbacks of the new season, named “Toshi” and “Akiko.” Toshi is described as: “Oliver’s teacher and handler, and eventually a friend. A well-trained operative, skilled in weaponry, combat and intelligence gathering, he is also a devoted father and husband.”
While Akiko is described as: “Toshi’s wife is another of Oliver’s Hong Kong caretakers, and is herself highly skilled in martial arts.”
