EDIT, December 8 at 5 p.m. ET: This image is, indeed, a hoax. We apologize for our error and will have more details soon.
A new Warner TV Asia promo for this week's midseason finale for Arrow, unearthed by SpoilerTV, has revealed the first look at Brandon Routh's A.T.O.M. exosuit in its complete form.
EDIT: Yes, it does look suspiciously similar to a costume used in the Fallout video game franchise. Since these kinds of ads pop up in international markets all the time and are almost never "faked" in poor quality, it seems likely this is genuine and that hopefully the costume will be different when the show airs. We've inquired about the authenticity just to be safe and will update the story if we get a response.
If you look closely, it does still appear to be a 3-D hologram, like the last time it appeared on the series, but this time it's not only much more complete, but Ray Palmer expresses to Felicity that it's created for the purpose of protecting Starling, establishing the likelihood of The Atom as a vigilante like Arrow or The Flash.
This is the second time in two weeks that a major member of the Justice League has debuted on The CW, with fans getting their first look at a powered-up Firestorm last week on The Flash. Firestorm will play a bigger role on the series going forward.
You can check out the full video -- which has what appears to be a pretty decent spoiler -- below.
Arrow airs Wednesdays at 8 p.m. ET/PT on The CW. The midseason finale will air this week, so watch out for an interview with executive producer Marc Guggenheim on ComicBook.com soon!
