First, it was believed that Ray Palmer's A.T.O.M. suit made its debut in holographic form during an international teaser for "Arrow’s" mid-season finale. However, the armor in the promo was quickly debunked, with eagle-eyed viewers noting that it was actually the Chinese Stealth Armor from the video game "Fallout 3."
Finally, after all of that build up and mystery, the A.T.O.M. suit was truly unveiled during last night's jam-packed episode, "The Climb." In the installment, Brandon Routh's Ray Palmer fired up his equipment and shared his designs for the suit with Felicity Smoak, teasing the costume he will eventually don when he brings DC Comics' diminutive hero to life. And, judging by what Executive Producer Marc Guggenheim had to say when discussing the episode with CBR, the suit is just the tip of the iceberg when it comes to the "Arrow" crew’s plans for Palmer.
"We're going to see the ramifications of the kiss that Felicity and Ray had," Guggenheim told CBR. "We're going to learn a pretty significant piece of Ray's backstory. We're going to get a pretty nice glimpse of the super-suit he's been building."
Palmer calls it the Advanced Technology Operating Mechanism, designed to allow him to protect Starling City. But considering that the inspiration behind it's creation was to allow one man to have a plethora of military technology in the palm of their hand, the potential ramifications of Queen Technologies' initial designation for the suit -- O.M.A.C. -- indicates big, big trouble could be coming to the CW series when it returns for the back half of its third season. In the comics, O.M.A.C. initially stood for One Man Army Corps, which syncs up nicely with the suit's abilities. It later became the acronym for Omni Mind and Community, a cyborg technology with the remit to capture and/or kill those with metahuman abilities
"Arrow" is on winter hiatus and will return with new episodes on January 21, 2015.
