Ray Palmer's been tinkering on his suit for The Atom for awhile on Arrow now, but the time has come for him to actually don the costume of the DC superhero.

The CW and Warner Bros. have just debuted the first image of Ray (Brandon Routh) in the Atom costume, which you can see below.For now, Ray's costume is a suit of armor - that, as far as we know, doesn't allow him to change sizes, like in the comics. Will that change? We'll see, as we do know Ray and Felicity Smoak will pay a visit to The Flash this season, where Ray gets some assistance on the suit - which likely means we'll see The Atom in costume teaming with The Flash, given the episode is called "All-Star Team-Up."

We'll see Ray Palmer first don his Atom costume in the 15th episode of Arrow: Season 3, airing February 25th on the CW.
