We may have out first at Ant-Man's similarly powered nemesis in his supervillain get-up. Locate a grain of salt, of course, but this appears to be concept art of Yellowjacket, the outfit/armor worn by Darren Cross, the Ant-Man antagonist played by Corey Stoll.
Well, he's definitely rocking the black and yellow color scheme, but the extra arms are new. Also, is that an actual cloud of yellowjackets behind him, or are they Pym particles of some kind, like an effect that will occur when he and Ant-Man are shrinking or growing? Hmm. Well, either way I dig it. Thoughts?
