Listed on otakumode.com for pre-orders now is the DXF ONE PUNCH MAN SAITAMA Figure from Crane King / Banpresto, with this 19cm / 7.5" tall pre-painted, articulated, non-scale ABS & PVC figure priced at US$38.00 apiece. Do check in with your fav retailer(s) for availability as well. Release is in October 2016.
This version sees "Saitama" in his "heroic human" guise, with none of the manga-ish simple ball-headedness in sight! Oh man, I can only imagine if there ever will be a "GENOS" version!
