Who is this X-men character?

That's Archangel (Warren Worthington, III) in his "X-Force" uniform. These days, he can transform back and forth between his "Angel" persona (white skin, feathered wings) and the "Archangel" persona (blue skin, techno-organic metal wings). I think what might have caused your confusion is how the artist rendered the wings. It looks like he downplayed their appearance so that they wouldn't block the images of Fantomex and Deadpool (who are also members of the current X-Force roster).
