You've heard of Superman, Spiderman and Batman... but now there's a new superhero in town.
The costume is now available to buy in Club stores and Shearer's Bar, priced at £49.99.
Ideal for nights out and stag dos, it will also make an eye-catching outfit for home and away games.
It is part of the Club's new range of fancy dress wear, for men and women which include the NUFC Second Skin and the NUFC Toon Tottie garments.
And to celebrate the launch of Whey Aye Man, nufc.co.uk is inviting fans to send in photos of where they spot the superhero over the coming weeks.
Nobody knows who he (or she) is but if you spot Whey Aye Man out and about, email your snaps to firstname.lastname@example.org and we'll publish the best ones.
