On Tuesday, we gave you the name. Metal. For DC's big new Batman-centric event for the summer of 2017. From Scott Snyder and Greg Capullo.

But what does it mean?

Well, we have been tipped off that it concerns the concept of Nth metal.

In the DC Universe, Nth metal is native to Thanagar, home planet of the Hawkmen, and allows its residents to negate gravity and fly, while also protecting them from temperature, the elements, increasing their healing factor and granting extra strength.

Which, I have to say, may be rather tempting to Batman. A belt made of Nth metal? And entire suit? What about Batarangs?

But someone else has their eye on the properties of this metal and is trying to gather it up.

Can we expect a metallic foil cover for the book – andy any spinoff titles? Probably.
