The Hollow is a bladed weapon wielded by Xero. It made its debut in the first issue of Xionic Madness.


An unusually long bladed Ninjato, this weapon is made with a special compound that allows it to avoid light reflection, thus rendering itself invisible to human vision.

It was a payment from a Japanese client after the Bolverk Squad performed a mission for him. It's uncommon length allows the user to execute mortal blows and with certain advantage, although extensive training is required to get used to the blade's reach.
