The Agents of G.A.T.E. vs. the Brothers of the Bomb! Beyond time, space, and reality, there lies the Unknown... and now it's coming here! When soldiers from a mysterious foreign realm arrive on Earth, it's up to the armored Visigoth known as X-O Manowar - newly returned to the planet and now the leader of his own elite G.A.T.E. unit - to deal with the intrusion. But are these otherworldly emissaries truly the threat they appear to be, or does a larger danger loom over the Valiant Universe still? Collecting X-O MANOWAR (2017) #19-22.
