Collects X-Men (2021) #19-24. Lord of the Brood! When the X-Men get a distress call from deep space, they find that the galaxy's Brood problem is not as solved as they'd thought! Rogue Brood factions are running wild, and now it's up to the X-Men to get to the bottom of why! Back when their ally Broo became the Brood King, he gained the ability to control the savage alien race. Now he's experiencing his own nightmare scenario: The Brood are killing his friends, and there's nothing he can do to stop it! Meanwhile, Orchis' plans are in motion, preparing for the fall, and the anti-mutant fantasist called Feilong has taken control of Tony Stark's businesses - and turned Iron Man's technology toward creating the next generation of Sentinels! All this, plus the glorious return of Pogg Ur-Pogg!
