X-Men and the Micronauts complete mini-series (issues #1-4). When a super-powerful, planet-destroying entity invades the subatomic microverse, the heroic Micronauts ally themselves with the tyranical Baron Karza to battle this mutual threat. Karza tracks the source of the Entity to the macroverse (our universe), discovering it has some connection to Prof. Xavier. The Micronauts are captured, so the X-Men shrink down and go to rescue them, but are also captured and subjected to brainwashing by the Entity. Meanwhile, Xavier struggles against the Entity on the astral plane. Eventually, the battle brings both teams back to earth. Oh, yeah, and the New Mutants also get in on the action. All comics are in good condition and are individually bagged and boarded.
