Baron Karza is rebuilt and the ‘Nauts are fighting him, blah blah. The main point of these issues is that SHIELD got a hold of a spaceship and some fallen Micronauts during their last trip to the 616.
Commander Rann, who has access to some new powers, watches as Earthlings begin to explore the mystery of the Micronauts.
This leads to a battle against Psycho Man and a trip by the Fantastic Four into the Microverse, where they meet the ‘Nauts on their home turf.
Howard Chaykin is the new artist for several of these issues. He gets a nice feature on the letters page.
