Supreme 4 was published in Jul 1993 with a plot by Rob Liefeld; pencils, script and colors by Brian Murray; and lettering by Kurt Hathaway.
After dealing with the terrorists at Dulles Airport in Washington, DC, he flies off to go confront Khrome, the alien leader with a grievance against Supreme.
We get some scenes of infighting with Heavy Mettle, but they're not going to be around much longer, so let's not worry about them.
As Supreme fights a Khrome clone, the real Khrome transports to Dulles and blows it up, for reasons that are never explained. I think to punish Supreme?
There's a long pointless fight between Khrome and Heavy Mettle, which goes about how you would expect.
Supreme figures out the clone situation and goes down to fight Khrome.
We don't really learn anything new about Supreme or anything that will become important in his later, Moore incarnation.
This is kind of what I assumed these early Supremes were like and they're not letting me down!
Next time... more Khrome... yay.
