Okay, let's pause from reading the regular issues for the Supreme: Glory Days miniseries. It was only two issues and looked at Supreme's WWII-era activities.
Issue 1 came out in October 1994. The story was by Rob Liefeld. Written, edited and lettered by Kurt Hathaway. Pencils by David Williams and inked by Gary Martin. Maybe this is the Volume I that they were talking about?
We start the series in the waning days of World War II, as Hitler has just committed suicide. We then see Supreme as part of the Allied fighting forces. It's basically an excuse for Williams to draw Supreme fighting Nazi images, and to be fair, they look great.
An allied soldier asks Supreme to go check out a mysterious bunker, which Supreme happily does. It's weird. This doesn't feel like the Supreme we know from the main series. No moody, surly, Supreme this guy. This is much more of a Captain America, gung-ho mentality about him.
At the bunker, Supreme finds The Baron, a Nazi mad scientist, who has made a giant fighting robot called Die Maschine, which Supreme takes out with one punch.
We cut to the White House where Supreme is telling President Truman, Glory and Die Hard that he is planning on leaving the planet because he believes he has a higher calling.
Glory tries to stop him, but he says that he would ask her to go with him, but he thinks he would know what the answer would be. I guess this is as close to the Supreme we know, doing what he wants and not really caring what anyone else wants.
We then cut to decades later when Supreme has returned from outer space. In Manhattan, we see Glory on the phone, turning down an endorsement deal for makeup since she doesn't have to wear any. That's when Supreme shows up and calls on his "Honey." Glory's not having that and decks him.
Meanwhile, In German, some neo-Nazis are searching for the body of The Baron.
Supreme and Glory talk some. Glory wants to know if Supreme is back for good, but he can't promise that he is. So she flies off.
Meanwhile, the remains of The Baron are brought to Project Born Again to be... you guessed it... born again.
It's a pretty enough book but not a lot happens. We'll have to find out if anything of substance happens in part 2.
