I never read much! The original stuff I mean – Deaths Head, Knights of Pendragon, etc. I had access to US imports, and I had 2000AD, and the Marvel UK stuff just seemed… obviously lame, in that instant-judgement teenage sense. They were on different paper, they LOOKED wrong, they were the Cliff to Marvel US’ Elvis. And then I was a smidgen too young for the earlier wave of Marvel UK stuff with Night Raven and Captain Britain.
So my Marvel UK was primarily a reprint house. So this top 5 is a mix of things that originated there and things that I first read through the reprints there.
1. Secret Wars: stretched out over 30 or so fortnightly issues. Introduced me to every Marvel character basically. Amazing. Terrible. Amazing.
2. “THE BLACK ZOID” early super derivative Wagnerian toy fight epic by Grant Morrison. The only original material here.
3. John Byrne FF vs Psycho Man and Hate Monger: after Secret Wars they reprinted Secret Wars II, which necessitated reprinting not only the mini but the crossovers and EVERY surrounding issue that resolved subplots raised in said crossovers. Ridiculous. But it meant we got all of John Byrne’s fevered, kinda queasy with hindsight but uh ‘resonant’ bondage epic ft dominatrix Sue Storm. (It’s the enslaved She Hulk sequences I think would read unpleasantly now tho)
4. Strikeforce: Morituri – Peter Gillis’ fantastic doomed kid super-soldiers series, no idea why they reprinted it.
5. Iceman – JM DeMatteis’ weirdo Iceman mini in which he confronts (this being JM deM) questions of death and reincarnation. Absurd but memorable clash of hero and storyline, has surely never been mentioned since.
It’s scary how much this mirrors my own Marvel UK experience.
The Iceman mini was reprinted (in a hardcover, because Marvel) a few years back, and it has to be said: half-remembered nostalgia was far kinder to that than revisiting the actual thing.
