I'm thinking of........?

hello good people

I have two killing floor guest passes and rather than just throw them out to the first two comments I'm gonna make you work just a little bit

first one:
using what my avatar is from - tell me the name of the girl I'm thinking of that was in the magazine but NOT in the movie (because she showed up in millions of fantasies and started breaking hearts about 4 years after the movie was released
if you're at all familiar with Heavy Metal, yes it's who you should have immediately thought of
if you're not familiar, she was trapped in a nightmarish city that was actually a gigantic spaceship
oh, and please spell her name correctly because there is no Truth in spelling it wrong

DONE - thinking of Druuna

ok - 2nd pass:
I'm thinking of something - it's BIG, there are others that are bigger, but very few as legendary
it's not used for what it was built for anymore but it IS still used and when I win the lottery I am going to Germany and using it with SOMETHING - I don't much care what but I want to be there...
on a bad day in 1976 it led to someone being known as "The Phoenix"

adding hint
guess there're no race fans here right now - woulda got this instantly...
one that is nowhere near as big but arguably just as or more legendary depending on who yer talkin' to is being used today

DONE - two people answered the first part so they both get a pass...
