Outer SPace Villain drains Human Fluid with HandGun

[Khan]

Hello everyone,
I am new here and I hope to contribute as best as I can to this
awesome forum/site which I have stumbled upon. I praise its
owner/creator Andrew, because for us, it might be a fun place to visit
but I sure understand the workload it must put on him to keep it
going. I live in Lisbon , Portugal.

That said, if anybody can help me out, I would appreciate it.
I'm looking for a film from my youth (80's or 90's) which I simply
can't trace. It had a villain from outer space, blonde I think, which had a handgun
that shot a long thin hose with a pointed metal end
that struck people either on the forehead or neck or chest and drained some
special fluid to sell in outer space market as a drug I think.
I think he wore some kind of  long overalls Matrix style, I'm not not sure. I
remember his character as a sort of "cowboyish" style (pardon the new word). 
I searched high and low for this film to no avail. I once thought the
actor could have been the late Richard Lynch but I could not find
any film in his database that matched what I am looking for. Maybe I am
not using the proper words to search for it because my native language is not
English. Anyway, maybe someone already knows what I am looking for ...
Thank you everyone. Great place you have here Andrew...

The gun details are off, but the rest matches.

WOW, that was spot on, Mofo Rising. Thanks for the reply.
I did not even remembered good old Dolph was in it.
Memory does play trick on you. You're right. The gun details was
completely off.
Once again. Thanks a million. Now off to Amazon uk....   :)
