i was always looking for the source of this one since 2011

I also had one that seemed from 80s or early 90s due to the style, but i lost it in a computer crash.
It had a weird robot guy (like those classic DragonBall mechs) killing some female elves ( a pair of female soldiers, one that looked like Bulmas mom, and another that was sleeping on a bed) if anyone knows the names of thse 2 mangas, please drop me a bone
