A great plot might be that the Dark Eldar capture the Terminator and try to use his technology for their own evil purposes. But the Terminator has some hidden protocols that activate when he's in danger of being used against his original mission. So he has to fight his way out from within the Dark Eldar's stronghold. There could also be a plot where the Terminator teams up with some of the more noble races in the Warhammer 40K universe to take on the Dark Eldar threat. This would involve a lot of interesting character dynamics as the Terminator is used to working alone.
Well, imagine a plot where the Dark Eldar somehow manage to corrupt the Terminator's programming. He then becomes a tool for their dark deeds. But a group of heroes from both the Terminator's world and the Warhammer 40K universe team up to try and restore his original programming. This would involve a lot of action - packed battles as they have to fight through the Dark Eldar's defenses. Another exciting plot could be that the Terminator is sent to the Dark Eldar's dimension as a sort of experiment. He has to find a way to survive and escape while constantly being hunted by the Dark Eldar. The Terminator's struggle against an entire alien race in an unfamiliar environment would make for a great story.
Well, it's really hard to say. The Terminator is a super-strong and almost indestructible cyborg with advanced weaponry. But the Dark Eldar are very sneaky and have some really cruel and powerful weapons in their own right. I think it would depend a lot on the setting. If it's in a more open, modern-day Earth setting, the Terminator might have the edge because his tech is more in line with that environment. But if it's in the Dark Eldar's home turf in the Warhammer 40K universe, they could use their knowledge of the terrain and their devious traps to take him down.
One common theme is the clash of different powers. The Vampire Counts have their undead and necromantic powers, while the Dark Eldar are known for their sadistic and high - tech ways. So, a story might focus on how these two very different power sets interact in battle or in a political intrigue within the Warhammer world.
You can try some popular fanfiction websites like Archive of Our Own (AO3). It has a large collection of Warhammer - related fanfics, so there's a good chance of finding Vampire Counts vs Dark Eldar stories there.
