Blake's 7, Series Three

Tarrant:
Is that a weapon?

Avon:
That? No, no, it's purely defensive. An analogue of something that evolves on the permanent dark side of a planet. A highly simplified copy of course.

Tarrant:
Permanent dark side? Are you saying you've...

Avon:
I've built an artificial Sopron. Yes, that's what I'm saying.

[Zen informs Servalan that the module is marginally better equipped than Liberator]

Avon:
Self defense. Some animals bristle out their fur to frighten their enemies. But that doesn't count for much in the dark.

Vila:
So what does Sopron do?

Avon:
Sopron is a mirror. A distorting mirror. It reflects a slightly greater image of whatever it is that happens to be scanning it. Zen saw a capacity-charged brain, because that is what Zen is. Orac saw a highly sophisticated computer because that is what Orac is. Cally thought that she saw her parents, But what she actually saw was herself.

Tarrant:
And will that work?

Avon:
Oh yes. The question is... what will Servalan see? And will she be fooled by it?
