- Cyberpunk: The original series was set in pretty much this kind of future before cyberpunk even became a widely used term.
- Uncanny Valley: Buddy's girlfriend—revealed as a robot, disassembled, boxed, and still talking inanely about how she wants to be his friend. Even knowing what she is, he weeps for her.
- The Woobie: Buddy Blank.
- Too Good to Last
- Unbuilt Trope: As many fans will tell you, the original 1974 series used a lot of tropes that wouldn't become common until much later. In fact, one of the most common reasons given for its Too Good to Last status was that it was too innovative, to the point that seventies audiences ended up being completely lost at concepts like Kill Sats, Ridiculously Human Robots, Corrupt Corporate Executives Unfettered by the law, and even a creepily prescient plot centering around a water baron (which is totally a real thing, though the real ones don't use laser beams).
