Ensemble Darkhorse: Aside from Star Saber, Kakuryu and Hellbat seem to be the most popular characters. The former even received a toy in the United EX line, twenty years later!
Hype Backlash: Went through this to a degree. In the early days of the online fandom, when the series wasn't widely available, Victory was widely claimed or assumed (mostly by people who had never properly seen it) to be the darkest and most mature Transformers story, and something of a holy grail that was too good for Western shores. When the series became more widely available, it was found that Victory was just as kiddie as any Transformers cartoon, and in some ways it was one of the more childish ones (the ending theme is about whether Star Saber wet the bed when he was a kid). It still has a strong fanbase, though, which appreciates what it actually was rather than what people assumed it was.
The Scrappy: Several fans dislike Jan as a very annoying kid, in contrast to the previous series' Shuta. While Shuta does contribute by being a Headmaster Jr., Jan is often seen as The Load by others.
Surprisingly Improved Sequel: It's generally regarded as the best of the G1 anime series; it's much better-paced than either Headmasters or Masterforce, its animation is some of the best in the franchise, and its plot is a fun romp rather than a slog or a vague mess.
Values Dissonance: Killbison and a human farmer each give the finger a few times. In Japan, at least at the time, the gesture wasn't considered offensive, but it would be completely inappropriate in a kids' show in America and several other countries.
