This includes all forms of Buck Rogers in the 25th Century, from the comics, books, the 1939 serial film, the 1979 pilot movie, the 1979-1981 show, and more. This is also important because the Buck Rogers in the 25th Century Wiki is dead, is missing several articles and categories about the franchise, is stub-ridden, and the only recent edits in the last 30 days are from me, Dimensionalizing Multi-Dimensional Entity, who also happened to put over 60 articles in the Article Stubs category. Please, watch the episodes and DO NOT rely on the Buck Rogers in the 25th Century Wiki, since almost all articles on there are missing a ridiculous amount of information, and that wiki only has 2 administrators, who appear to be inactive.
The 1979-1981 NBC television series has mostly One-Shot Villains that appear in only 1 episode, but the most prevalent villains are the ones from the 1979 theatrical pilot film of the show, the Draconians Princess Ardala, Commander Kane, and Tigerman, who only appear for six (Tigerman four) season 1 episodes, they are: Awakening (Episodes 1 & 2); Escape from Wedded Bliss (Episode 12); Ardala Returns (Episode 17); and Flight of the War Witch ((Tigerman absent) Episodes 23 & 24).
Since I finished watching the whole show (including the pilot film), I shall now list villains from the show other than the Draconians, but it may not be all the non-Draconian villains from the show, and unfortunately, I will be too busy doing other stuff to make these articles, but please also make a Buck Rogers in the 25th Century template to put in the article navigations, as there are multiple versions of some characters.
