"Scorpion" is a two-part episode of the American science fiction television series Star Trek: Voyager that served as the last episode of its third season and the first episode of its fourth season (the 68th and 69th episodes overall). "Scorpion" introduced the Borg drone Seven of Nine and Species 8472 to the series. The title is an allusion to the story of the Scorpion and the Frog, which Chakotay tells Janeway (replacing the frog with a fox) as a warning against attempting to cooperate with the Borg.
