In an alternate timeline, Voyager is attacked by Krenim forces shortly after the activation of the astrometrics lab. For nearly a year, the ship is under constant attack and becomes barely functional, forcing most of its crew to abandon ship. The timeline is restored after Voyager rams and destroys Annorax's weapon ship. (VOY: "Year of Hell", "Year of Hell, Part II")
  • Investigating a subspace compression, the Defiant is taken over by the Jem'Hadar. Fortunately, the miniaturized USS Rubicon is able to stop them before they reached a Dominion base. (DS9: "One Little Ship")
  • Voyager is attacked and boarded by the Hirogen, who wish to use the ship's holodecks for holographic battles. They use the crew as participants in the simulations, and reassign their identities to fit the scenario. The ship is later returned to control of the Starfleet crew in exchange for a holographic generator. (VOY: "The Killing Game", "The Killing Game, Part II")
  • Voyager's crew is duplicated by the "Silver Blood" on a Class Y planet. Shortly after their departure, the duplicate crew leave the planet and eventually lose memory of their origins, setting a course for the Alpha Quadrant. (VOY: "Demon", "Course: Oblivion")
  • Voyager passes through a Mutara class nebula, a transit which takes approximately one month. All crew except for Seven of Nine and the Doctor are placed in stasis in order to counteract the detrimental effects of the nebula on organic tissue. (VOY: "One")
  • An alien named Arturis attempts to trap the crew of the USS Voyager on a phony Starfleet vessel, called the USS Dauntless. His deception is revealed, but Voyager learns the use of quantum slipstream drive technology, which allows them to travel several hundred light years closer to home. (VOY: "Hope and Fear")
  • The USS Defiant responds to a distress call from Captain Lisa Cusak of the USS Olympia. Although it is discovered she has been dead for years, she has a great impact on Deep Space 9's senior staff. (DS9: "The Sound of Her Voice")
