A beam of pure antiprotons was an incredibly destructive weapon. Such a weapon was used by the so-called "planet killer" to destroy planets. ()

The  starships, which operated in the mid-to-late 24th century, had a spin reversal system that generated antiprotons. It was labeled on a schematic of the secondary hull of the  in 2365. (, okudagram)

The Crystalline Entity left behind a trail of antiprotons, by which it could be tracked across space. ()

Romulan disruptors left a characteristic trace of residual antiprotons, which could be used to date when the weapon was fired. ()

The deflector dish of  starships was charged with antiprotons. ()

The Jem'Hadar used antiproton beams to detect cloaked ships. ()

In 2372, The Doctor on the  used bursts of antiprotons from the warp core to reverse the effects of hyper-evolution on Tom Paris and Kathryn Janeway, by destroying the mutated segments of DNA. ()

The use of a cloaking device often left residual antiprotons that could expose the ship's presence. The Reman warbird Scimitar was equipped with an advanced cloaking device that left no such trace. ()
