Time-Space Control skill
The Garnet Rod
Time Stop was the third and final taboo of Space-Time over which Sailor Pluto had control. Queen Serenity explained that if Sailor Pluto were to use the power time would stop for a short period, but once it resumed she would die.
The first time Time Stop was used was when she, Sailor Uranus and Sailor Neptune were in a helicopter that became under attack. The helicopter than exploded, but at the moment it happened, Sailor Pluto stopped time. After a brief conversation with Uranus and Neptune, she transported them to the roof below. Once they were safe, time resumed and the helicopter was blown up, with Sailor Pluto still inside it.
Time Stop was used in the Black Moon arc of the manga when Prince Demande took the two Silver Crystals from Black Lady and tried to touch them to one another to destroy the space-time continuum. Sailor Pluto used Time Stop to stop him and gave Usagi a chance to take the crystals away. When time resumed, Sailor Pluto died, which made Black Lady remember her true self, revert back into Chibiusa and then to transform into Sailor Chibi Moon.
Time Stop was used in the following video games, always by Sailor Pluto. However, the user doesn't die after the attack's execution:
