FirstGen Three-Four

FirstGen Three-Four was a first generation Sentry.

In 2381, Three-Four was one of the Sentries that sent drones to meet the USS Titan's crew aboard FirstGen One-Five. Later, Three-Four fought against the Null when it made its final incursion into normal space. He was killed during the battle when the Null entered regular space right in the middle of Three-Four, ripping him to pieces.
