## Fictional character biography
### Sentry-459

The Sentries' main purpose is to guard military outposts and depots throughout the Kree empire. Sentry-459 accompanies a Kree scientific party that journeys to Earth to experiment on sub-humans, which in turn creates the Inhumans. When the Kree leave Earth, Sentry-459 remains to monitor Inhuman progress. Sentry-459 remains inert but observing until it is activated by the Fantastic Four, who fight it to a standstill. Considering itself defeated when the Fantastic Four escape, the Sentry sends a signal to the Kree before deactivating.
The Sentry is then transported by the U.S. Army to Cape Canaveral, where Kree colonel Yon-Rogg reactivates it in an attempt to kill Mar-Vell, one of his subordinates. However, Mar-Vell manages to defeat it.
Ronan the Accuser later reactivates the Sentry and uses it in an attempt to reverse the course of evolution on Earth, but it is once again defeated by Mar-Vell. The Kree agents attempt to retrieve the Sentry, but are driven off by S.H.I.E.L.D. The Sentry is later activated by the Super-Adaptoid and joins his team Heavy Metal in a bid to destroy the Avengers. It returns in the Blackwulf series and joins the Underground Legion, but is eventually destroyed.

### Other Kree Sentries
#### Sentry-9168

Another Sentry - designated 9168 - is encountered by the Fantastic Four on the Moon. This Sentry is smaller than traditional Sentries, being about the size of a human, and is programmed to prevent space travelers from finding the remains of a hidden Kree city on the Moon. The Fantastic Four battle and destroy the Sentry via a remote destruct mechanism.

#### Sentry-213

This 30-foot (9.1 m) tall Sentry was stationed in an unmanned supply depot/surveillance post on the planet Uranus. It was destroyed by a group of Eternals led by Uranos, sparking a war with the Kree.

#### Sentry-372

This Sentry only appears once, and battles several members of the Imperial Guard before being damaged by the West Coast Avengers. The Sentry then self-destructs and destroys the outpost it was guarding.

#### Sentry-571

This version aided the Kree when their "Lunatic Legion" attacked Earth. It was defeated by Iron Man.
