Fictional character biography

Sentry-459

The Sentries' main purpose is to stand guard over military outposts and depots throughout the Kree empire. Sentry-459 accompanies a Kree scientific party who journey to Earth to experiment on sub-humans, which eventually results in the creation of the Inhumans. When the Kree leave Earth, Sentry-459 remains to monitor Inhuman progress, with the Kree intending to use them as a militia force. Sentry-459 remains inert until it is inadvertently activated by the Fantastic Four, who battle it to a standstill. Considering itself defeated when the Fantastic Four escape, the Sentry sends a signal to the Kree alerting them to the presence of superhumans on Earth before deactivating itself.^[1] The Kree Ronan the Accuser investigates the signal and battles the Fantastic Four soon after.^[2]

The U.S. Army transports the Sentry to Cape Canaveral, where it is reactivated by Yon-Rogg, a Kree colonel and the leader of an expedition investigating Earth. Yon-Rogg attempts to use the Sentry to kill his subordinate Mar-Vell, who manages to defeat it.^[3]

Ronan the Accuser later reactivates the Sentry and uses it in an attempt to reverse the course of evolution on Earth, but it is defeated by Mar-Vell.^[4] 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, who recruits it into his team Heavy Metal in a bid to destroy the Avengers.^[5] The Sentry returns in the Blackwulf series, having been found by Ultron and recruited into his Underground Legion. It is eventually destroyed in battle.^[6][7][8]
