The Kree Sentries first appeared in Fantastic Four #64 (July 1967) and were created by Stan Lee and Jack Kirby.

Sentry-459 accompanied a Kree scientific party that journeyed to Earth to experiment on sub-humans (which in turn created the Inhumans).

The Sentry was seen again when activated by the Super-Adaptoid, who used the robot as part of his team Heavy Metal in a bid to destroy the Avengers.

Only six feet tall, this Sentry was programmed to prevent any space travelers from Earth from finding the remains of a hidden Kree city on the Moon.

[10] This Sentry only appears once, and battles several members of the Imperial Guard before being damaged by the West Coast Avengers.
