Sentry bots are heavily armored and well-armed machines. Their original purpose was to be built and serve in the military of another world known as the United States. They were created by their creators known as RobCo Industries to be one of their most dangerous and finest robots.

The sentry bots are found in a building known as the Robco Factory, and it was summoned into our world by a group of xenophobic humans that wanted to use their summons to try and kill the monster girls. Unfortunately for them the factory appeared on them essentially telegraphing the entire group of humans participating in the ritual.

The factory and its robots would be later affected by demonic energy and would turn into sexy women as a result including the sentry bots. They still had their cold personality but they are rather loyal to their husbands if they managed to find a man they fancy.

The sentry bots alongside the combat-capable Protectrons, Mister Gutsy, Assaultrons, and Securitrons.

Sentry bots are heavily armored meaning they are very resilient to all forms of attacks. They are armed either with either a minigun or Gatling laser on their right arm and a missile launcher on the left. They also have three legs with wheels at the end that allow them to traverse though they are slow. They also have a self destruct sequence to prevent themselves from being captured by blowing themselves up.

They have gray skin color, red eyes, and silver hair as well. They have the three mechanical legs of their original form, including the same gray armored plating on their body but can separate these platings when having sex with their husband and easily put it back on afterward. Their arm weapons can come out of their arms in hidden compartments under their skin. They also have artificial origins akin to the private parts of a female that allows them to have sex with their husband.

There also exists another variant of the sentry bots known as the next-gen sentry bots. These variants of sentry bots still have the same personalities as their predecessors but gain new upgrades.

They still hold the same weaponry such as the minigun (but it's tri barreled) and the missile launcher, though some have both mini guns on their left and right arms. They now possess dual back-mounted mortar launchers that can launch grenades at their enemies.

The next-gen sentry bots thicker armor meaning they are more resilient than their predecessors and not only this but they are much faster with their wheels being able to traverse through all sorts of terrain. They are also physically stronger meaning they can deliver powerful close quarters blows to their enemies. Their explosion during their self destruct sequence is just as powerful as mini nuke as well. They can even independently turn their top body with their lower body like a turret as it moves about gunning intruders down in all directions.

The next-gen sentry bots have army green skin color, red eyes, and lime green hair as well. They have the three mechanical legs of their original form, including the same army green armored plating on their body but can separate these platings when having sex with their husband and easily put it back on afterward. Their arm weapons can come out of their arms in hidden compartments under their skin. They also have artificial origins akin to the private parts of a female that allows them to have sex with their husband. What separates this variant from their predecessors is that they are bigger and have bulkier armor than them.
