Monstrous Physique — Annihilator Robot (SF)

Hello! I hope you enjoyed the fun break with our Guest Takeover for the past few weeks. I’m back in the writing seat, refreshed and ready to make more monsters for you! One of the monster types I really like most are constructs. In particular, I’m a big fan of robots! Who doesn’t like a big robot? Starfinder is full of robots, but it lacks one of Pathfinder’s most iconic robots. If you look at the banner above, you’ll see the annihilator robot, probably the most famous robot in all of Numeria. I’m going to stat it up for Starfinder!

An image of an annihilation robot. It is an enormous robot that resembles a robot.

Booster Jets (Ex) As a swift action, the annihilator robot gains a fly speed for 1 minute. It can use this ability up to 10 times per hour.
Chain Guns (Ex) The annihilator robot’s integrated firearms have a range increment of 200 feet. These weapons can’t be disarmed.
Force Field (Ex)
The annihilator robot’s force field functions much like a standard force field, except it remains inactive for 24 hours when reduced to 0.
Plasma Lance (Ex) The annihilator robot can fire a 120-foot long line of plasma from its tail as a standard action. Creatures in the area take 20d6 electricity and fire damage. A successful DC 22 Reflex save halves this damage. The annihilator robot cannot use the plasma lance again for 1d4 rounds.
Suppressing Fire (Ex) The annihilator robot fires a large spray of fire in a 100-foot cone as a full action. It makes a single attack roll with its chain guns and compares it against the AC of all creatures within the cone. Creatures who are hit take 6d6+13 piercing damage.

The enormous and formidable annihilator robots roam old ruins and wastelands, ridding them of all life and civilization. They smash structures, slaughter creatures both sentient and bestial, and scorch plant life to ashes. When rampaging, an annihilator indiscriminately destroys rather than following the meticulous approach many other robots take with their work. Despite the destruction they wreak, annihilators often gather up those who survive their assaults, collecting the dying and unconscious from battlefields and bringing them to a set location. Their purpose for keeping these battered still-living prisoners is unknown.

That’s it for this week! If you end up introducing the annihilator robot into your game or you have any request for a future Monstrous Physique, please drop me a line at
