An encounter for almost any D20 Fantasy TTRPG.
This encounter works ideally where technology/science fiction elements are available. It can be played as humorously or seriously as the GM desires. This is not intended to be a combat encounter, but it is possible OO-P5 has a combat mode for when it logically deems hostility is necessary.
1. The find.
The group is mid travel when they find a large, round, silk sheet with strings attached to it. There is a hole in the center of the sheet as well that would seemingly serve no logical purpose as a bed sheet. The ropes all seem to be attached to a metal framed backpack suitable for a medium creature. It’s almost as if the sheet fell from the sky.

2. Further down off the trail.
A short while later, assuming the group is paying attention, they find a crater approximately 5′ in diameter. At the bottom of the crater is a dark gray, rectangular, metal box. There are no footprints around the crater and there’s no sign of local wildlife. It’s almost if the box was slammed into the ground by a greater force.
The box is very heavy. There are etchings on the box along with 00-P5 painted in black on one side. On the opposite side is a white button that seems to have survived the fall undamaged.
When the button is depressed, the box begins to shake a big. a port opens on top. A foot long metal rod with a small glass globe appears. “Bee=Beep Beep Beep.” is heard.
The globe lights up with each beep. The rod points the globe around at each party member as if looking them over before standing straight once more. “Bee-Beep Beep?” is heard.
Further investigation of the box.
If the group gives the strange “inhabitant of the box” no logical reason to fear them, its arms and legs will eventually protrude from its body and it will stand up. To the group it may seem like a strange golem or automaton. They will eventually be able to translate the robot’s beeping into a sort of rudimentary language. The party has gained a lifelong friend and ally or an oddity to be sold at the first opportunity.
While OO-P5 doesn’t seem terribly cold and lifeless, its logic processors can only handle so much. Emotions might be a bit too much. The real challenge of the initial encounter is to coax 00-P5 into trusting the group and coming all the way out of its box. Damage to its processing unit has left it unable to process its current whereabouts or origins.
Things the robot understands:
- Self preservation. (Parachuting from a crashing spacecraft, for example.)
- Preservation of close “friends.”
- How to assist humanoids without violating the first two principles.
- Threats to itself and friends.
- When communication is important to it.
- Basic machine learning. How to fire a crossbow. How to fix a cart. How to drive a cart. How to play simple games.
- What its physical and mental limitations are.
- How to use the rudimentary tools it is equipped with in order to repair itself.
- Understands most languages, just can’t record or speak back due to mechanical limitations.
- Small, furry, cute, cuddly, and innocent things are friends.
Things 00-P5 does not understand:
- Animal behaviors.
- Medicine.
- Magic. (Completely freaks it out.)
- Complex human emotions.
- Humanoid interactions.
- Why beings treat each other the way they do.
- How to speak anything other than “Beep.”
- How it got here.
- Religion, philosophy, psychology, or sociology.
00-P5 does not have any sort of flight recorder or memory technology to explain where it came from. 00-P5’s quantum particle battery will last for approximately 99 more years unless someone tampers with it. The robot is not armed, but will seem to understand how to operate a crossbow or ballista instinctively. Its sensor dome only extends 120′ in all directions and much farther when plugged into a starship sensor system.
It will do whatever it deems logically necessary or whatever its close friends tell it to do as long as it or no one else will get hurt as a result. It’s about as intimidating as a pair of bunny slippers in combat, appearance aside. It will always try to assist wherever possible by lifting, carrying or repairing things. 00-P5 can be used as a sentry in a pinch, although mileage may very when it comes to some humanoids and small, furry, innocent animals.
00-P5: Init +0; Atk +3 Fist melee (1d6); AC 14; HD 7d6 (36) ; MV 25’; Act 1d20; SP immune to mind control, regular heat and cold temperatures, eating, drinking, sleeping and breathing; SV Fort +2, Ref +1, Will +0; Approximate Str: 12. Int: 10. Equipped gear: Flashlight (lightbulb protrudes from chest.) Basic auditory, Infrared, UV, and visual sensors. Starship piloting and gunnery programming suites. Basic tools (Claw hammer, screwdrivers, knife, scissors, pliers, wirecutter, electrical tape.) Starship/computer interface ports. It also understands how to pack and use a parachute.
Additional uses: 00-P5 could also be a refugee robot in any given post apocalyptic or science fiction campaign. It will most likely appear as a relic from a long-past era or civilization.
There is a much longer backstory I will share about this robot at a later date. Have fun with it if you decide to run the encounter. Thanks for stopping by.
