For Starfinder: Squimic the Mimic

So, I wrote Squimic for an adventure back in 2018. The idea was that in a grey experimental base, the PCs would find Squimic in a lab, the result of a project the grays did not yet considered a success. I wanted to introduce an NPC gun that would talk to characters and grow with whoever carried it. But, my idea was complex, untested, and would have required GMs running followup adventures to ad lib Squimic’s responses since the authors of those adventures were writing them at the same time I was, and had no idea Squimic existed and thus could not include any guidance on how it would react to the events they were writing about.

Ultimately the developers who did a great job polishing my raw text into a finished adventure simplified Squimic into a “Living Transmutation Matrix,” and I think they did the right thing. An idea can be fun and perfect for some groups without being the right fit for every adventure.

But, since that adventure came out years ago (and was released under the OGL), I feel comfortable presenting my original open content version of Squimic here, for anyone who thinks a little mimic gun buddy is a good match for their campaigns. I’ve included all the text that would have been in that adventure if they’d gone with my version, including background information on the project and how the PCs were to find and interact with Squimic, but not any of the plot points, proper nouns the publisher used, the adventure name, or any of the other material the publisher marked as Product Identity in their Open Game Content declaration.

Squimic was found in a lab where it had been consistently used by a robot to shoot troll polyps.

S.Q.U.I – Mimic

A search reveals a dirty and battered data-tag, marked SQUI-mic, with further information encoded in a small computer chip. A close examination shows it actually says “S. Q. U. I. – mimic,” though the periods and first “mi-“ were concealed by dirt. Anyone can use a comm unit in their armor, or any tier of computer, to read the full encoded information stored in the tag. This reveals it is for a Special Qualities Unified Initiative Mimic. It’s clear the project name is “Unified Initiative,” the branch of that project that created this project is the “Special Qualities” division, and the test subject is a mimic.

In fact, Squimic is the only even-partially successful prototype of a special project to create small, cybernetically-enhanced mimics that could switch between taking the form of tiny creatures (especially vermin, rodents, and pets), and useable technological devices. The grays hoped to be able to breed these creatures to serve as tools of their espionage agents, but were concerned about Squimic’s intellect and independent motivations. They hoped repeated exposure to threats that required assistance (in the form of the robot arm) would cause Squimic to “normalize” the concept of just doing what they are told.

Though Squimic is a living, sapient creature, they lack the ability to move or take most actions. Mostly they just take the form of various small arms, and shoots at things someone wielding them aims at and pulls their trigger (though Squimic can refuse to carry out such attacks if it wishes to). As a result, squimic is much closer to an item with some special rules than a creature, and is treated as such in its description.

Squimic can become any item level 1-3 small arm or basic or advanced melee weapon of light bulk or less that it is familiar with, and which uses batteries (of any capacity), darts, flares, petrol, rounds (of any kind) or scattergun shells as ammunition. It is currently familiar only with those the grays programmed into it (including all such presented in Chapter 7 of the Starfinder Core Rulebook, along with the tactical switchblade, wire garrote, personal cryospike, red star solar brand, subzero hail pistol, frost subduer, bruiser decoupler, bombard shellgun, vapor cavatation gun, bravado handcannon, and explorer handcoil from Starfinder Armory). Regardless of what kind of weapon Squimic is, they can accept any size battery, and use the battery for all ammunition usage of the weapon they are emulating (using the energy to generate darts, round, shells, and similar physical ammo as needed). Squimic can learn another weapon if it can examine one in detail over 10 minutes, and it meets all their other requirements.

Squimic can have one “ready” form they can assume as a full action (currently a vapor cavatation gun), and it can take any other form over the course of ten minutes. Squimic’s ready form can be changed with an 8-hour period of “downtime” that functions like sleep.

Squimic is currently treated as an item level 5 weapon for purposes of hardness, HP, saves, and so on. They act as though they had a tier-2 computer with an artificial personality for purpose of what skills they have and at what bonus. They count as both a weapon and an aberration for purposes of what spells and effects can function on them, and if an effect can work on both the caster may choose how to treat Squimic.

Squimic can grow in power if someone provides enough UPBs for it to eat and makes a successful Diplomacy check (DC 15 + 1.5x Squimic’s current item level). Squimic can never be of higher level than the number of ranks in Diplomacy of the character attempting to convince them to grow, and the highest item level small arm or melee weapon of light bulk they can become is always their current item level -2. Squimic’s effective computer tier is always equal to half its current item level.

Squimic can only consume raw UPBs, or functioning and fully-repaired weapons, armor, and armor upgrades. Items must have an item level no greater than Squimic’s item level +2, and if they have an item level lower than Squimic’s -2. Squimic gains only 10% of the UPB value of the item. The total UPBs Squimic consumes determines their maximum item level.

Characters may well have questions for Squimic, which they answer to the best of their ability. Some typical questions and answers are detailed below.

Q: Who are you? (or What are you? Where did you come from? What’s your name?)

A: “I don’t know! I woke up next to a broken tube, and everything was shaking. There was a tag on the tube marked “SQIU-mic,” so I guess my name is Squimic.”

Q: How can you become a functioning weapon?

A: “Oh, I can become all sorts of things! They just… appear. In my head. And if I think real hard, I turn into them! I… I don’t know how. Or why.”

Q: Who created you? What are your plans now? What can you tell us about this facility?

A: “I don’t know about anything outside this room. There was some sirens and explosions earlier, but I didn’t go look what made them. I have no idea where I come from, or why I was brought here, or what I am going to do next!”

Q: Why were you a plasma pistol?

A: “I kept being put in that broken case with those squirmy things, and they’d try to hit me! And there was this robot arm that would squeeze me, so I became different guns with the robot hand pulling my trigger, to see what would keep the squirmy things from hurting me, and this worked the best.”

Squimic has no hostile intent toward the PCs, though they defend themselves if attacked. They are afraid to explore beyond this room by themselves, and are unwilling to be sent anywhere on their own, but are willing to accompany the PCs, and even act as a weapon for a character as long as the PCs promise not to use them as an expendable scout or abandon them.

Squimic is happy to help, as long as the PCs treat them reasonably well (not sticking them in a bag, not using them to look around dangerous corners, and so on). Each time Squimic feels abused its attitude toward the PCs goes down one step (beginning with neutral), and it takes a Diplomacy check to improve. Squimic functions as a standard weapon for anyone they feel neutral or better towards, but refuses to function for anyone they feel unfriendly or hostile towards.
