Animal · 2 hexes · SM +1 Giant Scorpion [Monsters on Automatic, SRD coverage: vermin and monstrous arthropods; answers Giant Scorpion (SRD 5.1)]
Two and a half metres of black chitin that holds you with the claws and takes its time with the tail. The shell turns most weapons, the pincers do not let go, and the sting is what actually kills — everything before it is the scorpion arranging matters to its satisfaction.

Notes
- GCS ancestry draft: gcs/giant-scorpion.gct
- Independent build total: -25 points of racial traits plus 4 points of racial skills.
- Answers the SRD heading(s): Giant Scorpion (SRD 5.1). Only the creature identity is taken from the SRD; the GURPS statistics, ratings and prose are this project's own work and reproduce no SRD text.
- Typical Stats, damage and ratings are derived from the racial template, not authored beside it, so the sheet and the stat block cannot disagree.
- Body mass used to scale this build: 120 kg. ST, Size Modifier and DR are checked against it; see the gurps-animal-sanity-check skill for the bands.
- Movement: ground Move 5 (primary). The published Move is the primary medium's cruising Move; sprint figures are stated here and not folded into it.
- Treasure and grappling are not authored for this batch and ship as explicit nulls; `lair` carries a short habitat note, because where a wandering animal dens is an encounter fact rather than a loot one.
- About 2.5 m including the tail, which is the SM +1 row.
- ST from Basic Lift: it drags a human body into a burrow.
- Rating caveat for review: the giant spider out-rates this creature, which is not obviously right. The cause is in the rating path, not the build — a binding is scored at its raw ST while a disabling ability is scored at one point per five, so the spider's web (ST 16) contributes 16 while this scorpion's lethal venom (30 points) contributes 6. Only the better of the two is counted per creature, so the spider's own venom is also discarded. Recorded rather than tuned around; the fix belongs in the CER path.
- Added after a post-hoc comparison against independent GURPS fan conversions of this creature: Peripheral Vision. The comparison surfaced the gap; the build is still ours.

- Description
- Written by Dungeons on Automatic, released under cc_by_4_0
- Independently authored GURPS build. The SRD supplies the creature identity this record answers to and nothing else: no SRD statistics, wording or presentation is reproduced, and no third-party GURPS conversion was used as an input.
- Answers the SRD heading(s): Giant Scorpion (SRD 5.1).
- Racial template: -25 points across 22 traits, plus 1 racial skill(s) worth 4 points.
- Every trait is drawn from the project's controlled GURPS vocabulary in scripts/srd/trait-library.mjs, which carries the page reference and published cost for each entry.
- sourceSystem is recorded as doa_fixture because that is the package contract's value for project-authored material; the SRD headings this record answers are in provenance.coversSourceIdentities.
- Ratings are recomputed through the consumer CER path on every build, so a mechanics change cannot leave a stale rating behind.
