Intelligent invertebrates?
Yes, mister, billions of them! Vast swarms of these man-size creatures lurk under the surface on planets they infest, as they rapidly burrow deep underground with their incredibly powerful second set of digger legs. Most are workers, but a select handful, a mere few millions, are warriors, with a small but deadly autocharged blast-gun implanted below their abdomen - only the most seasoned professional Terran soldier can tell a warrior hidden within the teeming billions of workers. Shooting is surprisingly accurate, aided by the eight eyes of the warrior that encircle the thorax. The gun only holds a few shots, but it's all it takes. (And usually the bug is killed before it can get off more than a few shots anyway!)
Expertly sculpted by Black Crab's Aaron Brown, each Arachnian model can be constructed as a harmless worker or deadly warrior. Models may be built with straight abdomens (shown) or curled, and either may attach the deadly blast gun, the straight abdomen concealing the weapon until that deadly moment of surprise fire, the curled one ready to fire it over the back of the warrior, scorpion-like. Two sets of pedipalps are also supplied, folded (shown) or extended. All of these piece options are included with each model!
Large packs of Arachnians are also available to make huge swarms inexpensively. These will be perfect monsters for sci-fi bug hunts, fantasy or Pulp Lost World scenarios (with the guns left off, of course!), etc.
To save you the trouble, each limb piece is provided with a sturdy pin cast on, with some drilling (with a pin vise or similar) necessary to insert these long pins into the thorax for a good tough join. Long mould pins on the bottom of the thorax and abdomen can simply be snipped off during construction.
Thorax (front body part) is approximately 15mm front-to-back. There is a small flat platform hidden on the bottom of the thorax to elevate the bug, so that the weight of the model is not supported by the legs.
Garn love to kill these creatures, and then pop the body parts straight into the fridge!
