The Gyrinx is an alien creature from the Rogue Trader rulebook, resembling a large ginger cat. It bonds with characters, and then had the power to store psi points, and augment shooting, close combat, and initiative by +1. I have added the rules from the rulebook below. The background to the Gyrinx was that it was some kind of familar-empathic creature which formed a symbotic relationship with it's 'owner'.
Miniature wise, it was released in 1987, but more as a limited edition mail order miniature. I do recall that in 1990 there was a 'sticker sale' in my local GW shop (Brighton) as part of a wider promotion, and there were one or two Gyrinx included in the RT601 Adventures and Pirates packs, as well as Jokaero. Like an idiot I did'nt buy them at the time, and I only managed to purchase my Gyrinx this year.
Sculpting wise, it's a big fluffy cat. The sculpting is good, but there's not much else to say about it. I am not sure who sculpted it, but they did a good job. Painting wise, it's described as a big orange-ginger fluffly cat, with blue eyes, and that's how I painted it. I did take care to tone down the orange with a sand coloured highlight to stop it looking too much like a fox. More contempary takes on the Gyrinx have it blue and white, but I chose the old Rogue Trader look. It will probably end up with my Space Slann.
