Well, not exactly a full retard, but seriously crippled casualty, I purchased this one today.
All the parts I need to restore a couple of other figures are here: head (including all 4 mouth parts), both torso halves, tail and the left leg. Looking closely at the photo I can see the right leg is severely damaged at the hip, but I don't need a spare one of those. Oh, and the screws in its back will come in mighty handy, too.
This mangled Karcass was cheap. Only USD50. BARGAIN! lol.
Looking forward to this 'Alien derelict' arriving in a couple of weeks. Along with 2 other junkers in similar condition I purchased recently.
