... but they can be saved (in my opinion anyway)... they have a lovely tall and slender look about them compared to the majority of other 28mm figures (which looks horrible in the rest of the humanoid MU range, but works with these guys) and reminds me of the Cybermen from the 8th Doctor comic strip The Flood which was a complete absence of the 'man in a suit' look.
Now, the first obstacle is the legs, the figures as a whole just aren't sturdy for wargaming and the legs are a major let down - so they come off at the knee... luckily the thigh armour has a flat edge and is the perfect hidden join....
the thigh is then drilled - now drilling this soft bendy plastic is tricky as you don't so much drill as slice... yanking the drill bit out rather than turning the bit brings some of the plastic out with it and leaves a bit of a hole for you to work with. You need to go as far into the body as you can, but you need to be careful of your drilling going awry (on the plus side if you have an exit hole where you don't want one, it will normally seal up). Stick in a good thick (unbendy) bit of wire - if the wire has a sharp end it will go further into the plastic than the hole if you're not careful...
... and do the same with the lower leg and foot - you just need to maintain a central drill point which is easy enough I reckon (I did experiment with drilling without the amputation, but the plastic tended to misdirect the drill bit and after a certain distance in, I couldn't guarantee where I was going to end up)...
.... and repeat for the other leg (if you look at the rear of the knee joint, the right leg has a small stubb which is absent from the left leg which is a useful observation). I've not glued until this point, just add superglue to the join and the wire seems to be enough, just slide the lower legs up to meet the thigh and position it so it becomes as close to the original as you care to have it. Leave some wire at the feet to connect to your chosen base.
Next is the hands... no stage by stage here - sorry... but cut off the deformed club hands from hell at the flared cuff. Again wire is drilled into the arm, but I use a smaller diameter wire because it has to fit into the replacement hands - which come from the Gangs of Mega-City One Street Gang sprue. The G0MC1 range is a bit variable in scale and the hands from the plastic sprue are perfect for the Cybermen - other 28mm hands look to big on the arm and too human, these at least look right and painted silver should look fine. Of course they will be smaller than any other figures hands, but that works for me as they are essentially robotic replacements for real hands and it helps move the figures away from the man in marigold gloves look....
I haven't worked out what to do about the bendy arms yet, but with the legs reinforced, I'm happy with what is now a sturdy piece... with a bit of variety on the position of the arms and the head, I should be able to come up with some variety between models... I even have some partially cybernised humans on the work table...
