Chainclaw supposedly has an armour mode. Fold the arms down so the upper arms are besides the body. Bend both the knees and the hips backwards. Fold the legs out to the sides so they're alongside the arms. Yes it's a block. But it's a block that doesn't quite fit together properly and looks a bit of a mess: if they'd wanted to make a piece of block armour they should have made the arms able to fold away inside it and for the sides to fold against straight.
Fortunately there's an improvement when we get to the vehicle weapons mode. Fold both the knees and hips back. Fold the arms back and clip the hands onto the small pegs at the side of the knee. Place the Mini-con socket underneath onto one on a vehicle. What you get is a dual missile array with 4 moulded missiles in each half of the array. The missile array looks like it's supported by the arms at the side of launcher and will even pivot upwards with them in place. Lovely piece of design.
Icepick & Chainclaw's instructions show Chainclaw with the same weapons mode for use with the robot, presumably due to Icepick's lack of 5mm hands. If we assume that the 5mm peg on Chainclaw's back is meant to be a handle to be held with then there's a couple of options for a hand held gun mode. Straighten the robot out with the arms by the sides for an elongated look. Alternately place the robot in a sitting position by bending the hips forward and the knees back then lock the hands onto the side of the knees for a more compact look. We'll find out which is right when Chainclaw's repaint comes out with a different commander.
Dodgy armour mode. But the rest is very good and I'd like several of the weapons modes to attach to various toys.
Fab repaint. I want.
