I bought some KO Aerialbots from Sirtoys, they're awful quality.
They are lacking many articulations compared to the original molds, but these are super easy to disassemble and reassemble together, which was an interesting exercise I wouldn't just do with an original figure.
Starting off there is only a couple of screws on the torso area holding the arm pegs and waist swivel together. Everything else can be popped off just by looking at it.
