Despite the rough start with cog and the mandatory partsforming ones the current junkions and rock guys are really good transformers figures, and excel in not their intended features but rather their ability to combine with others in unique ways, creating a lego-like third dimension to these figures that just make them the best imo.

Hasbro needs to think up of more of these and to orient them towards their ability to combine rather than their ability to act as armor pieces, as they seem to lack in that advertised feature.

Picrel is a combiner I made of magmatron, crashbar and scraphook
