I have done some comparisons with my FM and KO brethren. It is all a matter of proportions to scale. If I use G1 FM, G1 Prime, and G1 Jazz as givens to measure the scale they represent against themselves Then to stay in that same ratio I get the following: Here is the standard. G1 FM, G1 Prime, & G1 Jazz Here is the next in the line. Metroplex sized FM KO is close to Legends size if I try to keep the same height ratio of FM rime:Jazz In this case im using THS Convoy as it is the closest that I have and could think of that would work for this situation. His proportions are a little off than G1 prime, but if you guys can come up with a better choice than THS Convoy let me know. Then here is the final set that I would consider WST. This is "Uranus 5 changes" that is the KO name on the card he came with. With my WST Prime and WST Jazz
