As far as I know, DIAclone was a line in japan that took the transformers and gave them different colours. So, in short, it was a rip-off. But, here's the interesting part, one of them was the ultra magnus figure. The prime-based part was all blue, but the armor gave it an optimus prime feel. Then, years later, fan-based transformers retailers made their own power-up suits based on the DIAclone. Instead of using an all blue prime, though, they used the regular figure. And that's how the DIAclone suit came to be. In order to allow the suit to fit on the model, you need to take it apart a little, and then put it back together with the new pieces. Unfortunately, the matrix has to be taken out and combined with the hands in an unusual way to make way for the new chest. Sorry, still no instructions.
