I used CloneTroopers as "armored troopers" in the Transformations dio. They were NOT from the SW, but rather, just duders as part of an alien force.

I used a couple of Microman figures to act as villains in Transformations.

Now, the key sometimes, is NOT to use strict 3.75" figures for the dios. There are a lot of toylines that aren't 3.75". Like, I was using Spiderman's Ultimate Lizards (or whatever they were called) because I wanted monsters and they are BIGGER than the Joes. Same w/ Alien Racers's red monster dudes. IF they were actually 3.75", they wouldn't be nearly as menacing, scary or destructive.

I'm using McFarlane's Cyberunits for the current dio and they are working well enough. These are NOT 3.75" and if they were, they wouldn't work at all. Gotta look outside the 3.75" realm for my dios!
