I wasn't sure about posting these four, since only two of them were in actual anime series (and even then, one of those used a different character model at that time)... but, still.
The one on the left is a re-deco of a design seen in the same show as that on the right, but for a character from an earlier series.
No, he doesn't come with that sword!
That last guy's alt mode is pretty damned cool...
There are a
few more pics I have elsewhere, too.
