I know we've talked about this, and I think somebody posted a custom or two using a Buzz base for D6, but I grabbed a single-card Izzy Hawthorne to try it out because it's a smaller fig than Buzz. Almost works if you figure D6 is like 6'4" normally, and then add a couple of inches of armor plating on his feet and grabby mechanical hands instead of gloves.
But wanted to give you guys a sense of scale if you were considering doing a custom.
She was on sale/clearance for $7 at WM, so figured I'd try it out. Will give this guy a paint job and then throw him in the storage bin never to be seen again
