I remember buying saving up to buy a Voltron toy as a kid. It was a very small model with plastic lion limbs that did not transform or detach. It was basically a toy robot with lion slippers and mittens.
Still, I thought it was the greatest freaking thing ever. Unfortunately, I have no idea where the heck it could be. Anyhow, I can’t wait to try modeling and printing a replacement. I really like Tony Buser’s idea of modifying the Leonardo Robot as a starting point.
