Serpent
Serpent is part of the old Power Zoids line, which featured Zoids from the UK Zoids comic that was being produced during the 1980s. And Serpent is a model I've been wanting to get my hands on for years. It's just such an unusual design and it has an interesting movement mechanism. When you flip the switch on, Serpent rolls along at a pretty quick pace. Apparently it came with a little bit of plastic that helps it stay up when it's not in movement, but as you can see in these photos, it just takes a moment or two of balancing the model correctly and it can stay perfectly vertical on its own.
