2. Zoids (First appearance: 1982)
Zoids combined a Japanese penchant for mecha with a childhood fascination for all things beasts, dinosaurs and construction. Essentially miniature IKEA robots, Zoids in the hands of a reasonably adept child would rapidly transform from flat-pack plastic kit to motorised angry thing, only occasionally getting snared on the carpet like a confused Ray Harryhausen creation. In the UK, there was even a comic, detailing precisely why terrifying mechanical Triceratops Redhorn the Terrible wanted to gut Mammoth the Destroyer.
