M.O.G.U.E.R.A. (モゲラ Mogera)
Though he's certainly no Mechagodzilla, I quite like Mogera. He poses little threat with his shrewish face and lumbering movements, but his design is impressive and refreshingly bizarre in both his iterations.
Incredible transformation from I Vampiri
A bit stilted and stiff, I Vampiri is certainly far from Italy's best genre offerings, but it does feature some inspired moments. Perhaps the most impressive sequence is this incredible transformation.
