Thanks. I don't know if I've ever seen smaller Mazingers in Guardian style, but there are smaller Guardians made in Italy (Ceppi Ratti). I'd love to see the Maz ones, though.
Yes, I have seen those, but these are actually the robots that belong inside Guardian normally but with Mazinga styling haha. So maybe you could get a stacking Mazinga. I don't know if they'll actually fit though.
