Geomag Kor Proteon is a sub-series of Geomag Kor. It has the same building principle, with plastic blocks assembled around a metal ball. Proteon sets, hovewer, have much more extra pieces, like limbs and heads, to attach to the basic form. Basic pieces are the same ones as in other Geomag Kor sets, so you can mix them and use the pieces together to create even more creatures.
