i would say its not like cloning but more like dna modifing to be larger while the chamber rapidly causing dna replication to grow the zeny to big boy zeny. could say something very complicated but im not a biologist.
i never belive that a full sized zentran cant stand up on its own weight i see them like as dinosaurs. using what i remember about that thread, if someone goes jurrasic park and clones dinos we be seeing like another horror movie of dino flesh sliding off bones.
