tecnicoly speeking this is not a rematch because showa godzilla  and gamera and hiense godzilla and gamera are not the same such as if oliver queen (arrow) and batman (nolanverse) battle and so do batman (comic) and green arrow both are green arrow and batman but they are two differnt incarnations plus this has showa ultraman.
