so this babys stand could fight with GER and it would end in a tie because if giorno goes up to the baby he will get smaller. Then the babys stand will crush then when he is small enough but giorno could just use GER to go back to where he was farther away but he couldnt actually damage the baby. the only way giorno could stomp on this babys skull is if the baby finds intrest in him and plays with him as thats the only way for you to not get shrunken and then crushed by the babys stand. another way giorno could win is by turning him to a fetus but i dont think thats possible and i dont think giorno would do that
