You can't tell me what to do I'll draw all the Joestars as werewolves if I have to--

Do you know how big Giorno would be as a wolf? Really small. He'd only be around 5'9-5'10 and that's really short compared to the others. Even on the tips of his paws, he'd only ever reach Jonathan's shoulder. Definitely didn't take after either of his parents there, but he does boast one of the strongest strains of the werewolf gene from Jonathan's side, so his transformations retain their monthly schedule rather than erratic like a lot of the family.

He also probably had a custom collar and tailpiece made. I don't know why, but I feel like he would get that done so people (mostly foes) can recognize him as he struts around at night or something idk
