So far, we've seen the Hito Hito no Mi, Model: Male. What we haven't seen is the female equivalent, nor the Gyojin Zoan or the Giant Zoan.
Do you think we'll see these fruits anytime soon? The Gyojin Zoan would be absolute garbage other than enhancing the person who eats it's strength, but the Kyojin (Giant) Zoan would actually be pretty damn useful. The only person I can see eating the Gyojin Zoan is a Giant himself, so he could shrink down and sail on a ship like normal. Saul must've really had problems sailing on ships without being able to enter the cabins…
