Do you mean their zoan form? If so, then ses, hybrid forms are the strongest form of a zoan user!
Kaido's hybrid form was first deployed against the Worst Generation and it was strong enough to overpower all of them at once. This ability is what makes him the strongest of all creatures in the world and a true menace in battle.
Mythical Zoan-type Devil Fruits are the rarest subtype of the Zoan class in the One Piece world. Thought to be even rarer than the Logia types, the Mythical Zoan-type Devil Fruits offer quite interesting abilities that allow the users to turn into a mythical creature or their hybrid at will.
Known to be the rarest type of Devil Fruit in the entire world of One Piece, the Mythical Zoan is up there with the strongest powers to exist in the story. As the name suggests, these Zoan Devil Fruits offer the powers of mythical creatures, which is what makes them incredibly unique.
This Devil Fruit is rightly termed to be the most ridiculous one to ever exist in history and Luffy has been able to defeat the likes of Kaido with it in an even contest. He also went on to defeat Rob Lucci with rather ease with this power. It is, arguably, the strongest Zoan Devil Fruit in the story.
To everyone's surprise, Luffy, who was always believed to be a user of the Paramecia type Gomu Gomu no Mi, is actually a user of a Zoan type Devil Fruit. Furthermore, this isn't just any Devil Fruit, but a power described to be "the most ridiculous" to exist in the entire story.
It is incredibly difficult to awaken a Zoan type devil fruit, but there are a handful of One Piece characters who have been able to pull it off. Devil fruits are an incredible source of power for those who want to become stronger than everyone else.
Even then, the vast majority of the Logia type of Devil Fruits are exceptionally powerful. One Piece has recently introduced the concept of Awakening and, with it being the ultimate form of Devil Fruit powers, it is only a matter of time before fans see the awakening of a Logia type of Devil Fruit as well.
One Piece finally answers a question that has been splitting its fanbase for a long time, by giving proof that the powerful former Yonko, Kaido of the Beasts, never actually awakened his Devil Fruit.
Crocodile said that Awakened Zoans are regular zoans who somehow enhanced their abilities. Maybe the demon guards don't use a Rumble Ball, but the series has shown that a rumble ball is not needed to make a partial transformation or a different transformation that is not of the three zoan stages.
We know that Pell said, in tthe Alabasta arc, that there were 5 Devil Fruits that could grant the ability to fly.

One Piece shows a new awakening of a Zoan-type Devil Fruit, confirming that Luffy's version of this rare and powerful ability is absolutely unique. Kaku's awakened form shares an important future with the one shown by his CP0 companion, Lucci, highlighting how different Luffy's Gear Fifth appearance is.
Luffy uses a new attack called "Gomu Gomu no Gigant" to transform his whole body into a giant. He looks like a God. Earlier we learned Luffy's body releases a strange vapor, which is supposedly for the resurrection of his devil fruit.
First and foremost is Smoker, who is sadly one of the coolest Logia users but also by far the weakest. If Smoker wasn't so simplistic in his thinking, he could easily take out any non-Logia opponent by surrounding them with smoke with no escape.
This Devil Fruit is quite powerful and allows her to become a giant spider at will. As with all the Ancient Zoans, it packs tremendous power and durability and moreover, gives her the ability to trap people in her webs.
One of the earliest Mythical Zoan Devil Fruits to be introduced into the series, the Tori Tori no Mi, Model: Phoenix, consumed by former Whitebeard Pirates first mate Marco, allows its user to transform into the mythical blazing bird.
Queen is one of the All-Stars of the Animal Kingdom Pirates. Like the other All-Stars, he too possesses an Ancient Zoan-type devil fruit.
Is Luffy Gear 5 the strongest? Yes! Of course, Luffy's Gear 5 is the peak of his colossal powers. He can literally do ANYTHING with his devil fruit powers right now, as he transforms into the Sun God Nika when using Gear 5, making his devil fruit the strongest in existence so far.
