He might be in his strongest form yet, he let his Devil Fruit take over him cause
failure is not a option here..
That's why Kaido asked Luffy who he was.. To be certain that Nika didn't take control over him..
So all Zoan Awakenings have 2 forms similar to when unawakened, Hybrid Awakened and Full Zoan Awakened form..
Kaido must also know someone or himself where this happened before..
Anyway Saturn is even more dangerous now than he was before..
