Ok so I don't know if this has already been made but I've seen this picture on X and had an idea.
I don't know what this creature would be named but I think it's the serpent Dory and Brogy talked about in little garden. My main theory about that is that we can see 6 heads with one main big head. I would presume the main head is Imu, the 5 others are the gorosei. Imu cut his 5 others heads to create the gorosei and give them part of his powers and that's why he was able to retrieve Saturn's powers, because it's part of his own body.
