Chapter 1,027: "Danger Beyond Imagination".
In the cover, Nami and Leo are making a t-shirt for a lion cub who is next to his father (they are Minks). All of them are in a store called “Haute Couture Nami” and the t-shirt design is the lion-sunflower that Bell-mère made for Nami when she was a child (in the clothes she inherited from Nojiko).
Chapter starts in the “Flower Capital”, there people are enjoying the festival. Tenguyama asks Toko if she is having a good time, she says yes while she eats a candy. We see a little flashback of the moment when Tama leaves Wanokuni with Speed in a boat towards Onigashima. Tama tells Tenguyama that she has to go help, although she doesn't know if she will return. Speed says she will protect Tama. Back to the present, Tenguyama wonders if Tama is safe.
The sky in the “Flower Capital” is covered by clouds, so the people at the festival can't see that Onigashima is approaching to the capital.
Cut to Onigashima's rooftop, we see a Mary (a man from Kaidou's army) that is observing the battle and reporting the situation to the rest of his companions. His voice is amplified to be heard throughout the castle.
Mary: "Report about the mysterious dragon!!
Right now on the roof is the wounded young Yamato.
And in the sky there is something incredible... two dragons face to face!!
The blue dragon is Kaidou-sama!!
And pirate “Straw Hat Luffy” is riding a pink dragon!!!"
Yamato looks at Momonosuke as he remembers some words Momonosuke said to him when he was still a child.
Momonosuke: "If only I could turn into a monster like him...
it would be such a help to everyone!!"
The Mary keeps talking, saying that the identity of the pink dragon is unknown but there is no doubt that it is an enemy. We see Queen surprised at the Mary's report.
Queen: "Was Yamato the one who stopped Kaidou-san?"
Back to the battle between dragons. Kaidou opens his mouth and prepares to shoot his “Bolo Breath”. Luffy tells Momonosuke to shoot something from his mouth too but Momonosuke has no idea how to do it. Kaidou finally shoots his “Bolo Breath” and Momonosuke barely manages to dodge it.
Luffy says something to Momonosuke that shocks him (we don't know what) and then jumps towards Kaidou. Luffy blows up his left arm and attacks Kaidou with his “Gomu Gomu no Elephant Gun” hitting Kaidou's head (that crashes into the ground). Momonosuke thinks about what Luffy told him.
Luffy: "Hey Momo!!
Bite Kaidou!!"
Momonosuke: "I can't, I can't...!!
I...!!"
Momonosuke remembers Kaidou's assault at Kuri's castle after Oden's death and how Kaidou attacked his mother. That's when Momonosuke musters up enough courage and gives a strong bite at Kaidou's body.
Kaidou: "Uwaaaa!!!"
Kaidou screams in pain, Momonosuke remembers the moment when Kaidou told him that his father was a fool of a lord and bites him harder. However, Kaidou turns around and looks very annoyed at him.
Kaidou: "What do you think you are doing!!!"
