Location: Dressrosa City Area
Petitioner: Quiz Researcher Zoner
Reward: Varies; see below
Objective Reward: Varies; see below

The end of the road. In order to unlock this final instalment of the Grand Line Quiz series you need to complete two prerequisites:
  • Finish each of the previous three Side Stories: Kid, Lady, and Madam.
  • Complete the main story events of Dressrosa, then return to the city in Chapter 9.
You'll find Zoner - who looks very different this time around - in the "Old" Royal Plateau Area of Dressrosa City Area. It's the road in the northwest of Dressrosa, and Zoner is standing a short ways north of Blacksmith Road. The appearance is different, but the objective is the same as always.


Level 1
  • What is the name of the place in Dressrosa where gladiators fight? The Corrida Coliseum
  • What is the name of the violent fish that lives in the sea near Dressrosa? The Fighting Fish
  • What flower blooms in the garden nea the Dressrosa Royal Palace? Sunflower
Reward: Merchant Gelato, 37,000 Berries
Objective Reward: 50,000 Berries

Level 2
  • The current Ultimate Force of Marines HQ are Kizaru, Ryokugyu, and? Fujitora
  • What are the dwarves who live in Dressrosa called? The Tontattas
  • Who is the man called the strongest gladiator of the Corrida Coliseum? Kyros
Reward: Fruit Gator Punch, 49,000 Berries
Objective Reward: 50,000 Berries

Level 3

In the final level of the quiz you'll discover the truth behind Zoner's radical form changes. You'll then have to rescue them from some baddies. Head to the south end of the Coliseum, then check the chunk of road overlooking Square, At Fountain to find the Kidnappers. They're a weak bunch of Technique users who will fall easily to your Speed users.

Defeating the goons and freeing Zoner will bring the Grand Line Quiz Side Stories to an end at last, and you'll learn the full answer behind the identity of Zoner. Well done.

Reward: Treasure Chest Key, three Luffy's Cube Fragments, 74,000 Berries
Objective Reward: Perfected Shabby Ball Plus


Treasure Chest Key

It's nice to receive all of the money and rewards associated with Zoner's many quizzes, but by far the most valuable item you receive by completing the Grand Line Quiz Side Stories is the Treasure Chest Key. This important item allows you to open the locked, red chests scattered throughout One Piece Odyssey, of which you've probably seen many as you explored the game. You have a lot of backtracking to do to open them all, which is a lengthy undertaking that we'll discuss in another guide.
