Nubon

Nubon is a dwarf from Tontatta Kingdom who first appeared on Green Bit.

History
After capturing Usopp and Robin and bringing them to the Tontatta Kingdom, Nubon was seen with the other dwarves searching Robin's body while she was pinned to the ground. They released Robin when she promised that she would not harm them. However, since she could not provide a weapon, the dwarves were going to strip her. They stopped when Flapper told them that she is a friend of the "hero".

The dwarves later requested Usopp to help them fight against the Donquixote Pirates much to his unpleasant surprise. An army of dwarves assembled and while bringing Usopp and Robin along, traveled through an underground passage to the Riku Royal Army HQ located beneath the flower field where they rendezvous with Thunder Soldier.

After they arrived, Nubon listened to Thunder Soldier's speech about overthrowing Donquixote Doflamingo|Doflamingo]].

He and the other dwarves present listened as Gancho described their past history concerning their slavery under the Donquixote Family and their liberation by the Riku Family. After Gancho's speech about stopping Doflamingo from repeating his ancestor's atrocities, the dwarves cheered vigorously, ready for battle.

After Thunder Soldier explained about Riku Dold III's dethronement and Dressrosa's tragedy in detail, the dwarves' plans, which Thunder Soldier dubbed "Dressrosa Operation SOP", were then revealed. They planned to infiltrate the underground world through a tunnel they created and defeat a Donquixote Pirates' officer known as Sugar, the Devil Fruit user who turns humans into toys.

When it was time to commence the decisive operation, the dwarf rebels, Thunder Soldier, Usopp, and Robin entered the tunnel and later arrived at the underground trade port. The dwarf rebels then split into two groups. One group remained with Usopp and Robin while the other group, including Nubon, went with Thunder Soldier to go to the royal palace to assassinate Doflamingo.

The group with Thunder Soldier boarded a lift to the royal palace and were later confronted by Lao G. Thunder Soldier and the dwarves fought him, but they seemed to be outmatched.

The lift later reached the royal palace and Lao G continued to have the upper hand. When the palace shook due to Pica's confrontation with Luffy's group, some of the dwarves, including Nubon, took the opportunity to pin Lao G down, enabling Thunder Soldier to move forward.
