Nebulandia

Nebulandia is a non-canon island in the New World.

Geography
The island is composed of several rocky mountains, which the Marines converted into outposts.

It contains a plant which is triggered by Devil Fruit users. The plant will try to wrap around them, which will weaken them. When night falls, the geyser in the middle of the island spews a mist of seawater, and the mist nullifies all Devil Fruit powers. As pointed out by Komei, this island is a bad place for people with Devil Fruit abilities to enter.

History
Komei captured Zoro Sanji, Porche, and Hamburg and took them to this island, and the other Straw Hat Pirates as well as Foxy and Kansho went to rescue them. Komei nearly succeeded in capturing all the Straw Hats and nearly killing Luffy. However, Brook, Tony Tony Chopper, and the other Foxy Pirates came to the rescue. The pirates fought off the Marines as Luffy defeated Komei. The pirates then left the island.
