Spoiler warning! This article contains plot details about events that occur later in the game.
Nuclear Plant Omicron is one of three nuclear plants in the Tandor Region. It is only accessible through triggering the CURIE and Urayne event after defeating the eighth gym.
Since you can use the island to level up your pokemon rather fast, you should choose your party before leaving for the island.
One of the two remaining Nuclear Plants that still function after the meltdown of Nuclear Plant Epsilon. It is located to the west of Tsukinami Village.
This is the first location you will discover CURIE and Urayne.
Main Quest
This event is part of the main storyline and cannot be skipped.
Upon being sent to Nuclear Plant Omicron, you are tasked to help defeat all of the Nuclear (type) Pokémon that are threatening the Tandor Rangers, Theo, and the Tsukinami Village Gym leaders.
Have you seen all the bugs in Tandor? Give me a call if you find any new ones!
Once completed, the Nuclear Pokémon surrounding Kellyn and the other Rangers will run away. The power plant will then explode with a beam of radioactivity.
CURIE and Urayne make their first appearance. Cameron appears and tries to fend off Urayne's attack, but ultimately gets injured when he protects Theo from being killed. CURIE and Urayne flee from Omicron after failing to obtain what they wanted: Uranium cells. Professor Bamb'o will give both you and Theo HM02 Fly, and you will be sent back to Bealbeach City's Tandor Ranger Union.
You will be unable to return to Nuclear Plant Omicron after this event.
