Third Research Institute

The Third Research Institute was a laboratory on Punk Hazard where Vegapunk performed experiments for the World Government. After Caesar Clown ruined the island with his gas weapon and the government's abandonment Caesar made it his base of operations for the Underworld.

Layout and Locations
On the frozen side of the island the research institute is built into the base of a mountain and has a natural harbor in front that connects to the river. The building was originally the lab in which Vegapunk carried out his chemical weaponry experiments, but now it is used by Caesar as a hideout and for his immoral research. There are many different levels and rooms in the building, and each building is surrounded by balconies with chemical chimneys on the roofs. The building is marked PH-006 along with a gaping hole on the right side. Due to being on the cold side of the island, most of the facility is covered in snow and ice.

Past


Years ago, Kaidou, the Uo Uo no Mi, Model: Seiryu user, and Alber, a lunarian, were held captive in the facility and underwent various experiments. One day, Kaidou decided to break out and recruited Alber into his crew.

Vegapunk extracted Kaidou's Lineage Factor and replicated his Devil Fruit, but considering the artificial Devil Fruit a failure, Vegapunk stored it in his secret control room and later abandoned it when Punk Hazard was evacuated. Years later, Kozuki Momonosuke snuck into the room and ate the fruit.
