The locations we’ve seen in Oda’s One Piece are truly amazing, and the author has demonstrated a very intriguing skill in crafting his locations. And while some of them are, so to say, similar to some others, Oda was nevertheless able to consistently provide each of them with at least a small touch of originality. Introduced later in the series, Egghead Island nevertheless managed to become one of the most important locations in the whole series, as well as one of the most intriguing ones. The central part of Egghead is the Labophase laboratory and in this article, we are going to tell you what it is and explain its structure.

  • Article Breakdown:
  • Labophase is the central location on Dr. Vegapunk’s Egghead Island. It is the laboratory where all the important experiments on the island are conducted and serves as Vegapunk’s base.
  • The Labophase is protected by the Frontier Dome, a series of powerful lasers with enormous destructive power; only those who have consumed the Pika Pika no Mi are immune to them.
  • The Labophase consists of a total of three interconnected buildings – Buildings A, B, and C. Each of them has several floors, and there is also an underground laboratory that serves as a basement.

Labophase is the center of operations on Egghead

Vegapunk’s Egghead Island has one of the most interesting layouts in the whole series, as far as locations are concerned. Visually, Oda really made an effort to make Egghead intriguing and we can only confirm that he was successful in his endeavor. The central part of the island, the Labophase, is what we are going to talk about in this article.

Labophase is the main laboratory on Egghead Island. It is used by Vegapunk and his Satellites to conduct the most important experiments on the island, which is why it is such an important place. From there, they can also monitor the whole island and are connected to it, but the laboratory itself is heavily guarded, and access to it is restricted, which makes sense, seeing how important of a location it is.

The Labophase laboratory is protected by the Frontier Dome, an exceptionally powerful defensive system that consists of a group of extremely powerful lasers; only those who have consumed the Pika Pika no Mi, seeing how they become light themselves, are immune to the Frontier Dome – everyone else will get injured. The lasers’ power can be modified on a scale starting with 000 (deactivation) and ending with 100 (maximum output).

The laboratory itself consists of three interconnected buildings simply titled A, B, and C. There is also an underground laboratory as well. Each of the buildings consists of several floors, which is why the structure of Labophase is so complex. In the next section, we are going to explain the overall structure to you, so that you know every detail.

Labohphase’s structure explained

In this section, we are going to go over the general structure of Labophase and explain each segment so you can know your way around it.

Building A

Building A is the main building of the Labophase, consisting of more than four floors, making it the largest one as well. We know that the second floor is focused on the research of Organoids, synthetic organs used for medical purposes, while the third floor is used for research of synthetic minerals and diamonds used in industry. The fourth floor contains the control room from which Vegapunk can monitor the whole island. There is also an underground laboratory which was formerly used for Devil Fruit research.

Building B

The second building, Building B, has a total of three floors, but sadly, its structure has not been revealed in detail. We do know that the second floor of Building B contains the weapons research facility, but nothing else was revealed about this building, so this is – sadly – all we can provide you with at this moment.

Building C

The final building of the Labophase, Building C, also consists of three floors but its structure is even more enigmatic than that of Building B. Namely, we don’t know anything about it. We do know that Pythagoras was attacked by S-Snake on the third floor of Building C, but we have no clue what it was used for.


There is also the Room Nikyu, which holds a paw-bubble formed from Kuma’s memories and is located somewhere in the Labophase, but we don’t really know in which building, so we can’t provide you with more details.
