- Name meaning
- English compound 'Frontier' + 'Dome' (gairaigo, フロンティアドーム). Surface: a hemispherical defensive barrier ('dome') sealing Egghead's labophase. 'Frontier' carries a deliberate double sense — a defended border/perimeter (the laser grid fires the instant its boundary lines are crossed) AND the scientific frontier / cutting edge (Vegapunk's most advanced tech). The 'sealed-border' reading pays off when the closed Dome becomes a no-escape killbox for York's massacre (1079).
Structural lore — the automated laser-grid defensive system surrounding Egghead’s labophase (the research level above the clouds). One of Vegapunk’s perimeter defenses, first shown Ch. 1068.
What we know
- Ch. 1068: The Frontier Dome projects a grid of lines around Egghead’s labophase; the instant an enemy crosses a line — BEEP — the system “activates a laser beam” and fires on the intruder (p. 13-14).
- Ch. 1068: Kaku of CP-0 is caught and burned by the Frontier Dome after Stussy declines to warn him (p. 13-14) — the system’s first on-page demonstration.
- Ch. 1068: Fielded alongside holographic “space-monster” decoys over the island — part of Vegapunk’s automated defensive tier.
- Ch. 1069: The Frontier Dome is the domed area of Egghead the Vegapunk side steers the Straw Hats into — toward the Vacuum Rocket, an extraction transport, to get them off the island amid the CP-0/Marine threat (p. 15).
- Ch. 1071: The Dome is part of the island’s “Labophase defense system.” It is deactivated from the control room by an unseen operator — dropping the barrier at the moment Vegapunk’s life is in the balance and admitting CP-0 (Lucci/Kaku breach and strike the Thousand Sunny, blocked by Zoro); the crew flag the “too convenient” failure as possibly a trap (“Is someone in the control room?!”). Satellite Shaka restores the Dome — “The Frontier Dome has been restored… Shaka” — but too late (pp. 10-13). See Egghead Frontier Dome Deactivated By An Unseen Hand.
Chronology / structure
- A perimeter sensor-and-laser grid enclosing the labophase (above the clouds), distinct from the sea-beast weapons that patrol Egghead’s waters. Together they form the island’s automated defense in depth.

- Who can deactivate the Frontier Dome, and can it be turned against intruders or used to seal the island? **
