Dressrosa Underground Trade Port

Profile

The vast undercity beneath Dressrosa: a scrap heap where discarded “dead” toys, garbage, and the “rebellious losers” (defeated colosseum fighters) are dumped out of sight, housing a factory and trading port worked by transformed minions, and the deposed King Riku faction’s hidden base (“Riku Army Operations Base, Flower Field,” p. 14). King Riku warns of “an even deeper darkness beneath this” (p. 13), and Doflamingo’s men suspect “more secrets underground” in a structure this large (p. 10). The defeated gladiators are routed here by a giant toy/automaton enforcing the Donquixote programming — “power-type” fighters sent to the factory and trading port (p. 11).

Key chapters

• Ch. 726 — first named + shown: the scrap-heap undercity / trade-port + factory beneath Dressrosa; the deposed King Riku’s hidden Riku Army base; the dumped toys and defeated fighters; the “deeper darkness beneath” tell. Seeds The Colosseums Defeated Are Secretly Dumped Underground.
• Ch. 732 — Robin and Usopp, guided by the Tontatta dwarves, infiltrate the undercity via the Flower Field tunnel and find it “like a gigantic PORT TOWN” (p. 19) — the hidden factory and an underworld trading hub run on “JOKER” (Doflamingo) backing. The transformed living toys are worked here as forced labor, hauling cargo and begging to see their families (pp. 16–18). The House of Toys passage and the Flower Field tunnel both lead here.
