Right as TGS 2025 week started, Square Enix shared a new Dragon Quest I and II HD-2D Remake trailer that highlighted a new Ocean Floor area for the second game in the series. Now it shared new screenshots and details about the Mermaid-focused storyline and extra Hargon’s Champion boss that appear under the sea. While this update didn’t note exactly it will come up during the adventure, the screenshots do show all four members of the party are present during it.
Apparently, at one point in Dragon Quest II HD-2D Remake story, the players will happen upon two mermaids in a cove. The pair of them will introduce us to Mersea, an underwater city where that race lives. Hargon is causing trouble down there too, with his monsters and Champion Mariella threatening them. We’ll then head underwater to the city to help the Mermaid Guard fight back, explore shipwrecks, check the depths of the ocean, and face Mariella to ensure that area also remains safe.
Here’s the latest batch of screenshots showing what to expect from the Mersea and Ocean Floor adventures.
Square Enix also shared official art of Mariella.
Dragon Quest I and II HD-2D Remake will come to the Switch, Switch 2, PS5, Xbox Series X, and PC on October 30, 2025, and TGS 2025 runs September 25-28, 2025.
