Shout-outs and references from the games in the Dragon Quest series.
- The NES version has NPCs Howard and Nester from the Nintendo Power comics.
- In Chapter 3, Torneko can recruit a pair of mercenaries named Laurel and Hardie.
- The kingdom of Gardenburgh was renamed Femiscyra in the retranslation and is a secluded island kingdom populated almost entirely by female warriors.
- Dragon Quest Heroes: Rocket Slime contains shout-outs to other Square Enix-published series, such as a Platypunk ally named Ducktor Cid (a reference to the recurring character name in Final Fantasy) and the hero goes up against a tank with a treant-like appearance called Chrono Twigger (an obvious reference to Chrono Trigger), whose in-game logo even resembles the Chrono Trigger logo. These two are notable because the series referenced were formerly Square series, whereas Dragon Quest was an Enix series.
- Dragon Quest Monsters has a breed of Slime called a Slimeborg. Resistance is futile.
