Dragon Quest Wiki

The slaughtomaton is a recurring monster in the Dragon Quest series, first appearing as a boss in Dragon Quest VII at the depths of the Automaton Stronghold.


Slaughtomaton is a green mechanical monster that appears like an armored knight with an oni face in the center of its chest. The machine has a helmet with purple horns on top of its head and dual wields a pair of swords with purple handles and hilts. Its feet and the top half of its demonic face are sea green and it has eye-like structures on its helmet, shoulders, and knees. The mouth opens back and forth to reveal its sharp fangs and a purple tongue. The Slaughtomaton is a force to be reckoned with, as it is capable of blinding its enemies and using a variety of deadly attacks, such as breathing fire. Its design also bears a resemblance to Psaro the Manslayer's fifth form.

The Slaughtomaton is the trump card that Tinpot Dictator uses against the party. Just by summoning it, the Slaughtomaton kills the Tinpot Dictator. It then sets its sights on the party. However, it is defeated as well, shutting down and disappearing for good.

The party fights this battle right after defeating the Tinpot Dictator and so losing this battle means that the party must defeat the Tinpot Dictator again (in the 3DS remake, the slaughtomaton can be fought directly after losing, without fighting the Tinpot Dictator if you already defeated him). Conserving MP and Herbs from the last fight is instrumental.

The Slaughtomaton can use Flash which, if it hits, can decrease the accuracy of the party. It can breath flames, causing 15-20 HP. Every so often, it will use 2EdgeHit which is a devastating attack, doing about 40-50 HP. However, some damage will be reflected back to it.

Maribel should use Sap although it has a slight resistance to it. Kiefer should use Psycheup/Fireslash on the enemy. The Hero should attack, stopping only if a party member is low on HP. Gabo should constantly attack, stopping only if the party is really hurting and the Hero and Maribel can't heal fast enough.

Keep with this strategy and victory will be yours.
