Malroth, known in Japan as Sidoh (Japanese: シドー, Hepburn: Shidō), is a character in the video game Dragon Quest II.

He also appears as a main character in the game Dragon Quest Builders 2 as a young man with no memories, assisting the protagonist in surviving and rebuilding a world, while grappling with strange voices and his inability to create things.

[citation needed] Malroth first appeared in the video game Dragon Quest II as its final boss.

He accompanies the protagonist, a builder, who had previously been a captive on a boat owned by the Children of Hargon, who Malroth assists on their quest.

However, he himself is not capable of building, electing to destroy things and fight monsters to help, high fiving after major accomplishments.

This culminated in a betrayal by a character named Warrick, a knight who professed to support the builder but was secretly in the Children of Hargon, who manipulated various people to get Malroth put in jail after he began losing his composure and making dangerous, irresponsible choices.

Working with the monsters inhabiting it, the builder creates an ark to save them, as well as going to Hargon's castle to find Malroth.

It is then revealed, however, that this was part of Hargon's plan to remove the humanity from the monstrous Malroth, allowing him to achieve his full power.

[5] Voice actor Nobuhiko Okamoto, while discussing famous monsters in the series, identified Malroth as one he liked, though noted the frustration of his use of Fullheal.

[9] Meristation writer Sergio Gonzalez appreciated Malroth, discussing how, despite having a villainous face, he was more than a companion, suggesting that he was an unforgettable character.
