Rigor Mortex

Rigor Mortex

Rigor Mortex is a superboss in Dragon Quest Monsters Joker 2 and the source of most of the conflicts that torment the inhabitants of The Island.

Backstory

It was the creation of a madman named Zelham as an attempt to gain control of The Island from the tribe he rivaled, who had Leonyx as their leader. While it managed to corrupt Leonyx's soul, the machine also consumed its creator. Leonyx managed to save his heart by turning it into a Sanguini and sending it away, but his soul was still posessed.

Rigor Mortex is a three-spaced giant monster and easily the hardest boss in the game. It's also the most complicated to synthesize as it requires a Leonyx and a Zenith Dragon, both of which require monsters that at one point required a Captain Crow. Since there's only one Captain Crow per game, it's impossible to get with just one game card.

Super Light

In Dragon Quest Monster Super Light, Rigor Mortex reappears as the main antagonist of the first two arcs of the game, it is responsible for driving the monsters hostile. It hides behind the Ancient Seat. Rigor Mortex is eventually confronted by the hero and his/her monsters, and the mysterious machine said that it want to 'become one' with the hero and fight him/her, Rigor Mortex is eventually defeated and fell into the hole behind it, which lead to the underworld.

Trivia

• The monster's name is based of the word "rigor mortis". Possibly a portmanteau with "Libranex", its japanese name.
• He is one of the few monsters that overpower Nokturnus .
• The battle theme for Rigor Mortex would be later reused for the optional post-game super boss against Awakened Ludo in Dragon Quest Monsters : The Dark Prince as part of the game's post-game epilogue story that primarily takes place within the Whispwoods.
• It could be theorized that the usage of this theme is meant as some form of homage to preceding Dragon Quest games that influence the plot of this game in some way, in the same vein as Psaro's final phase theme being used during the fight against Evolved Randolfo as a homage to Psaro the Manslayer, the final boss of Dragon Quest 4 that takes place in the canon timeline where Psaro was too late to save Rose from a bunch of humans due to being unknowingly stalled and deceived by a Succubat masquerading as her.
