|~ Jakoku aka the Grim Man.|
The Grim Man, also called Jakoku, is a Droid that Prince Diamond sends to capture Rini and one of the many villains in the Sailor Moon series. He has the appearance of a hooded, cloaked figure (though he looks slightly different from Wiseman) and uses a scythe.
He appeared in Sailor Moon R Episode 28 "The Secret of the Luna Sphere".
Diamond sent Grim Man into Rini's dreams to keep her asleep until he could capture her.
Sailor Pluto contacted the Sailor Scouts from the future through the Luna Sphere and transported them into Rini's dream world where the Sailor Scouts fought the Grim Man. None of the Sailor Scouts could even damage the Grim Man, until Sailor Moon, after saving Rini from falling to her death, attacked the Grim Man with her scepter, and then destroyed him with Moon Scepter Elimination. As was the case with Rubeus, she said: "Activation" instead of "Elimination".
- Grim Man physically resembles Wiseman and even has a similar voice. American audiences originally believed that he was Wiseman before the final episodes of Sailor Moon R were broadcasted in the US.
- Grim Man attacks Rini inside the dream world. This is similar to an iconic horror movie villain, Freddy Krueger from A Nightmare on Elm Street.
- Grim Man is one of the only three male Droids in Sailor Moon R.
- The way he disintegrates is different from the other droids. Instead of him shattering to turn a light blue color and then dissolve into dust, Grim Man disintegrates leaving only a crystal, which then dissolves into dust like any other droid.
- Grim Man is based on the mythical Grim Reaper.
- Grim Man was the final boss of Chapter 1 in the video game "Sailor Moon: Another Story".
