List of characters from Grim Tales from Down Below

Note: Only list characters that have a significance to the story. If its a cameo, leave em out.

Main Cast

Junior (a.k.a Grim Jr)

The main character of the story and Grim and Mandy's son. Prince of the underworld.

  • Brother-Sister Incest: Implied though he heavily denies it.
    • By the end of the series he seems more accepting of it. When the series renewed they seem to have worked out a brother-sister version of a Two Girl Romantic Friendship.However Mimi is also his Crush so it could be a love Triangle.
  • Brought Down to Badass: Offers up his demon powers in Afterbirth in an attempt to regain his sister's love. It works.
  • Dem Bones: A living skeleton like his father. His spirit form is more human looking though. Because he was originally human, but Grim's plans called for killing him and bringing him back as a reaper.
  • Anti-Sue/God Mode Sue: Junior's defining traits are his jealousy and loathing of his beautiful and talented little sister. By the end of Grim Tales, Junior has all of Minnie's powers and adoration, as well as a claim to the throne.
  • Driven by Envy/The Resenter: Is jealous of the almost genuine Parental Favoritism that Nergal Jr. shows Minnie, and would give anything to have Nergal Jr's powers.
  • Expy: Of Shinji Ikari and Ichigo Kurosaki.
  • Future Badass: From the Afterbirth previews, he seems to have gotten far more skilled.
  • Go Through Me: After Mandy drains the dark energy out of Mimi, reverting her to her human form and orders her to be disposed of. Junior, tired of her callousness stands in front of Mimi and refuses to move even when Mandy starts physically beating him.
  • Grew a Spine: Pun aside, he made a daring choice to summon his demon-reaper powers to defend a weakened Mimi from a pissed-off Mandy. It's also because he made that choice that Mandy actually decides to spare Mimi.
  • Grim Reaper: Like father, like son.
  • Heel Realization: Though it takes a trip through the afterlife for him to finally realize it.
  • Humanoid Abomination: Is a walking skeleton with an Eldritch Abomination attached.
  • "I Know You're in There Somewhere" Fight: Against a mind-controlled Minnie.
  • Lovecraftian Superpower: His Nergal powers.
  • Mismatched Eyes: Minnie gives him one of her eyes. So he has one pupil in one of his socket.
    • In human form he has one blue and one grey eye to represent this.
  • Nice Job Breaking It, Hero: Its due to his jealously that the comics events happened.
  • One-Winged Angel: Was about to get serious here before a Cooldown Hug.
  • Super-Powered Evil Side: Minnie's Nergal powers can take over him if he's not careful.
  • Talking to Themself: Talks and argues with his Negal side.
  • The Worf Effect: Gets tossed aside by nearly every baddie he meets.
  • The Unfavorite: He feels like this due to his sister. In truth its not the case.
    • If what the Nergal symbiosis says is true, Jr. standing up to his mother made him the favorite in her eyes.
  • The Hero

Minnie (a.k.a Mini Mandy)

Grim and Mandy's daughter though technically Nergal Jr's the father, Junior's sister, and princess of the underworld


The very same from The Grim Adventures of Billy and Mandy. In this universe, after years of unwilling servitude to the two title characters, he found he actully did like hanging around them, especially Mandy. At first he was unwilling to kill them, allowing Mandy to live into adulthood. He eventually gathered the nerve to reap her, but not before proposing to her first. She accepted and the two have the ruled the underworld since.

  • Bumbling Dad
  • Butt Monkey: Yeah even as the ruler he can't get a break. Not as bad as the TV show though.
  • Dem Bones
  • Even Evil Has Standards: He actually calls Mandy out for letting Mimi get close to the Hand of Horrors knowing full well what it can do.
    • Give another to her for not helping Blossom and Mimi during their hour of need in the past
  • Grim Reaper: Duh.
  • Papa Wolf: Loves his kids very much and will do anything to protect them.


Grim's Wife and mother to Junior and Minnie. After years of bossing Grim around, she found out he had an attachment to them. As such she was immortal since he kept prolonging her life and she grew into powerful woman till Grim gathered the nerve to reap her. She married him instead and became ruler of the underworld alongside him. She had an affair with Nergal at one point which resulted in the human Minnie, which Grim was aware about, though he wasn't happy.

Dani and Manny

Two new additions to the Grim household born in between the end of "What About Mimi?" and "Afterbirth. They are the product of Mandy and Dark Danny sleeping together. As such they have ghost powers.

Allies and Extended Family


The temporal ghost from Danny Phantom. Acts an an observer and guide to Junior during his spiritual trip. Hinted that he knew was was to come (he a ghost of time after all). Grim doesn't seem to like him much.

Dark Danny

Danny's futuristic evil counterpart from The Ultimate Enemy. Clockwork released him in preparation for the coming events, with the threat that he'll erase him from existence (as D.D. exists outside of time now due to Danny's actions in the movie) if he gets out of line. Helps to fight against Minnie's monster form.


An otherworldly creature who has relations to Grim and Mandy. Comes to help out when Minnie's monster form runs rampant. Also has bad blood with Grim. The one present though seems to just be a spiritual apparition connected to the real one.

Nergal Jr.

Nergal's son, uncle to Junior and Minnie And Minnie's true father. Also comes to help out the group against Minnie's monster form.


Him and  Blossom's daughter. At first a voiceless and armless girl whom Junior meets while wandering a frozen tundra.  However this turned out to be a trap of Him to lure Junior to him. Once revealed, she transforms into a more devil like creature. She turns against Him and help Junior and Minnie escape once Jeff is threatened.

Jeff the Spider

Billy's "son" and Mimi's Nanny. Due to this he is at service of Him as he hopes Him can grant his wish of having his "father" love him. Despite this though, he still kind to a fault which plays a role in Junior and Minnie's escape from Him.


Lock, Shock and Barrel

The resident mischief makers of Halloween Town as well as Ooogie's minions. They befriend Junior while he mucking around by himself, who would later go on to explain how his parents got together to the three. However the whole thing is a trap to lure Junior to Oogie so he can take Junior hostage. The plan almost works, but they don't expect Minnie to come to Junior's rescue nor Ooogie actually murdering her. And especially don't expect Junior gaining Minnie's powers and using it to rip out their souls.

Ooogie Boogie

A evil resident of Halloween Town who is trying gain the title of the most scariest creature. However upon hearing that the Grims were in Halloween Town he changes his plans to try to usurp his position by kidnapping Junior and holding him hostage. Minnie comes to his rescue instead and easily handles Ooogie But thanks to Junior's callousness at being rescued by her, it gives Ooogie time to catch Minnie off guard and kill her. This however had the repercussion of Junior gaining her powers and using it to absolutely annihilate Ooogie.


The second baddie that Junior comes across (this time during his spiritual trip) and one of the PPG's toughest foes. He too is also after the power of the Grim family since he is at odds with them for the position for the underworld. As such he takes over Minnie's spirit and tries to use her to kill Junior. Things don't exactly go as planned however. When that plan goes south, he sends his daughter Mimi into the Grim family household to retrieve something for him which was revealed to the Hand of Horrors (as seen in the B&M movie The Big Boogie Adventure).
